Hi,

I did some normalization= of some mp3 files and on some got the warning:

sox WARN mp3-util: MAD lost sync

The resu= lting files seem to be ok, i.e. they seem to play from beginning to end (I = have the pre normalization version of the file for comparison)
Also, the resulting files are much smaller. Sometimes megabyte= s smaller.
Whats up with that?

And, does= normalizing an mp3 multiple times degrade the audio?

Mac
