For comparison, I've now rerun my test on my Athlon at home, and have obtained very similar results. I expected a bit of variation in the times, but what I didn't expect was a difference in the compressed output FLAC files, since the input WAV file was the same in both cases. This means that the same executable (FLAC 1.1.4) gives different results depending on the processor that it runs on. The obvious question is, if I expand the files back up to WAV, do I get the same original file in every case. That's my next test.

It's also notable that compression level 3 gives consistently less compression than level 1 - a bug in the compressor perhaps? I suppose I need to test this with some different CDs to be sure. -- chill ------------------------------------------------------------------------ chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=34156 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
