Bug fixes and compliance to 13818-3.2 Revision 1.9 1997/01/19 23:00:48 rowlands Distribution 09. Improved code robustness for some combinations of parameters. 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 Revision 1.2 1995/06/16 11:12:43 rowlands Separated text documents Revision 1.1 1995/06/16 10:58:27 rowlands Initial revision ************************************************************************* MPEG-2 Audio Simulation Software Distribution 10 ================================================ $Date: 1997/01/28 12:00:48 $ 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. The multichannel encoder and decoder have been amended compared to dist09. The bug fixes mostly fix combinations of parameters which caused reliability problems. Furthermore both encoder and decoder are now compliant to 13818-3.2.

The following table indicates the operations supported by the low sampling frequency software in this distribution. The noise allocation in the layer 3 encoding procedure has been made more robust.
