Abstract

PURPOSE: To compensate the amplitude variation caused by the deformation of quantization and the delivery line error, by synthesizing audio through the use of normalized expected residual power obtained from the linear expected coefficient subjected to the effect of quantized error and the delivery line error.
CONSTITUTION: The analyser 106 calculates the linear expected coefficient from the audio waveform data and output it to the transmission line 102 after quantization 108. On the other hand, pitch frequency, no voice discriminating signal and audio wave information, and they are quantized 109 and outputted to the transmission line 103. The decoder 110 decodes the linear expected coefficient in which the delivery error is added and the normalized expected residual power is obtained with the calculator 113. Other decoder 116 decodes audio source information, causes the filter exciting signal with the exciting signal generator 115 from the said residual power, and it is fed to the audio synthesis filter 119. The filter 119 synthesizes audio from the linear expected coefficient and the excited signal.
