Hi all!

Does anyone have experience with encoding mono wavs to vorbis? I'm considering encoding live-recorded speech along with some classical instrumental and choral music to both a "high quality" (44100, some 60-80 kbps) and a "modem" version (22050, or 44100 if acceptable, 20-30 kbps). From what I've read, some of the third-party encoder tunings like aoTuV or GT3 either didn't/don't have mono tunings at all, or just produce(d) garbage on mono input. Maybe this is because the third-party tunings try to solve problems occuring specifically with stereo files? Does anyone have any recent information on which encoder tuning(s) work best for mono input?

I've done extensive mono encodings, and Ive used the Garf tunings for some mono encodes and they turned out ok (as in no garbage).

Personally, I'm using a stock 1.0.1 Post-CVS compile on both of my encoding environments, and I'm happy.

Now, I havnt done any hardcore tests, as my application is more dependant on overall size then it is on minor quality differences, and I havn't had time, so it woulndt be a bad idea to take a 10sec sample and feed it through a couple of encoders and see the differences, or even go as far as to do a blind test, but I havn't needed to yet.

One note: in mono, I generally get 60-80kbps arround q4 or so. (I use q5 and hit about 85kbps or so)

Good luck.
