I did find a module called Audio::Wav that seemingly would take care of all this, but I can't find the module anywhere with PPM.

AFAIK the Audio::Wav::* modules are pure Perl so you should be able to install them using perl -MCPAN install Audio::Wav even if you don't have a C compiler on you system.

You might even be able to get away with copying the *.pm files to wherever you want them installed.
