Method and apparatus for correcting errors in digital audio signals

In correcting errors in a received digital data signal having a pair of parity series P and Q and including a CRC code, a parity check operation is performed for checking errors in either the parity series P or Q of the received digital data signals, error correcting operation is performed for correcting erroneous data of either the P series or the Q series data on the basis of an error pointer generated by the CRC code included in the recieved digital data signal, and a sequence of the parity check and error correcting operations is established for interposing at least one parity check operation among a series of error correcting operations.
