Just checking -- are these plugins *before* Edcast in the chain of 
plugins?  If they're not, they won't have any effect.

Does it sound like this in yoru player or only on the stream?

It sounds like the MP3 data is being sent straight through to Icecast 
without being reencoded, which is of course not what you want.  This 
should only happen ifthere are files with differing sample rates or 
possibly different bitrates.  MP3 isn't really intended to deal with this. 
But as I say, it should be being reencoded after it goes through your 
other plugins.

I'm not very familiar with Foobar 2000 so can't comment on the specifics 
of your setup.  Maybe someone else can.
