System for output of audio signals

As well as the associated method and setting-up device

description

The present invention relates to a system for outputting audio signals.

Furthermore, the invention relates to a method for outputting audio signals via an output device as well as to a setting-up device for setting parameter values ​​for outputting audio signals.

When reproducing audio signals, whether music or speech, a strong dependence on the preferences of the respective user or listener with respect to the desired sound is shown, For example with regard to the frequency response, the dynamic behavior or also the specifications for signal enhancement methods. The setting of the parameters that can be set for playback is therefore individually, whereby existing hearing problems must also be taken into account.

At the same time, the individual listener nowadays has a plurality of output devices as terminals (eg loudspeaker systems, television, radio, computer, mobile telephone, fixed telephone, autoradio, etc.), software programs { Apps, (Eg listening to music, podcasts, or video conferencing) and a variety of application scenarios (eg listening to music or spoken texts, making calls or participating in video conferencing or chat systems) Adjustable parameters or which require different parameter values ​​in each case.

The optimal setting of the parameters must be set for each application or terminal or for each combination of the terminal and the application for an optimal listening experience. The necessary effort for the user is enormous. At the same time, the effort to provide corresponding user interfaces ("user interfaces") for the setting of the parameters on the side of the manufacturers of the application or the terminal means an additional cost and additional costs Or the absence of the necessary setting options usually leads to the user not taking any or only an incomplete individualization or pre- So that it is exposed to poor sound or, for example, For example, the language comprehension suffers or a higher degree of stress.

In order to reduce the effort or as a result of the lack of individualization or simply for reasons of cost, it is thus clear that, for many devices or applications, only very simplified possibilities for sound adaptation (eg only volume or only high / low) Can be implemented.

Overall, the potential of modern audio signal processing, For example also with regard to the adaptation to the listening environment or an existing one at the listener

Hearing loss, not always exhausted.

The object of the present invention is therefore to make the individualization of the output of audio signals simpler and thus to render the listener more comfortable.

The invention solves the invention with a system for outputting audio signals.

The system has a first output device for outputting audio signals, at least one data memory for storing parameter values, and at least one management device. The first output device is configured to output audio signals with predefinable parameter values ​​of a first set of adjustable parameters. Furthermore, the management device is configured to access the data memory. Furthermore, the management device is configured to search in the data memory for stored parameter values ​​for a set of parameters which is equal to the first set of parameters or similar to the first set of parameters. The search refers to the search of the data store, In some embodiments, according to particular criteria or by the restriction to parts of the stored data. Finally, the management device is configured such that, in the event that the management device has found stored parameter values ​​for the set of parameters in the data memory, the management device transmits the stored parameter values ​​for the set of parameters to the first output device and / or from the stored output parameters Parameter values ​​transferred to the first output device The adjustable parameters are, for example, the volume, to adjust the setting of treble or bass, or the special setting of one- Frequency bands, characteristics for modifying the dynamics capture, degree of application of signal conditioning algorithms, etc. The adjustable parameters can also be used, for example, For example, be values ​​with which the filter function of an equalizer is determined and adjusted. The determination relates in particular to the calculation of parameter values, Eg by means of a mean value image, by an extra or interpolation, by spline formation or by a change in a sampling rate, etc. This also includes, for example, complex parameters and preferences, such as the hearing loss of a listener / user, which is then used to determine settings, such as The parameters of a frequency-dependent dynamic compression. In the system according to the invention, a (first, Alternative designation is current) output device - as a terminal - to the actual output of the audio signals. For output, the output device has several adjustable parameters whose parameter values ​​can be specified and which together form a (first) set of parameters.

Furthermore, a data memory is provided, in which parameter values ​​can be stored. Preferably, the combination of sets of parameters and associated parameter values ​​is stored.

