Audio to CV

What it does

Audio to CV is a modulator: it makes a moving value that can drive any control on the canvas. It takes audio in and gives control signal out.

Try it

Feed a vocal or instrument track in and use the follower's output to pulse a Shape's scale in time with the performance.

Inputs and outputs

Controls

Every control with a range can be driven by a modulator, a note, an audio level or a sketch.
