Transcoding lossy->lossy degrades the quality, even with the same PAM. Layman's explanation--the orginal encoding takes waveform X and converts it into waveform Y (which should be very similar to X, but nevertheless different). Transcoding takes waveform Y and converts it into waveform Z. Z!=Y BECAUSE Y!=X. If you're starting with a different waveform, there's no way you'll end up at the same place after the transformation. Having a different PAM can definitely aggravate the differences though. I'm surprised the OP thinks there's something wrong with not hearing a difference at 320kbps though. Aside from a few killer tracks and artificial samples which are fairly unlikely to be in his collection, if he could hear the difference, he'd be the first. -- CatBus ------------------------------------------------------------------------ CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=39112 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
