MPEG Audio Compression Advances

  • Schuyler Quackenbush


Recent MPEG audio coding work continues the quest for ever greater compression efficiency. It uses the tools of the MPEG-1 and MPEG-2 perceptual coders and adds a number of new mechanisms to achieve greater signal compression, giving it the following “compression toolbox”: Perceptually shaped quantization noise Parametric coding of high-band spectral components Parametric coding of the multi-channel of multi-object sound stage
