Im experimenting with Chops as a audio synthesizer. Thanks to the post by Fabricio Chamon on Youtube explaining how the ChOPS oscillator chop can be use to generate all the notes on a piano. He explained the base frequency formula 261.63 * pow(2,(0/12)) which produces the note C. I used this basic concept to generate synthetic audio with CHOPS.
On the SOP side a attributewrangle vex code block below created a animated attribute which controlled the audio amplitude via a geometry Chop node and the rectangle rotation in this movie
this is the code ... it makes a flattened sin wave
float sinflatten(int currentframe; int cyclelength; float flattenamount){ // currentframe is an integer // cyclelength is the number of frames in the wave cycle // flattenamount range is float 0 to 10 float bsquared = flattenamount * flattenamount;
I want to develop a more complex algorithm for deciding which piano note to pick per pixel so it's more in sync with the picture and the sound is more "other worldly"
a picture is a thousand words and maybe it's a thousand notes too
Here is another example of my latest CHOPS network that now scans multiple rows of pixels and uses hue saturation and luminance per pixel to generate audio .wav files.
It ain't pretty but it sounds that way.
I'm coining a phrase to describe the potential
A picture is worth a thousand words and maybe 1000 notes too
Did you ever check HMT houdini music toolset ? some really nice tool to make music from Houdini all CHOP based; https://vimeo.com/536214871 [vimeo.com]

Yes I've been looking at Andrew Lowel's posts and the sounds generated by his approach are awesome. I actually downloaded the HMT package and started playing with it a little. The thing is I wanted to generate audio .wav files directly. Then I found Fabricio Chamon's post on using the oscillator chop. https://vimeo.com/343143856 [vimeo.com] Its more down on the metal. Not as elegant a sound quality but still interesting and has many possibilities.
