If you're looking for locations and values of peaks in a signal block,
you can use pique~ to do that.  When I started out, I wrote an
external called maxval~ to do this, not realising there was one in
front of my face :)  I recommend writing an external as an exercise
anyway.  Chances are, you will eventually find yourself with some
function you want.  It's better to space out the heavy lifting than
doing it all at once
