I've been kind of busy lately, but I wanted to see what's up with ao after the build change. I was able to check out the vorbis module, but when I tried to check out the ao module I saw this: [stan@volsung vorbis]$ cvs -d:pserver:anoncvs@cvs.xiph.org:/usr/local/cvsroot co -r branch_postbeta2 ao cvs server: Updating ao cvs server: Updating ao/doc cvs server: Updating ao/include cvs

Is there any dump utility that exists for vorbis streams? What I am intersted in is something that will do a break down like: How many bits are used for encoding _each_ codebooks, how many bits are used for the residue, how much is used for the lpc coefficints. A selective dump of the codebooks themselves would be nice too of course. I'm wondering if anyone has such a little dump utility.
