How to connect a spectrum analyser to Overtone Output?

[nicolascepeda]

hi everyone, I recently started playing around with overtone and so far loveing it! I am specially interested in developing Synths, in order to do so, seeing the frequencies visually is very helpful. So far I haven't found anywhere an example/docs/code snippet/etc that shows how to do this.

Could anyone give me any hints? Thanks a lot and sorry if i posted this in the wrong place!

Short update, found this project which seems to solve exactly this issue https://github.com/overtone/shadertone/blob/master/examples/spectrograph.clj

Sadly the last update was 8 years ago and runs on clojure 1.6.0 which makes it impossible to use. Will post an update in case I manage to make it work

If you connect to an external server you can add something like this to your boot script:

s.waitForBoot({
	 {In.ar(0)}.spectrogram;
});
