Here is a component that uses some of the new audio OPs to select 3 frequency bands of an audio feed and output an amplitude channel for each.
It takes a built-in audio track for testing, or audio from an input device, or you can attach an CHOP containing audio to its input.
Works with 088 build 30580 or later. Extracted from the next Mixxa. Feedback appreciated.
