It doesn't really matter about the type of music because that instrument positioning argument is pretty much pants. It's based on a misunderstanding of how joint stereo works, which is a bandwidth-saving technique employed primarily by lossy encoders, but also by some lossless encoders such as APE (this last bit is a clue to how much it impacts sound). These are some of the REAL artifacts of lossy encoding, in descending order of easiness to hear/obnoxiousness: - Warbling. Let's say you have a long sequence of rapid-fire percussive noises. Typically faster than drums, like applause and sometimes castanets. Each sound may be imperceptibly time-shifted, but collectively, it'll sound like the audience is clapping underwater. - Ringing. You'll hear this on brass instruments and piano, maybe others. It will just sound more metallic than it should. - Pre-echo. Another form of time-shifting. It basically makes percussive sounds softer. Like the drums have been stuffed with pillows. - Hissing, etc. There are lots of lesser artifacts that actually sound pretty natural, and you very likely won't spot them just listening to the compressed version. The only way you can really spot them is the carefully compare against the source, preferably in a double-blind test. Be warned that if you just do A/B testing, your brain WILL imagine differences between tracks, and your knowledge of which track is lossy will lead you to erroneously believe you've spotted a difference. Hope that helps. -- CatBus ------------------------------------------------------------------------ CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=51021 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
