From fa3eba16446cc8f2f5e2dfc20d86a49dbd37299e Mon Sep 17 00:00:00 2001 From: Jean-Michel Trivi Date: Thu, 29 Aug 2013 16:05:22 -0700 Subject: Encoder 7.1 support * AAC-Encoder - Add 7.1 rear surround and 7.1 front center support to supported encoder channel modes. Change max channels from 6 to 8 and add 7.1 configuration to bandwidth and channel mapping functions.

Changed max channels from 6 to 8. Modified file(s): libSBRenc\include\sbr_encoder.h libSBRenc\src\sbr.h libSBRenc\src\sbr_encoder.cpp libSBRenc\src\sbr_ram.cpp * Transport-Encoder - Add 7.1 channel configuration to audio specific config writer in transport encoder library. Modified file(s): libMpegTPEnc\src\tpenc_asc.cpp libMpegTPEnc\src\version * SYS-Library - Add 7.1 channel modes to CHANNEL_MODE description.
