the default magnitude is not initialized properly which can lead to very
quite tones (inaudible actually), so i've set the default value to 100
(since that's about half way between the min and max). i also fixed up
the headers to pull in proper ones for prototypes and such, and touched
up the usage to document the -m option and more accurately describe the
-f flag.
