For example, the scene as shown in Figure 1 can also be a conference scene, and the audio processing system 1 can be used to collect the conference content of the speaker A, and play the sound signal obtained after processing, so that more participants can Person B can hear the played audio signal and obtain the meeting content of speaker A. Alternatively, the scene shown in Figure 1 can be a classroom teaching scene, and the audio processing system 1 can be used to collect the voice teaching content of teacher A, and play the collected sound signal after processing, so that more students B can hear The played sound signal obtains the teaching content of the teacher A.
[0032] In some embodiments, the audio processing system 1 provided by the application includes: an audio processing device 10, a first microphone 20 and a speaker 30. The audio processing device 10 may be an electronic device such as a computer for processing sound signals, and the audio processing device 10 is respectively connected to the first microphone 20 , the second microphone 22 and the speaker 30 .
[0033] Wherein, the first microphone 20 is used to collect the sound signal spoken by the user A, and sends it to the audio processing device 10 for processing, and the audio processing device 10 performs subsequent processing on the sound signal.
Audio processing device 10 is used for receiving the sound signal from first microphone 20 (recorded as the first sound signal, distinguishes with the second sound signal collected by second microphone 22), and first sound signal After processing, it is sent to the speaker 30 for playback. The processing includes but is not limited to: echo cancellation (Acoustic Echo Cancellation, referred to as: AEC), automatic gain control (Automatic Gain Control, referred to as: AGC), automatic frequency control (Automatic Frequency Control, referred to as: AFC) and/or active noise Reduce (Adaptive Noise Reduction, referred to as: ANR) and so on.
[0035] The speaker 30 is used to play the sound signal after receiving the first sound signal sent by the audio processing device 10. In some embodiments, an amplifier (amplifier, AMP for short) may also be included between the audio processing device 10 and the speaker 30, which is used to amplify the first sound signal sent by the audio processing device 10 and then play it by the speaker 30. Amplified first sound signal.
In some embodiments, when audio processing system 1 is in actual use, because there is noise in the environment, audio processing device 10 can set "noise gate", that is, through the threshold value of the intensity of a sound signal, when playing For the first sound signal, part of the sound signals lower than the threshold value are filtered out, and only part of the sound signals higher than the threshold value are played, so as to prevent
The ambient noise received by the first microphone 20 is not played by the speaker 30.
For example, Fig. 2 is a kind of application schematic diagram of noise gate, wherein, the corresponding threshold value of the noise gate of note audio processing device 10 is D0, then at t0-t1 moment, first microphone 20 collects intensity and is d1 After receiving the first sound signal, the audio processing device 10 does not play the received first sound signal according to the intensity d1 of the first sound signal being less than D0. And at 11-12 moments, the first microphone 20 collects the first sound signal whose intensity is d2, and sends it to the audio processing device 10. After receiving the first sound signal, the audio processing device 10, according to the intensity of the first sound signal d2 is greater than D0, at this time, the audio processing device 10 plays the part of the first sound signal greater than D0 through the speaker 30.
In some other embodiments, when audio processing system 1 is actually used, the environment is complex and changeable, and the noise intensity existing in the environment may change at any time, for example, Fig. 3 is the application schematic diagram of another kind of noise gate , wherein, after time t2, assuming that user A instructs user B to discuss, the ambient noise will increase greatly after time t3, at this time, the intensity d3 of the first sound signal collected by the first microphone 20 will be greater than the noise gate The threshold value D0. Then at time t3-t4, even if user A does not speak, after receiving the first sound signal, the audio processing device 10 will play a part of the first sound signal whose intensity is greater than D0, and after the subsequent time t5, user A Without speech, even if the first sound signal only includes noise, the audio processing device 10 will play the part of the first sound signal whose strength is greater than D0, causing the audio processing system 1 to amplify and play the noise signal, and lose the effect of the noise gate. significance.
