Waveform Generation

[rob-luke]

Is anyone interested in a package for generating common waveforms? Im thinking of something similar to MATLAB.

Or does this functionality already exist somewhere else? I figured this isn't overly complicated, but something we probably all have our own snippets for.

I made some not so elegant code a while back in https://github.com/gummif/Musical.jl/blob/master/src/synth.jl#L47
A submodule in DSP or a package with a nice API will probably be used by many.

I've currently got a SinSource that conforms to the SampleSource API, so you can read from it either a number of samples or number of seconds, e.g. read(src, 1024) or read(src, 100ms). I've found it to be a pretty handy API for generating an arbitrary amount of waveform data.
