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.

Hi

I made a panoramic video (using PTGui pro), which generated a 5500 x 768 .mov file

When I try using this in a sketch, it loads fine (no errors being shown) but it just doesn't display anything.
Is there some resolution limitation? Problem with memory perhaps? I've already upped the setting to the max but alas.

I've also tried getting the quality down, lowering fps, and such.. Doesn't seem to be helping. The file I just tried was 15fps and 1.9 Gb big. Running 4gb ram on a macosx 10.6, latest processing version.

I'll be trying this on a pc later today but its pretty important that it works on mac.

Any ideas? Much appreciated
