Hi All
TeensyLooper
An audio looper with reverse capabilities and low latency, reverb and based on the Teensy (4 and 4.1) platform.
This project is born out of the "need" for a simple audio reverse tool for my live setup. It will be connected to the AUX1 send/return bus on my console but the main use will be to record and reverse spoken words from old vinyl records. A unit that samples a few seconds of audio (mono) and reverses it playing it in loop mode.
The base is a Teensy 4.0 and it has a 4 second sampling time @ 44.1khz sampling rate 16 bit resolution. You can use a Teensy 4.1 that will increase the sampling time to 8 seconds.
First interaction:
one input one output Rec button Kill button Loop or single shot switch Reverse or forward switch
Code for 4 seconds To Do:
PCB
Front Panel
test reverb FX Code
Test add ons (second interaction)
Second interaction:
Added GATE/TRIGGER control for record and kill function Added Reverb FX (via code and Open Source Library) Added Reverb Size potentiometer Added Reverb WET/DRY potentiometer

Feel free to try it, hack it, change it. Any suggestions are welcomed and if you find bugs or improvements let me know :)
I'm no serious coder so i admit i used chatgpt for the coding part. Hardware wise it's pretty straightforward :)
Thanks for taking time reading this