In some embodiments, the threshold value D0 of noise gate can be adjusted, such as being set in advance by the producer of audio processing device 1, or setting or adjusting by related personnel such as staff, user A or user B, However, this method still requires manual on-site testing and debugging, which makes the use of the audio processing system 1 more complicated and cumbersome, and consumes more manpower, debugging, maintenance and use costs.
In some embodiments, the application also provides a kind of audio processing system 1, makes audio processing device 10 can automatically adjust the threshold value of its noise gate "automatically" according to the noise of the current environment, thereby namely It has the function of the noise gate to filter the environmental noise, and can realize the adjustment and setting of the noise gate more intelligently and effectively, which saves the work of manual testing and setting the noise gate, and reduces the complexity and cost of audio processing 1. .
Fig. 4 is the structural representation of an embodiment of the audio processing system that the application provides, and audio processing device as shown in Fig. 4 is on the basis as shown in Fig. 1, also comprises: detecting device 40, is used for current The environmental noise is detected, and the detection result is sent to the audio processing device 10, so that the audio processing device 10 determines the noise intensity of the current environment according to the detection result. Subsequently, the audio processing device 10 can set the threshold value of its noise gate according to the noise intensity of the current environment.
In some embodiments, audio processing system 1 as shown in Figure 4 can be arranged in a casing, with the overall setting of a device; Or, the audio processing device 10 in audio processing system 1 is arranged in a casing , and can be connected with the external first microphone 20 , detection device 40 and speaker 30 through a wired or wireless connection.
In some embodiments, detection device 40 can be the second microphone, and the second microphone 22 is used for collecting the noise signal (denoted as the second sound signal) of the place environment of audio processing system 1, and the second sound signal that collects The sound signal is sent to the audio processing device 10 for processing.
[0044] In some embodiments, the first microphone may be a directional microphone and the second microphone may be an omnidirectional microphone.
In some embodiments, processors such as CPU can be integrated in the second microphone, so that after the second microphone collects the noise signal, calculate the noise intensity of the noise signal, and send the noise intensity information to the audio processing device 10, so that The audio processing device 10 directly receives the noise intensity determined by the second microphone, which reduces the amount of calculation performed by the audio processing device 10 .
In some embodiments, a plurality of second microphones can be included in the audio processing system 10, and each second microphone can be used to collect noise signals, and then the audio processing device 10 can send a plurality of second microphones according to the received The detection results jointly determine the noise intensity of the current environment, for example, the average or maximum value of the intensities of the noise signals collected by all the second microphones is calculated as the noise intensity. For example, the audio processing system 10 may include four second microphones, which are respectively arranged at four corners of the conference room, etc., for collecting environmental noises at the four corners.
Fig. 5 is the schematic flow chart of the setting method one embodiment of the noise gate that the application provides, has shown audio processing device 10 as shown in Fig. 4, according to the method flow process of the threshold value of its noise gate that its noise intensity is set ,include:
[0048] S101: The audio processing device 10 determines the noise intensity of its environment. Wherein, in order to adjust the threshold value of the noise gate, the audio processing device 10 first determines the noise intensity of the current environment. Since the audio processing system 1 includes the audio processing device 10, it also means that the audio processing device 10 determines the noise intensity of the environment where the entire audio processing system 1 is located. In one embodiment, the detection device 40 in the audio processing system 1 can collect the noise signal, and after calculating the noise intensity of the noise signal, the noise intensity is sent to the audio processing device 10 by the noise intensity information, then the audio frequency After receiving the noise intensity information from the detection device 40, the processing device 10 determines the noise intensity carried therein. At this time, the detection device 40 has the processing ability to replace the audio processing device 10 to calculate the noise intensity. For example, after the detection device 40 collects the noise signal, it calculates the average value or maximum value of the intensity of the noise signal as the noise intensity, and directly sends it to the audio system. The processing device 10 enables the audio processing device 10 to directly determine the noise intensity in S101.
