I'm more a Jitter user than an MSP one and I searched the forums but surprisingly I couldn't find any "simple" information on this.

I need to synthesize a sound from it's spectrogram. So to say, I slice a row of pixels from an image, convert it to grayscale (and in case to a list) and than feed it to.. ? Is there such an object which recreate a sound starting from its "composing frequencies"? If that make sense at all..

Hello,

maybe not exactly waht you are looking for, but I've been doing something like this...

Not sure if it's the right solution, but you could experiment with oscbank~ by mapping pixel values to frequencies of individual oscillators. If you have lots of pixels this would of course eat up your processor capacity, but you could give it a try.

Grazie Giorgio, nice patch, but I can't really get why (and how) ImageSonifyer use the pink (or white) noise to generate the sound. My limit.

Thanks Benjisugar, yes oscbank˜ seems the way to go. I finally found this as a starting point.

Still exploring the patch though..


Also check the "forbidden planet" patch in the Examples/fft-fun folder for a subtractive synthesis method based on FFT.
