Hi peeps,
Based on this project I've made my own repository
with added functionalities (and modernisations to be compliant with modern browers, mainly Chrome).
Added options;
Record the audio from your live performance.
Choose a sound file instead of the microphone to add effects to.
The project: https://github.com/jonathanneels/Audio-Input-Effects
Test it here: https://liveaudioeffects.herokuapp.com/
Enjoy!
