Philips' DCC incorporates the Precision Adaptive Subband Coding (PASC) algorithm that is capable of compressing two-channel stereo audio to 384 Kbit/s with near-CD quality [Lokhoff, 1992 ]. PASC can be considered as a simplified version of ISO/MPEG-1 Layer I; it does not require a side-chain FFT analysis for the estimation of the masking threshold.

MPEG audio • MPEG has proposed an audio scheme that is based on subband coding. • MPEG has proposed three coding schemes: Layer1, Layer2, Layer 3 • Coders are upward compatible: a layer N decoder is able to decode bitstream generated by the layer N-1 encoder • Layer1 and 2 coders use a bank of 32 filters.
