Just create a function or lib of your own that does the sample generation
and then uses my lib to output them. I made the library as a base library
that other libraries can use and extend. For instance, I purposefully left
out a mixer capability, so that you have control over the mixing rather than
me. If you look inside my gameboy emu, you'll see I do additive mixing and
have audio do things like x frequency at y volume stay for z amount of time
(with freq. and volume sweeps, etc.). I purposefully let the developer have
control on his/her audio completely so that I do not restrict the
capabilities here, and so I don't have library bloat.
