[NCLUG] audio cd recording strangeness

[Daniel Miles]

I use
cdrecord -v dev=whatever -audio -pad *.wav

The pad is this very strange thing that I don't really understand but it
comes down to: tracks on an audio CD have specific increments of length
such that if you have a track that takes up the wrong amount of time you
have to pad the rest of the block with silence.
