Hello,

I need to use AAC-LC codec encoder and decoder with C64X+ which should support standard 13818-3. I found MPEG4AAC-LC, but according to data sheet is supports 14496-3. Does it also support 13818-3 or should we use another codec for that ?

Best Regards,

Ran,

The standard of 14496-3 defines how it is compatible / overlaps with 13818-3. Not all features of 13818-3 are supported according to the standard.I suggest you consult with the 14496-3 and see which features of 13818-3 it does not support.

Regards,

Yair

Thank Yair,

Does it also mean that there is no codec which is AAC-LC compatible with 13818-3 ?

Ran,

Note that AAC standard was defined in 13818-7 also known as MPEG-2 NBC. This is when AAC was defined. 13818-3 is known as MPEG2-BC which is backwards compatible with 11172-3. See http://en.wikipedia.org/wiki/Advanced_Audio_Coding and http://en.wikipedia.org/wiki/MP3.