In another embodiment, the detection device 40 in the audio processing system 1 is used to collect the noise signal, and the noise signal collected is directly sent to the audio processing device 10, then the audio processing device 10 receives the noise signal Afterwards, the noise intensity of the noise signal is specifically calculated by the audio processing device 10, for example, after the audio processing device 10 receives the noise signal collected by the detection device 40, the average or maximum value of the intensity of the noise signal is calculated as the noise intensity.
[0051] For example, FIG. 6 is a schematic diagram of calculating the noise intensity provided by the present application, assuming that the audio processing device 10 receives the noise signal sent from the detection device 40, between the first time period t3-t31. Then, before calculating the noise intensity, the audio processing device 10 performs filtering processing on the noise signal to filter out the sound signal with sudden change between t32-t33 in the noise signal. Wherein, the audio processing device 10 can set a preset fluctuation intensity range for the noise signal, such as d31-d32, and then determine that the intensity of the noise signal between t32-t33 exceeds the intensity range, and then determine the duration of t32-t33. If t33 is less than the preset time, it is determined that the part of the sudden sound signal is not a noise signal to be collected but a sudden interference signal, so this part of the signal is filtered out. Subsequently, the audio processing device 10 calculates the average value d3 of the intensity of the noise signal in the first time period after filtering as the noise intensity. Alternatively, the maximum value d31 of the intensity of the noise signal within the first time period may also be used as the noise intensity.
[0052] S102: The audio processing device 10 sets the threshold value of the noise gate according to the noise intensity determined in S101. Wherein, the audio processing device 10 may determine the first threshold value specifically according to the noise intensity, and then set the threshold value of its noise gate as the first threshold value. It can be understood that if the previous threshold value of the noise value is the second threshold value, the audio processing device 10 now adjusts the threshold value of its noise gate from the second threshold value to the first threshold value.
In some embodiments, the audio processing device 10 can directly use the noise intensity determined in S101 as the first threshold value, or, after adding the noise intensity and a preset value, obtain the first threshold value , so that the threshold value of the noise gate is slightly higher than the noise intensity, but the first threshold value should also be smaller than the intensity of the first sound signal, otherwise the first sound signal that should be played will be calculated as noise and not played.
Finally, after the threshold value of the noise gate is set to the first threshold value by the audio processing device 10 in S102, the audio processing device 10 subsequently receives the first sound signal from the first microphone, then the first The strength of the sound signal is related to the
A threshold value is compared, when the intensity of the first sound signal is greater than the first threshold value, the audio processing device 10 plays the part of the sound signal in the first sound signal whose intensity is greater than the first threshold value through the speaker 30; When the intensity of the sound signal is less than the first threshold, the audio processing device 10 does not play the first sound signal. In addition, when the intensity of the first sound signal is equal to the first threshold, the audio processing device 10 may play or not play the first sound signal, which may be set according to different scenarios or by different users.
In some embodiments, Fig. 7 is the application schematic diagram of a kind of noise gate that the present application provides, wherein, at t3 moment, the threshold value of the noise gate of audio processing device 10 is D0, subsequently, audio processing device 10 According to S101, it is determined that the noise intensity of the environment in the time period t3-t31 is d3, and according to S102, the threshold value of the noise gate is adjusted from D0 to D1 according to the noise intensity. Before time t31, since the noise intensity d3 of the environment where the audio processing device 10 is located is greater than the threshold value D0 of the noise gate, after the audio processing device 10 receives the first sound signal from the first microphone, even if it is a noise signal with an intensity of d3, Part of the noise signal greater than the threshold value will also be played through the speaker 30 . However, after the audio processing device 10 resets the threshold value of the noise gate to D1 at t31, it will not play the noise signal through the speaker 30 after receiving a noise signal with an intensity of d3, but will only receive a noise signal with an intensity of d3 between moments t4-t5. After the first sound signal with d1 greater than the threshold value D1, the part of the sound signal in the first sound signal whose strength is greater than the threshold value D1 is played through the speaker 30 .
