  • iTunes AAC 6.0.1.3
  • LAME 3.97 Beta 2
  • Ogg Vorbis AoTuV 4.51 Beta
  • WMA Professional 9.1

Oh, btw - ABC/HR seems to start playing the samples at about .3 secs every so often. Is this a known issue? It's really annoying, that's for sure... blink.gif

It should start playing at 2 seconds. That is not a bug, it's a feature. biggrin.gif

[...]let encoders adapt themselves to the content by not testing the first few seconds of the sample.
If you encode a few seconds at the beginning that are not tested by the listener, you solve the problems of psymodel adaptation and bitrate management adaptation.

What I'm talking about happens even if you select a small part in the middle of the sample. While ABX-ing, if you switch quickly between the tracks by pressing 'q', 'w' and 'e' - quite often (but not always) the selection won't be played from the very start.

Do you use the Java Sound Engine or a native output device?

Ah - thanks! (Did I miss that recommendation somewhere?)

Can't seem to reproduce it when I use Java Sound Engine.

That wasn't a recommendation. Actually I'd recommend against using the Java Sound Engine, since, well, it sucks. Anyway, the problems you describe shouldn't occur either when using native output. Maybe twiddling with the buffer size will help. Otherwise, could you please describe in more detail how to reproduce these problems? Thanks.

Ok.

I tried changing the buffer size, and it seems to directly affect how far in playback will start when switching between samples. More details in a PM.
