Hi there,

There are two interesting tests on ATRAC3

1: http://www.sony.net/Products/ATRAC3/tech/lab/
http://www.sony.net/Products/ATRAC3/tech/l...test_report.pdf

2: http://www.rjamorim.com/test/multiformat128/results.html

The signal analysis in the ITS report suggests ATRAC3 being far superior to mp3 and wma, whereas the subjective listening tests in test 2 suggest it is the worst.

Can signal analysis be relied on, when it comes to subjective perception of audio signals ?
Is it possible, that a bad codec colours the sound file in such a way, that it actually sounds better but not authentic ?
Perhaps a good codec should not sound good, but reproduce in a transparent way. What do you think ?
