Re: [codec] Codec prototype

Hi,

It turns out that the code we sent yesterday had a pretty nasty bug that 
affected quality. I updated the snapshot and audio samples at 
http://people.xiph.org/~jm/ietfcodec/ . As you can see, there's now 
samples down to 24 kb/s.

Of course, this is still early work and we should be able to further 
improve quality.

Cheers,

	Jean-Marc
