I downloaded the code from http://lame.sourceforge.net for mp3. It has a function for decoding mp3. But the decoder does not have any filter of IMDCT. It seems to incomplete.

Can anyone let me know where can i fine Mp3 decoder code.

MAD should do fine:

or mpadec (in CVS):
http://sourceforge.net/projects/mpadec/


later

LAME has always worked well for me when I've needed to uncompress an mp3. I usually use EAC to run the decompression, but the end result has always been very good.
