- MPEG-2 Audio Simulation Software Distribution 07
- ================================================
- $Date: 1996/02/14 06:08:44 $
-
- This package contains source code for the MPEG-2 audio encoder and decoder
- under development by the MPEG/audio software simulation ad-hoc group. The
- package includes the multichannel and low sampling frequency extensions
- in MPEG-2 audio.
-
- The following table indicates the operations supported by the multichannel
- software in this distribution. Changes since the previous distribution are
- marked with an asterisk (*).
-
- There are no changes to the encoder in this revision. The decoder includes
- bug fixes to dynamic crosstalk, phantom center channel, and more audio
- channel configurations.
