Printing at the audio rate would produce a *LOT* of numbers, but if a
lot of numbers is really what I want then printing at the control rate
with printk2 is usually good enough for my purposes.

Check out printk, printk2, and sprintfk... maybe one of those will do
what you need it to.

You can also use rms and printk2 to get amplitudes.
