Maths extracts an amplitude envelope from audio by using Signal IN with adjustable FALL ballistics

Procedure L2First instrument E · Modular, Eurorack, grooveboxes & dawless

To use Maths as an envelope follower, patch an audio or modulation signal to CH.1 or 4 Signal IN, set RISE to noon, and adjust FALL to control how quickly the envelope decays between peaks. Signal OUT provides positive and negative peak detection; OR bus OUT gives a more typical positive-only envelope follower output. Short FALL tracks rapid amplitude changes; long FALL smooths them. No external rectification is needed.

Examples

Audio signal → CH.1 Signal IN. RISE at noon. Adjust FALL for desired response speed. OR OUT → modulation destination for a conventional positive envelope follower.

Assessment

What is the difference between taking the envelope follower output from OR OUT vs. Signal OUT, and what FALL setting gives the fastest response?
