[Asterisk-Users] mp3player - sounds terrible

[Yves]

I tried for the first time to use mp3player(toto.mp3) in my 
extensions.conf. This part
works perfectly.

But the sound quality is terrible. I tried to play the mp3 with mpg123 
on my audio device,
plays ok. And I cannot found any information about the mp3player 
application.

Do I need to encode the mp3 at a particular bitrate ? Does someone had 
this problem before ?
