AAC+
[Audio Codecs]


Detailed Description

Example Usage:
   sc = Flix2_AddCodec(&codec, flix, FE2_CODEC_AACPLUS);
   // Use 128kbps
   if(sc == ON2_OK)
       sc = Flix2_CodecSetParam(codec, FE2_AACPLUS_BITRATE, 128);

Define Documentation

#define FE2_AACPLUS_BITRATE

Alias for FE2_CODECPARAM_BITRATE.

Codec parameter for stream bitrate.

Compressed stream bitrate in kbits/sec.

Note:
Default: 64

#define FE2_AACPLUS_PARAMETRIC_STEREO

Parameter for parametric stereo.

The Parametric Stereo technology was standardized by ISO 14496-3. It is a method to code stereo information and thus allows for further enhanced coding efficiency for lowest bit rate stereo coding. Combining Parametric Stereo with SBR and AAC yields the aacPlus v2 codec.
