Comment (by mybobmy@…):
Replying to [comment:1 jyavenard]:
Time stretch might have been a red herring on this. It is more likely
related to creating the AC3 stream. I have a similar problem if I enable
upconverting to 5.1 with a stereo recording.
As for version, I'm dense when it comes to GIT. 'svn info' is so
simple... Best answer I've found is either :
git rev-parse HEAD: 8ed63e5222e81e711945815154eeec8a0dead83d
OR
git describe: v0.25pre-1866-g8ed63e5
There were no audio patches between when I built and when I posted the
bug.
