Quoting Ralf Mardorf <ralf.mardorf@xxxxxxxxxxxxx>:
I agree, an experienced tester btw. does know that the tests that can be done are limited. You can't do it 8 hours a day, after making a few tests, _nobody_ is able to listen in the most possible neutral way anymore, after a few tests the listening is biased.
You don't have to do the ABX audio test in an 8 hour non-stop session. You can do two test runs, go to sleep, do three more, go to a movie, do one more, play some soccer and then do the remaining four. And if you have golden ears each run shouldn't have to take more than 20 seconds or so.
Some time ago I ask a friend to burn me an original CD, but he didn't, he converted from MP3 and burned a CD. I didn't know that. I started playing and stopped it immediately, without knowing that it were MP3s.
We don't know the settings used to make your friend's MP3s so it's hard to say anything specific about that test case. He might have used "-b 64" or something.
As said before; there are MP3 encoders (at least many of the older ones) that produce lots of audible artifacts. Recent versions of lame happens to be among the ones that produces the least. If you can truthfully ABX my files then you're perfectly entitled to claim MP3s sound bad to you. At least we won't be able to say that *you* can't hear the difference.