Embodiment as shown in Figure 7 is compared with the embodiment as shown in Figure 3, because audio processing device 10 can improve the threshold value of noise gate correspondingly after t3 moment environmental noise intensity becomes larger, one On the one hand, the function of eliminating environmental noise can be maintained, and on the other hand, the unnecessary cost of manually adjusting the threshold value of the noise gate is reduced.
[0057] In some embodiments, the length between t3-t31 can be 5 minutes, 10 minutes or can be adjusted and set. In some embodiments, the audio processing device executes the noise gate setting method provided in the present application at intervals, for example, every 30 minutes, to set the noise gate, so as to maintain the real-time performance of the noise gate setting.
[0058] In some other embodiments, the audio processing device can increase the threshold value as shown in FIG. 7 when setting the noise gate, or, in other embodiments, can also reduce the threshold value, for example, as shown in FIG. 8 is a schematic diagram of another noise gate application provided by the present application, wherein, after time t5 as shown in FIG. The threshold value of the noise gate is lowered from D1 to D0, so that after time t8, the audio processing device 10 determines whether to play the first sound signal according to the noise gate of D0, which can improve the discrimination of the first sound signal.
In summary, the setting method of the noise gate provided by the present embodiment, and the audio processing system using the method, can actively determine the noise intensity of the environment by the audio processing device, and without manual setting, "automatically "Set the threshold value of the noise gate. Therefore, on the basis of enabling the audio processing system to have a noise gate for filtering out environmental noise, different environmental noises can be filtered out according to the intensity of different environmental noises, which can eliminate the noise received by the audio processing device when playing the first sound signal. The noise signal received, and the threshold value of the noise gate can be set flexibly, which can further reduce the cumbersome setting operations caused by different environmental noises when the audio processing system is used in different scenarios, and reduce the use of the audio processing system. The cost of manpower, commissioning, maintenance and use, greatly improves the user experience of the audio processing system.
As an example, when the audio processing system provided by the application is applied in a conference scene as shown in Figure 1, wherein user A uses the first microphone 21 to speak, the first microphone 21 collects the first sound signal of user A, And send to the audio processing device 10, the audio processing device 10 processes the first sound signal and sends it to the speaker 30 for playback. At the same time, the audio processing device 10 also filters the first sound signal through the noise gate D0, filters out the noise of other users in the first sound signal, and only plays the part of the first sound signal, including the speech content of user A whose intensity is greater than D0 sound signal. Subsequently, the meeting
During this period, when user A stops speaking to the first microphone 21 and discusses with all users B, the ambient noise signal in the conference room will increase greatly at this time, and the intensity may exceed the threshold value D0 of the noise gate. At this time, the audio The processing device 10 can set the threshold value of the noise gate to D1 according to the intensity of the noise, so as to filter out the environmental noise. When the user A speaks through the first microphone 21, even if the user B is still discussing, the noise from the user B can still be heard. B's ambient noise filtering does not affect the playing of user A's first sound signal, and the audio processing device 10 will not play the ambient noise through the speaker to affect user B's discussion.
In some embodiments, Fig. 9 is a schematic structural diagram of another embodiment of the audio processing system provided by the application, the audio processing system as shown in Fig. 9 is based on the embodiment shown in Fig. 4, and also includes : control device 50. The control device 50 can communicate with the audio processing device 10 through wired or wireless communication. The control device 50 may be a physical device such as a remote control or a button. When the control device 50 detects the click action corresponding to the closing command, it sends the noise gate closing command to the audio processing device 10, so that after the audio processing device 10 receives the noise gate closing command, The use of the noise gate is discontinued, and the first sound signal is played directly through the loudspeaker 30 after subsequent receipt of the first sound signal. In some embodiments, when the control device 50 detects the click action corresponding to the opening instruction again, it sends the noise gate opening instruction to the audio processing device 10, so that the audio processing device 10 reopens the noise gate.
