[Flac-users] Extending mp3/ogg application to play flac
Hello,
Flac is great and I have encoded all my "good" CDs into it!
Now I want to extend an existing application able to decode mp3 and ogg
vorbis to replay flac as well. It is a plugin to a set top box

The existing code decodes into a mad_pcm structure using mad fixed point

to 32767 (0x00007FFF)
