* Encoder 7.1 supportJean-Michel Trivi2013-09-031-21/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* Encoder ELD auto configuratorJean-Michel Trivi2013-09-031-2/+30
| | | | | | | | | | | | | | | | * AAC-Encoder - Introduce ELD auto configurator to get predefined configuration at given bitrate and sampling rate. The configurator selects SBR on/off and if SBR enabled distinguishes between dualrate and downsampled SBR. In default configuration the ELD auto configurator is enabled.

* Encoder explicit signalingJean-Michel Trivi2013-09-031-8/+44
| | | | | | | | | | | | | | | | | | | | | * AAC-Encoder - Revise explicit signaling method which is required for downsampled SBR. The parameter is optional and default configuration is implicit signaling for dualrate SBR as before. In case of downsampled SBR and HE-AAC explicit signaling is configured as default.

* Encoder downsampled SBRJean-Michel Trivi2013-08-291-13/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * AAC-Encoder - Introduce optional AACENC_SBR_RATIO encoder API parameter to configure dualrate or downsampled SBR explicitely. ELD makes use of downsampled SBR in default configuration. Modified file(s): documentation\aacEncoder.pdf libAACenc\include\aacenc_lib.h libAACenc\src\aacenc.h libAACenc\src\aacenc_lib.cpp * SBR-Encoder - Implement downsampled SBR feature. - Revise sbr tuning parameter selection.
