Hey there!

I'm trying to convert noise into Color via Color Panel, but it's not behaving in the way that I expect. This may be an issue with Color Panel, or it may just be an issue with my process.

I've taken white noise and converted it into 3 frequency bands. I fed those bands into Color Panel, and it blinked a bunch. I fed just one band to it, and it blinked a lot, but moving the sound through the inputs, it's like it forgets what the "off" color was and just puts the most recent color to "off". So for example, I have it blinking between red and blue right now with only 1 input just by moving the signal between inputs.

I read that it takes CV, so I thought maybe feeding it audio isn't the correct approach? So I tried to find ways to convert the volume of the signal into voltage, but the only thing I knew to try was a converter, so I took an Analog to Digital converter and this happened:

It looks cool, no doubt, but I was expecting the output to be white. Is this a bug or is my process totally off?
EDIT: The gif has way less frames than I expected. On my computer the colors update way faster.

Thanks!

Not sure I understand what you mean by "off" color? Do you mean the color displayed when there are no input wires connected?

For the panel to be white, with the default settings (HSL mode, -5V to +5V range), the 3rd input (the 'L' input) would need to get a constant +5V signal.

Where does the expectation for the output to be white come from? Is it because of the white noise audio source?

In the screenshot, it looks like the input signals are essentially random at or near audio rate. The color panel is only going to update at screen/frame rate, so it is just flickering between the random colors indicated by the inputs sampled at the gui refresh rate (for ex, 60fps).

Do you mean the color displayed when there are no input wires connected?

Yes, so essentially I can make it go from switching between on and off (red to black, for example) to switching between red and purple, or any other color combination, I believe.

Where does the expectation for the output to be white come from? Is it because of the white noise audio source?

Yes, in a way. Since I'm using RGB mode, I was expecting sending in a sound source at full volume to each input would give each color value (R, G, and B, respectively) 255. And of course, 255, 255, 255 is white. But as I mentioned, I figure it's very possible that my method of converting volume into a signal readable by Color Panel is invalid. And all of this is assuming that each input corresponds to a specific color (first one is red, second is green, third is blue, for example)

If you have any ideas in that regard, please let me know! ^_^
