sound q: is this possible?

[Hugo Vanwoerkom <hvw59601@care2.com>]

Hi,

I record streaming mp3 music with mplayer.

I use snd to edit the .wav file.

Then I convert it with sox to the right frequency and use lame to cut an 
mp3 file.

For the last few recordings I notice that the sound volume varies during 
the recording so I have to be lowering or raising the sound volume all 
the time: it is either to high so it distorts or too low, I can't hear 
anything.

Is there a tool that will avoid that? I can see the problem already in 
snd: either the sound waves are off the left hand scale that goes from 
-1.0 to +1.0 or they are very small.

What I am asking for may not be possible: I just listen to the music...

Thanks.

H
