Hello,
I would like to do an envelope follower. The goal is to get the envelope of an audio signal to modulate filters.
I can't figure out precisely the way to do it. Here are my idea at the moment :
- read the audio input and extract positive peaks
- averaging / filtering
- inject result to modulate a filter
I use Teensy 3.6 + audio shield.
How is it possible to make readings of the audio input ? I know about audio library objects. But how to access directly to audio samples values for your code ?
I think I need some guidance !
