Rectifying a signal

Post by Krischu » Fri Jun 09, 2017 12:55 pm

Audacity 2.1.0


I have an audio signal of which I would like to retrieve just the amplitude in a kind as if I would rectify the signal to a half wave and then send this to a low pass filter. I'm just interested in the peak amplitude envelope.
How can I achieve this?
