Hi Jean Marc,

I was very impressed by the comparative results. Could you give a bit 
more information about what really are 7kHz and 3.5kHz in the 48kHz table?

I am looking forward that this will bring a bigger separation between 
the basic tools and speex in a sense that the basic tools could be used 
with more than one codec. I even understand that there is interest in 
the tools alone (Echo supression, ressampler, Jitter buffer, VAD,...)
