Hi,

What audio processing tools are out for Linux and are accessible?  I'm 
aware of sox, the various encoding tools (transcode, ffmpeg, et) and 
ecasound, but none of those replace the power of Sound Forge under 
Windows, at least that I've seen, although I could be missing 
something.  I have tried to figure out ecasound but didn't get anywhere 
with it.  I have files in mono that I want to convert to stereo for CD 
burning but I couldn't figure out how with sox, even after searching 
through the man page and reading the help.  I ended up doing it with my 
old Sound Forge but I would like to move more of my audio work to Linux 
if possible.  Here's the command line I used for sox after reading the 
man page:

sox -c 2 file1.wav file2.wav

I thought maybe I need to "mix" the audio, but I want both channels to 
be identical to the one mono channel in file1.wav.  I would like some 
general pointers to audio tools in Linux and tips on using them.  I'm 
running Debian and have added debian-multimedia to my sources.list.  
I've searched for various keywords but feel like I'm missing something.  
Any tips on getting started with ecasound would be appreciated as so far 
I haven't got it to do anything including loading or playing a file.  I 
would prefer text mode and curses programs now as I don't have enough 
memory to run X.

Thanks all for any help, ideas and pointers.
