There are mp3's and there are mp3'. Not all are equal.

My wave editor provides me two options when converting from wave to mp3:

1) Layer 3

2) Layer 3 - ACM

As far as I know, the ACM variety is better.

Layer 3 - ACM is the proprietary software of Fraunhofer:

I have converted WAV file to Layer 3 ACM (41,000 Hz/320 kbps), and played them on my car audio system (fortunately it plays MP3 files) and home system, and frankly I can't tell them from the WAV files. Maybe I'm too old to be able to tell.

PS - I think once males get past 20 years old or thereabouts, very few of us can tell the difference.
