This test takes two analogue audio signals and subtracts them. The resulting file is an upper bound on any difference - in other words any real difference between the two files will be smaller than the result. You can then listen to the differences without anything masking them. You can turn up the volume, look at the waveform, etc.
It's an EXTREMELY sensitive test - much more so than human hearing in an A/B comparison. For example phase differences will show up very clearly in the difference file even when they were totally inaudible in the original sound. If a negative result on this test doesn't convince you, nothing will and there's no point in doing ANY test. It's also far easier to do than a proper blind test. It's off topic, but you claim to have done blind tests for CDs versus CDRs - can you describe the test setup and results in detail? -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
