Do in part because of advice offered here, we were able to incorporate the an ogg-vorbis decoder into our software. The encode stays with another piece, and this has kept software size down considerably. I was wondering why the encoding was so large? And for my own benefit, are there some books I could study to learn the mathematical background (or anything else I would need to completely understand the vorbis compression architecture) of vorbis?

Thanks, ChrisMost of the encoder size comes from the large static codebooks included. It'd be possible to make a significantly smaller encoder if you wanted to limit it to, for example, only one bitrate/mode (just by not including the other modes and associated codebooks).
