Hi Laura,

I just looked at your file and can confirm that there is indeed no clipping=
, but unfortunately mp3 compressing artifacts. I'm sorry about that.

We discussed such lossy audio compression artifacts on this list many years=
 ago. At that time I created a page that tries to explain what can go wrong=
 with mp3 or ATRAC : http://www.avisoft.com/compression.htm

Raimund