In addition, a management device is also provided which accesses the data memory and searches there for an existing, ie, stored, set of parameters which is either equal to the set of parameters of the (first or current) output device or which is similar to this set. If such a matching set of parameters has been found, the management device transmits the parameter values ​​associated with the matching set to the (first) output device. Alternatively or additionally, the management device transmits to the first / current output device parameter values ​​which have been determined or derived from the stored parameter values. From the parameter values ​​assigned to and stored in the set of parameters found, other parameter values ​​are thus generated and transmitted to the output device. The transmitted parameter values ​​- previously stored or determined - are then used by the (first) output device for the output of the audio signals. The invention is illustrated by a practical example, while at the same time discussing exemplary embodiments: The user or listener adjusts the parameters of an output device in such a way that an optimum sound picture is obtained. The corresponding parameter values ​​are stored in the data memory. If, at a later time, the listener wishes to have audio signals output via the output device, the management device searches for the relevant set of parameters in the data memory and transmits the associated parameter values ​​to the output device, which then uses these parameter values ​​to transmit the audio signals For the listener optimally - namely with the parameter values ​​set by him. If the output device for which the listener has set the optimum setting and the output device via which he currently wants to hear the audio signals are different, But similar devices, then only a similar set of parameters is found in the data memory. In this case, the management device transmits parameter values ​​to the current output device, which the management device has determined from the stored parameter values. During the determination, the respective parameter values ​​are transmitted, for example, for identical parameters. For different parameters, For example, the respective parameter values ​​are determined from other parameters or their parameter values. This is done, for example, Eg by extrapolation, by averaging or by an estimation based on other parameter values. In this case, the management device transmits parameter values ​​to the current output device, which the management device has determined from the stored parameter values. During the determination, the respective parameter values ​​are transmitted, for example, for identical parameters. For different parameters, For example, the respective parameter values ​​are determined from other parameters or their parameter values. This is done, for example, Eg by extrapolation, by averaging or by an estimation based on other parameter values. In this case, the management device transmits parameter values ​​to the current output device, which the management device has determined from the stored parameter values. For the determination, the respective parameter values ​​are transmitted, for example, for identical parameters. For different parameters, For example, the respective parameter values ​​are determined from other parameters or their parameter values. This is done, for example, Eg by extrapolation, by averaging or by an estimation based on other parameter values. For different parameters, For example, the respective parameter values ​​are determined from other parameters or their parameter values. This is done, for example, Eg by extrapolation, by averaging or by an estimation based on other parameter values. For different parameters, For example, the respective parameter values ​​are determined from other parameters or their parameter values. This is done, for example, Eg by extrapolation, by averaging or by an estimation based on other parameter values.

In one embodiment, the system has an interface for detecting the parameter settings set by an output device. In addition, information about the environmental situation, ie, the contexts in which the output of the audio signals take place, and / or via the respective user, can be recorded via the interface. The user can also exist in a group of individuals. The information may have some abstraction (such as the audiogram of a listener) or even concrete values. In one embodiment, the relevant information is recorded offline and is transmitted to the management device or the data memory only at a later time.

In a further embodiment, an interface is provided, which allows the transmission of the parameter values ​​to the current or first output device. In a The information is transmitted offline and therefore before the actual output of the audio signals.

In other words; The predetermined - historical - parameter values ​​for the output with an output device (in the application, for example, referred to as a second output device) are used for the - preferably automatic - setting of the parameter values ​​of the audio-signal output via a currently affected output device As the first output device). Overall, the system has the great advantage for the user or listener that he does not have to set the parameters individually for all output devices, but instead the system assumes this from existing records for him. Not only the output devices or terminals, in which the user has already made settings, are taken into account, For which no user-specific adjustment has been made. Therefore either the direct output of the stored parameter values ​​or the output of the determined or derived parameter values.

A further advantage is that the setting of the parameters and the application of the parameter values ​​are separated from each other, so that the set parameter values ​​are available at arbitrary times and under any applications, and in particular also an automatic determination of parameter values, For example in the form of calculations. An advantage for the manufacturers of output devices, ie of terminals, can be to dispense with special interfaces for the setting of the devices, since the preferences or settings are managed centrally.

The following embodiment relates to the storage of the parameter values ​​in the data store, which can then be accessed by the management device.

