[NCLUG] Music editing software

[John Gilmore]

Both square and curly actually. The square changes the speed a little, and
the curly ones double or halve the speed. The "-af scaletempo" is a filter
that prevents the pitch changes. It repeats or drops small sections of audio
instead. Since the pitch doesn't change it's much less obvious you sped
things up or slowed them down and makes the transition less jaring.

I'll apt-get install audacity and take a look at it, thanks.
