$Log: readme.1st $
Revision 1.7 1996/02/14 06:08:44 rowlands
Distribution 07. Added much multichannel encoder and decoder
functionality. Added complete layer 3 to low sampling rate.
Revision 1.5 1995/07/14 08:14:16 rowlands
Added more audio channel configurations, fixed dynamic crosstalk
bugs, and added two-channel low sampling frequency support.
Revision 1.4 1995/06/22 01:25:45 rowlands
Distribution 04, with decoder dynamic crosstalk
Revision 1.3 1995/06/19 03:30:12 rowlands
Distribution 03, with decoder mods and bug fixes

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.