In this case, the system additionally has a second output device for outputting audio signals, which is provided, in particular, only temporarily. The second output device is configured to output audio signals with predefinable parameter values ​​of a second set of adjustable parameters. Furthermore, the management device is configured in such a way that, after predefining the parameters, Second values ​​of the second set of parameters at least the set parameter values ​​in the data memory. After predefining the parameter values ​​of the second set of parameters, the predefinable parameter values ​​of the second set of adjustable parameters are set to set parameters. The second (an alternative designation would be: historical) output device, in particular, is part of the system before the first (current) output device and serves the user or the listener for setting the parameters which influence the output of the audio signals. If the settings have been made, ie if the user has specified the parameter values ​​for the second output device, the management device stores the parameter values ​​for further use with the first output device. The predefining of the parameter values ​​is, in particular, that a user of the second output device makes settings on the output device, so that the optimum sound image results for him. In one embodiment, the first output device and the second output device are different output devices, which in one embodiment are at least the same type of output devices and which are of different types in an alternative embodiment. The type of the output device relates in one embodiment to the devices per se, ie whether they are computers, stereo systems or, Such as smartphones. The type is, in another embodiment, the same basic type, but different versions or classes. In a further embodiment, the first output device and the second output device are the same, For example, the identical output device is connected to the system twice. In the last embodiment, the system makes it virtually possible to remember the parameter values.

Depending on the embodiment, the stored parameter values ​​of the second output device therefore refer to identical, similar or different sets of parameters as the set of parameters of the first output device.

Alternatively or additionally, the parameter values ​​are stored directly in the data memory, and without the detour via the setting on an output device. This is done, for example, For example, by means of an interface which allows a direct input of parameter values ​​of the parameters which can be set in the case of an output device. In one embodiment, it is provided that the management device is configured in such a way that, Eg directly from the current or first output device, soft parameters are to be set in the first output device. The management device therefore receives the information about the first set of parameter values ​​to be filled with parameter values.

For a further processing of the parameter values ​​or for the finding of the data records, it provides for a configuration that the management device is configured such that the set parameter values ​​correspond to a type of the second output device and / or a user and / or an environmental situation and / Signals and / or a type of the audio signals to be output in the data memory. The type of the output device is also stored in a variant according to the parameter values, which are set in an embodiment in the second output device. The type refers, for example, to the associated parameters or to the options for setting the parameters or also to the application type.

Alternatively or additionally, the parameter values ​​are stored for a particular user or environment. The ambient situation or listening situation is the environment in which the audio signals are reproduced. Reference may be made here to the statements in DE 10 201 1 076 484 A1. The ambient situation has an effect on the volume.

In addition, or alternatively, the parameter values ​​are stored as a function of a type or a type of the audio signals. Thus, the audio signals are stored, for example, as voice signals or music signals, as classic, jazz or pop signals, as film signals, etc., or possibly by an input from the user or by an evaluation of the audio Signals. The type of the audio signals may also be mixed or, if appropriate, may also be predetermined by the type of application or the terminals. Thus, the audio signals transmitted by telephone will generally be voice signals. This further classification allows a further precise adjustment of the listening preferences, which can also take into account the respective signals and their characteristics. Speaking evaluation or further processing of the parameter values, in particular in the event that parameter values ​​are not stored in the data memory for all parameters which are acutely required for the respective application or the respective output device.

In one embodiment, the management device is configured to consider a user assigned to the first output device in the search in the data memory according to the stored parameter values ​​for the set of parameters. The user is the listener who, Eg, the user who is currently using the output device for the output of the audio signals. The consideration is made in that the management device prefers such stored parameter values ​​for sets of parameters which are assigned to the user or users with preferences similar to the user. The preferences refer to the fact that the user and the other users belong to the same group of listeners (for example, classic or rock music friends). The preferences refer, alternatively, That similarities in the settings, For example, the preference for the bass range or other frequency bands. The preferences can be similar to equality. The similarity may be that the deviations lie within a predeterminable deviation band.

Thus, other types of output devices are also taken into account, in that the general preferences can only be crystallized out by comparing the parameter values ​​for different output devices with the users or the user. The reference to the individual listeners presupposes that the data stored in the data memory are also assigned to the individual users or users. Thus, in one embodiment, it is provided that the That the data stored in the data memory are also assigned to the individual users or users. Thus, in one embodiment, it is provided that the That the data stored in the data memory are also assigned to the individual users or users. Thus, in one embodiment, it is provided that the Users log on to the management device with their current output device.

