Audio for ISF Shaders

ISF shaders in general know audio and audioFFT inputs which allow very sophisticated audio visualizations.

The problem is that Magic does not offer any module which outputs audio.

I think adding a media module "Audio" (similar to the "Image" module") which provides an audio output would open a whole new world for GLSL shader visualizations.

Remark: I guess (but don't know) that Magic's ISF module does not care what kind of data is passed to the loaded shader. If I'm wrong there's more work to do there obviously.

I know the AudioToImage module, but wasn't aware that the "Waveform" output is pretty much what I need. The "ToImage" part of its name was misleading me.
For whatever reasons in my tests I always had "Spectrum" checked as well, and of course the result was always different compared to the results I got using a 'normal' ISF-Editor. That's why I thought it wasn't possible.

Thanks a lot for the clarification!
