I'd say the implementation depends on what the user is trying to do.
Complete WAV data for a typical song could easily reach over a million
data points. Even with text compression that would make a pdf file a
worse choice than using the Win32 API functions to create a Device
Context and populate a bitmap. If the user doesn't need every sample
or just needs a few seconds of music then the graph as a pdf file can
be smaller than an equivalently sized bitmap. Plus, does the user
require pitch information?
