Looks like vorbis related software, question is whether this is in ecdoded
vorbis file or in winamp plyer.  Do try to decode to wav and play the wav.

Not yet and strict CBR - never.  Not evn MP3 does strict CBR, it has "bit
reservoir" tricks which is just limited ABR.  Vorbis should include a true
bitrate managment engine in RC3 which will give you choice from ABR (with
settable limits, currently limits are ignored) to true (quality-based)
VBR.  AFAIK ;).

Open winamp settings, input plugins, you should see it in the "Nullsoft
Vorbis decoder" name, if not select it and hit "about".  But it played
well for some time already anyway...

Maybe make a small sample of the wav and upload it somewhere.  Maybe
you've discovered a bug.  Does it happen to all your files systematically?
