Hi,
I'm looking for ways to generate audio from a spectrogram.

Basically, this is what I want to achieve:

the functionality of that prog is great, if I enter a screenshot of a spectrogram (generated from a real song) it plays it back quite well.
But, for a project I'm doing I'd like to be able to do this directly in processing. Using saveframes manually won't work. Have there been any scripts written like this? Does anyone have a clue how I might start?
What I know so far is that its a 3d graph where x = time, y = frequency and whitevalue = level
So do I just go through this pixel per pixel and use minim to output that specific frequency at the specified db? I'm quite new when it comes to audiosynthesis so any advice is appreciated.