In an embodiment, it is provided that the management device is configured in such a way that, in the search in the data memory, a current environmental situation on the first output device is taken into account according to the stored parameter values ​​for the set of parameters by the storage device storing parameter values ​​for sets of parameters, Which are assigned to environmental situations similar to the current environmental situation. The preference is that the assigned data or parameter values ​​have a higher priority in the search. In this case, the parameter values ​​which relate to the same or similar environmental situations are preferred in particular. This is, for example, a car ride to play in a closed or open space,

In an alternative or supplementary embodiment it is provided that the management device is configured in such a way that the audio signals to be output are taken into account in the search in the data memory for the set of parameters by storing the parameter stored by the management device^¬ Is preferred for sets of parameters which are assigned to the audio signals which are similar to the audio signals to be output. In this embodiment, the parameter values ​​which relate to similar signal types or signal types are therefore preferred. These are, for example, voice signals in contrast to music signals or radio play signals in contrast to telephone calls, etc. In this embodiment, it is therefore taken into account that the audio signals themselves can also have an influence on the respective listening preference. For example, in voice signals, other frequency ranges are amplified than in the case of music. Furthermore, one embodiment provides that the management device is configured such that the management device, in the case, A parameter value is missing from the data memory for the first set of parameters, the parameter value stored in the data memory at least determines the missing parameter value. This embodiment relates to the case in which the first set of parameters of the first output device comprises at least one parameter to which the data memory has no parameter value, which is therefore missing. In this case, The missing parameter value is determined by determining the missing parameter value from the existing parameter values. This occurs, for example, in which an average value is generated from the existing parameter values ​​or an extra or interpolation is performed.

Depending on the situation, several parameter values ​​may be missing, or there may even be the case that there is no matching set in the data store for a complete set of parameters. In the case of the complete absence of a set of parameters, it is provided in an embodiment that the management device issues a message. For example, For example, the situation in which there is no comparable set of parameters. Alternatively, the parameter values ​​from stored parameter values ​​are also determined with a completely missing set of parameters. In a subsequent embodiment, the management device is configured such that, When determining the missing parameter value, the parameter values ​​assigned to a user and stored in the data memory. In one embodiment, only the parameter words assigned to a user are used for determining the missing parameter value or the missing parameter values ​​or even all parameter values ​​for a complete set of parameters. The audio signals are output to the user via the first / current output device. In this embodiment, the particular preferences of a user in the form of the stored parameter values ​​are thus preferably used or, in particular, only for the determination of the missing parameter values. For this embodiment, it is therefore advantageous, If the corresponding user is also stored to the parameter values. Furthermore, a possibility is advantageously realized by means of which the user can make himself known to the system or to the management device.

For the following embodiment, there is in particular the case that no set of parameters is present in the data memory which is equal to the first set of parameters of the first output device. The embodiment provides that the management device is configured such that, in the event that the management device has found in the data store a set of parameters which is similar to the first set of parameters, the associated and stored parameter values ​​are adapted to the first set of parameters And to transmit the adapted parameter values ​​to the first output device. The management device therefore adapts the parameter values ​​of the set of parameters similar to the set of parameters of the first output device so as to match the first set (currently required for the output of the audio signals) of parameters to be output from the first output device The output of the audio signals to be used.

In the following embodiment, the parameter values, which are assigned to a user, are bundled into an abstract overall image. Thus, in one embodiment, the management device is configured such that a user profile for the user can be generated out of the parameter values ​​assigned to a user and stored in the data memory. A user profile describes the preferences of the affected user on an abstract level detached from the output devices or environmental conditions, Eg easily missing parameter values. The user profile is determined, for example, For example with methods for dynamic learning. The parameters can be combined at the concrete level and at the abstract level. For example, for a situation, the parameter values ​​for a set of parameters can fall out of the general or abstract context of a user profile, and, if necessary, be absolutely necessary for the application in such a situation. For example, a user might prefer that the voice signal from a mobile phone be strongly amplified during an incoming train (or generally "loud noises"), while another user may not hear very loud signals, and therefore a non-understanding of the call In the future.

