MPEG-2 layer-3 multichannel decoder - pai_raviin - Sep 1 7:21:00 2005
Hi,
I am trying to implement the MPEG-2 layer-3 multichannel decoder,
backward compatible with MPEG-1 layer-3.
I am new to this work and I don't have any source code to implement
this decoder, but I got spec 13818-3.
Actually I am trying to build this multichannel decoder around the MPEG-
1 layer-3 and its low sampling frequency (lsf) stereo decoders like
MPEG2, MPEG2.5.
Main aim of this decoder is to support normal MP3 stereo decoding as
well as multichannel extension.
I would appreciate any help or suggestions.
Thanks,
Ravichandra

Hi simha j,
Thanks for your information.
I have gone through these websites but I didn't find the stuff related to multichannel decoder i.e, MPEG 2 layer-1/2/3 multichannel decoder.
If you have any idea about multichannel reference/source coder for MPEG2, please let me know.
Once again thank you very much.
Regards,
Ravichandra Reddy
