editing & combining sound files?

[Nicolas Cueto]

Hello List,

I wish to automate a repetitive (and tedious!) process that's now being
done manually using a sound-file editor (Goldwave).

The process is:

1. Open an AU sound file.
2. Append 1 second of silence to that file.
3. Open a 2nd AU sound file.
4. Copy and append that 2nd file to the 1st file.
5. Save as MP3 with a new title that now-modified 1st file.
6. Close that 1st file unmodified.
7. [Repeat 1-6.]

If this is possible (easily possible!) with LC, what LC commands ought I be
studying/using?

Many thanks.