In one embodiment, the system comprises, For example, only temporarily - a fourth output device for outputting audio signals, the fourth output device being configured to output audio signals with predefinable parameter values ​​of a fourth set of adjustable parameters. Furthermore, the management device is configured such that it is emanating from the user profile generated! Parameter values ​​for the fourth set of parameters of the fourth output device are determined and sent to the Fourth output device. Starting from this embodiment, in a further variant, the search for a suitable set of parameters for the fourth output device is omitted, and the parameter values ​​for the fourth set of parameters for the fourth output device are determined directly using the at least one user profile To the fourth output device. The fourth output device is thus also a current output device, such as the first output device, but the parameter values ​​are determined specifically via the user profiles. Therefore, in an alternative variant, the search for the sets of parameters can be dispensed with by working directly with the abstract user profiles, In order to determine the currently required parameter values ​​from the user profiles. In a further embodiment, the management device is configured such that a user profile for another user can be determined from the user profile created for the user. The Userprofi! For the other user, the parameter values ​​for a set of parameters are limited in one embodiment. The application of the transmission of listening preferences consists, in one embodiment, in that the parameter values ​​are compared with one another by different users, and that in the case of a resulting similar user profile, For example, the parameter values ​​of a user with an output device and / or in an environmental condition for another user. This da on outgoing,

In one embodiment, it is provided that the data memory is designed in a cloud-based manner. The data store is thus at least partially implemented via a cloud. This arrangement emphasizes even more that the (central) administration of the data and the application of the data are spatially separated from each other.

The data store, Eg in the form of a Cioud, makes it possible, in one embodiment of a plurality of users, to change and preferably improve the stored parameter values ​​and / or generated user profiles and / or algorithms for determining parameter values. Furthermore, the invention solves the problem by a method for outputting audio signals via an output device, the method comprising at least the following steps: searching for a set of parameter values ​​for a set of parameters corresponding to a set of adjustable parameters of the output device The parameter values ​​and / or parameter values ​​determined therefrom are transmitted to the output device, and in that the audio signals are output via the output device using the transmitted parameter values become.

The above statements on the system and / or its configurations and explanations also apply correspondingly to the method or the embodiments of the method can be implemented by means of corresponding device variants so that the explanations on the method apply correspondingly to the system.

Furthermore, the invention relates to a computer program with a program code for carrying out the method according to one of the above claims based on the statements on the system. Furthermore, the invention solves the problem by a setting device for the setting of predeterminable parameter values ​​of a first set of adjustable parameters of an output device for outputting audio signals with the prescribable parameter values. The setting device has at least one data memory for storing parameter values ​​and at least one management device. The management device is thus configured to access the data memory. Furthermore, the management device is configured such that, In the data memory for a stored parameter value for a set of parameters which is equal to the first set of parameters or similar to the first set of parameters. Finally, the management device is configured such that, in the event that the management device has found stored parameter values ​​for the set of parameters in the data memory, the management device transfers the stored parameter values ​​for the set of parameters and / or parameter values ​​determined from the same to the First output device. The determination of the parameter values ​​consists in one embodiment in the direct transmission to an output device and consists in an alternative or supplementary embodiment in a calculation or Which is equal to the first set of parameters or similar to the first set of parameters. Finally, the management device is configured such that, in the event that the management device has found stored parameter values ​​for the set of parameters in the data memory, the management device transfers the stored parameter values ​​for the set of parameters and / or parameter values ​​determined from the same to the First output device. The determination of the parameter values ​​consists in one embodiment in the direct transmission to an output device and consists in an alternative or supplementary embodiment in a calculation or Which is equal to the first set of parameters or similar to the first set of parameters. Finally, the management device is configured such that, in the event that the management device has found stored parameter values ​​for the set of parameters in the data memory, the management device transfers the stored parameter values ​​for the set of parameters and / or parameter values ​​determined from the same to the First output device. The determination of the parameter values ​​consists in one embodiment in the direct transmission to an output device and consists in an alternative or supplementary embodiment in a calculation or In the event that the management device has found stored parameter values ​​for the set of parameters in the data memory, transmits the stored parameter values ​​for the set of parameters and / or parameter values ​​determined from the same to the first output device. The determination of the parameter values ​​consists in one embodiment in the direct transmission to an output device and consists in an alternative or supplementary embodiment in a calculation or In the event that the management device has found stored parameter values ​​for the set of parameters in the data memory, transmits the stored parameter values ​​for the set of parameters and / or parameter values ​​determined from the same to the first output device. The determination of the parameter values ​​consists in one embodiment in the direct transmission to an output device and consists in an alternative or supplementary embodiment in a calculation or (Eg by accessing a data table) of the currently required parameter values.

