I am working on digging out the MDCT values from madlib source codes. We need only the part of mad codes which only output mdct from mp3 frames.

But as a new beginner of mad and mp3 decoder, I am totally in a chaos now.

Even worse, the schedule is very tight...

So I am looking forward to the benevolance of anyone eagerly, who can tell me where I can find the MDCT values

and make a condensed package of lib which only outputs mdct during decoding.

After a call to mad_frame_decode(), frame->sbsample will contain the output from Layer III IMDCT synthesis; this is normally the input for polyphase synthesis via mad_synth_frame(), but you need not call this.
