<P>PROBLEM TO BE SOLVED: To provide a method of decoding digital audio data which is used to implement spectral formation of an audio signal during dequantization while depending on an error count confirmed by a checksum. <P>SOLUTION: In the method of decoding digital audio data used to implement error detection (2), dequantization (3) and filtering of digital audio data (1) as decoding steps, on the basis of the error detection for each frame or for each frequency domain, an error count of the digital audio data is determined, the error count is compared with a plurality of preset threshold values, an equalizer value is determined while depending on which threshold value the error count exceeds, and the equalizer value is used to implement spectral formation of the audio data during dequantization. In the case where the error count exceeds the threshold value, the audio data are attenuated by the equalizer value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