The above explanations regarding the system and / or its configurations and explanations also apply correspondingly also for the Einsteilvorrichtung as part of such a system.

The adjusting device and at least one output device complement one another in particular with respect to the above system so that the corresponding embodiments and embodiments also apply with respect to the system for the adjusting device. In detail, there are a plurality of possibilities for designing and further developing the system according to the invention, as well as the method according to the invention and the adjusting device according to the invention. Reference is made, by way of example, to the patent claims, on the other hand to the following description of exemplary embodiments in conjunction with the drawing. Show it:

FIG. 1 schematically shows a system for outputting audio signals in a first embodiment

configuration

FIG. 2 schematically shows a system in a second embodiment and FIG

FIG. 3 is a flowchart of an example of the method.

FIG. 1 shows schematically an exemplary system for outputting audio signals. The first output device 1 is here represented by a loudspeaker, which is intended to have, for example, four switches for the presetting of parameter values ​​of four parameters. The four parameters thus form the first set of adjustable parameters.

Different parameter values ​​for different sets of parameters are stored in a data store 2, which is here a part of a management device 3. The central data memory 2 permits the operation or adjustment of different distributed output devices. In this case, the output devices can differ from each other in terms of their specific design, ie with regard to their hardware, or with regard to the application operated on the same device, by means of which the same device becomes, as it were, a different device. For example, a computer can be used for playing music or performing Video communication, thus resulting in different output devices.

In the example shown, the management device 3 is configured to search in the data store 2 for a stored set of parameters matching the first set of parameters of the first output device 1. In this case, "fit" means that the found sentence (ie, stored and, as it were, historical) sentence is equal to the first sentence (that is to say, to be filled with parameter values ​​and current), or that the found sentence is similar to the first sentence, (Eg, pure speech or classical music) and / or that a plurality of parameters are associated with the same, and / or that the sentences are related to similar terminals is equal to. Depending on the application, the similarity must therefore be defined. If the management device 3 finds a suitable set of parameters, it transmits the associated parameter values ​​to the first output device 1, which is thus indicated by radio waves, and therefore has suitable parameter values ​​without a direct intervention by the user 6. In the embodiment shown, the sets of parameters and their values ​​are derived from a second output device 4 and a third output device 5. The second output device 4 should be the same as the first output device 1 and the third output device 5 is to be different from the first output device 1. The differences refer to the terminal (illustrated by two in contrast to three membranes) itself, But also to the number of adjustable parameters (four parameters as opposed to three parameters). The connection between the management device 3 and the second 4 and third output device 5 takes place, for example, via cables. If, therefore, a user 6 has made the setting of the parameters on the second output device 4 or on the third output device 5 (both output devices 4, 5 are relative to the first, current output device 1, historical output devices), these parameter values ​​also apply to the first output device 1 automatically. The parameter values ​​can either be transferred directly (here from the second output device 4) or can be obtained via The connection between the management device 3 and the second 4 and third output device 5 takes place, for example, via cables. If, therefore, a user 6 has made the setting of the parameters on the second output device 4 or on the third output device 5 (both output devices 4, 5 are relative to the first, current output device 1, historical output devices), these parameter values ​​also apply to the first output device 1 automatically. The parameter values ​​can either be transferred directly (here from the second output device 4) or can be obtained via The connection between the management device 3 and the second 4 and third output device 5 takes place, for example, via cables. If, therefore, a user 6 has made the setting of the parameters on the second output device 4 or on the third output device 5 (both output devices 4, 5 are relative to the first, current output device 1, historical output devices), these parameter values ​​also apply to the first output device 1 automatically. The parameter values ​​can either be transferred directly (here from the second output device 4) or can be obtained via If, therefore, a user 6 has made the setting of the parameters on the second output device 4 or on the third output device 5 (both output devices 4, 5 are relative to the first, current output device 1, historical output devices), these parameter values ​​also apply to the first output device 1 automatically. The parameter values ​​can either be transferred directly (here from the second output device 4) or can be obtained via If, therefore, a user 6 has made the setting of the parameters on the second output device 4 or on the third output device 5 (both output devices 4, 5 are relative to the first, current output device 1, historical output devices), these parameter values ​​also apply to the first output device 1 automatically. The parameter values ​​can either be transferred directly (here from the second output device 4) or can be obtained via An adaptation from the stored historical parameter values ​​(here from the third output device 5).

