[Asterisk-bsd] Music On Hold, working with FreeBSD 5.3

[Chris Stenton]

You don't neeed to sample down mp3 files to use format_mp3 infact they will 
sound better if you don't. If you are going to sample down you might as well 
convert them to slinear at the same time to reduce overhead.

Is there some old documentation around still cos it was a very early version 
of mp3_format that was fixed format?


A bit late now but what mpg123 thread problem were you having I thought I 
fixed that months ago on 5.2.1? I am running 5.4-stable now and cvs-head 
seems rock solid at the moment.
