The title says it all. I'm thinking about creating/manipulating sounds using visual tools. It would need some modules to convert sound, bitmaps, graph-data in any direction and suport bitmap manipulation
Example usage:
- feed fft data into bitmap
- process bitmap (multiply with other bitmap,...)
- convert back to sound (ifft,...)
As an easy start how about a bitmap get RGB-value at module to drive an additive oscillator using RGB values of a bitmap (à la metasynth, coagula).

My friend at uni. did something along those lines for a project, converted audio file into FFT data (visually) then used image processing techniques to modify the image before converting back to time-domain audio data 🙂
Would be interesting to try this in SM if/when we have the necessary tools!

I requested this ages ago and it might be on the list somewhere, i also requested text to speech which might be more simple to include as theres dev packs to add it to software, that would be great for testing effects such as vocoders and chorus ect.

Also something like ARGB to poly and mono would be cool, i dunno what it would be like though in terms of waveforms it creates.

It depends. Coalgula for example uses the red colour value for left channel amplitude, green for right channel amplitude, blue for smearing (adding noise), other convert to grey-scale and use the brightness value for spectral bin amplitude

Coalgula is a cool program, i remember using it a while back, not sure if its been updated recently though.
