This application will control parameters for 16 oscilators in webaudio.

There is a tiny little trick to it.

The video feed gets resized to 16x11 so as to reduce it to a very finite amount of data.

While we have rgb data for all those 16x11 pixels, this example is very easy and we only use the general brightness of pixels.

We then use this very finite amount of data to choose the note and gain of the oscillators.

You can’t perform that action at this time.
