An audio data decoding device using the waveform encoding method includes: a loss detector, an audio data decoder, an audio data analyzer, a parameter correction unit, and an audio synthesis unit. The loss detector detects whether audio data has a loss. The audio data decoder decodes the audio data and generates a first decoded audio signal. The audio data analyzer extracts a first parameter from the first decoded audio signal. The parameter correction unit corrects the first parameter according to the result of the loss detection. The audio synthesis generates a first synthesis audio signal by using the corrected first parameter. Thus, it is possible to prevent deterioration of the sound quality in audio data error compensation.