If the user subsequently changes the parameter values ​​on the first output device 1, these are then again taken into the data memory 2 and stored. In the example, the different parameter values ​​are due to the fact that the first output device 1 is located in a free ambient situation 7, while the second output device 4 and the third output device 5 are arranged in a closed environment situation 8, indicated by the box.

FIG. 2 shows a system in which the user 6 on the second output device 4 specifies the parameter values ​​for the second set of parameters, which comprises four parameters. These parameter values ​​are transmitted by radio to the management device 3 and are stored in the data store 2, which is implemented here in a cloud. In addition, the management device 3 generates from the parameter values ​​a user profile 9 for the user 6, which is likewise stored in the data memory 2.

The management device 3 uses the stored user profile 9 to determine therefrom the parameter values ​​for a fourth output device 10 and another user 11 (or general user). One parameter refers to one

Loudspeaker (second output device 4) and the other parameters to a headphone (fourth output device 10). For this purpose, for example, the parameter values ​​relating to the volume are correspondingly scaled down.

Furthermore, the parameter values ​​for a different user 1 1 are also converted. For this conversion, the user profiles 9 of the one user 6 stored in the data memory 2 and the user profile 12 of the other user 11 are compared with one another in order to enable a comparison of the parameter values.

FIG. 3 shows a schematic sequence of the method according to the invention.

In step 100, a user at an output device (referred to above as a second output device) adjusts the parameters so that the optimum sound is obtained. The parameter values ​​are specific to the user, but also to the output. For the type to which the output device belongs, as well as for the given ambient or hearing situation.

The parameter values ​​are stored in step 101.

Now the user would like to output audio signals via another output device, for which he starts the output in step 102.

For this purpose, it is queried in step 103 which parameters can be set in the other output device. It is therefore determined which set of parameters is required.

Then, in step 104, the amount of the stored data is searched for a set of parameters that are similar to, or similar to, the required set of parameters.

Depending on what is found for a set of parameters, different steps follow after step 105. If the same set of parameters has been found, the associated parameter values ​​are passed to the output device in step 106, and in step 107 the output device outputs the Audio signals with the appropriate parameter values.

If the sets of parameters are not the same, then the required parameter values ​​are determined from the stored parameter values ​​in step. Thus, for example, the parameter values ​​are adopted for the same parameters, and approximation methods for calculation or determination are used for mutually differing parameters. If, for example, only the settings for two frequency ranges are available, if the settings of three frequency ranges are required, the settings, ie the parameter values, are determined by extra or interpolation for the missing frequency range.

The determined parameter values ​​are transmitted to the output device in step 109 in order to find use there for the output of the audio signals in step 1. Overall, according to the embodiment, the invention allows parameter values ​​to be transmitted between different output devices, but also between different users / listeners or listener groups. The historical parameters are obtained from the settings on output devices or can also be stored directly as pure data (ie, for example, an Audiogram). The currently required parameter values ​​are either taken unchanged from the stored parameter values ​​or are determined from the stored data or by the use of generated user profiles. From the existing historical data material there is, in particular, an adaptation to the possibilities of the current output device.

The invention therefore permits the transmission or application of the respective personal sound preference to the respectively current audio situation. Furthermore, the parameter values ​​can also be related to the respective type of the audio signals or the audio signals themselves and differ from one another in this respect. If the audio signals are, for example, For example, jazz, the parameter values ​​may be different from those for the reproduction of a piano piece by JSBach. In another example, a user 20 prefers to play high-pitched speech because it has high-frequency hearing and thus can better understand. In the case of music as a different audio signal type, however, it prefers the emphasis of the bass, because this meets its taste.

Furthermore, the management device is also capable of learning to improve the algorithms it employs and adapt to the requirements. Thus, in one embodiment, the management device automatically adjusts the user profiles to any further specification of parameter values.
