That's just... not true at all. First of all, I personally have taken a fair number of ABX tests. Some I "passed", some I "failed". One thing I learned very quickly is that it's pretty easy to THINK you hear a difference, and then fail to be able to identify it blind. But after a while, you start to get a handle on when you really hear it and when your mind is playing tricks on you. You can download free software that's very easy to use and will let you ABX two files. I spent some time doing that comparing different lossy compression algorithms and bitdepths. From that experience alone, I can say it's absolutely not the case that "EVERYTHING" vanishes. Quite the contrary, it's very easy to hear differences at low-ish bit rates. Second, there's an entire body of hearing and psychoacoustic scientific literature in which blind hearing tests are a basic tool. Did you think the last century or so of careful research on that topic was conducted using sighted tests? -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=86419 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
