cleaning up audio recording

[John Schmidt <jaschmidt@uofu.net>]

Hi,

I have managed to transfer some tape recordings to my computer.  The 
recordings are from a seminar speaker.  There is a great deal of noise on the 
recordings both from the audio equipment and from general background noise.  
Are there any good packages out there that would allow me to clean up the 
signal?  

I used the KRec tool in KDE to transfer the audio.  I was looking at the 
artsbuilder routines and it appears like you can do some signal processing 
with this tool.

I am not looking to make it perfect by any means, just clean up the sound, 
take out the hiss, and try to preserve the voice as much as possible.

Thanks for any pointers.

John
