Hello forum,
Just joined here since I recently purchased a Audio Shield Rev. D for my Teensy 4.0.
I went over the tutorial video: Audio tutorial
The plan is to work with FFT and peak detection to run two stepper motors to synchronise movement of some optical filters to music. At the moment, I'm just trying to familiarise myself to the interface. I don't have buttons and potientometers at hand to try the oscillation-sketches, so I can't confirm that the oscillator sounds correctly, but the "beep" sounds normal.
Grabbed a quick audio recording of my headphone. Hope you can hear that Steely Dan is not supposed to sound like that, go listen to "Don't take me alive" for reference.

Everything else is normal, Teensy is simply powered by USB and nothing else is connected. I'm not using the highest quality SD-card, but that can't be it. I soldered the headers myself. The plan later is to work with line-in sound. But I'm off to a rough start...
