Re: JAMin CVS commit - 0.97.03

It might be that this is "correct". When you make a connection to  
JAMin there is a sudden disconnect in the signal level which  
corresponds to a large impulse.

We could damp the audio input when connections are made, but that  
seems a little excessive :)

Is the jump enough to cause the peak tracking on the RMS meters to be  
wrong?
