Audio Recorder

Build a whismical audio recording device that features built-in effects. You can record an audio sample (20-second max) and play it back as a loop. During playback, you can change the pitch of the recording using a slider, and apply two effects: a reverb and a delay/echo using rotary potentiometers. This fun project demonstrates the audio capabilities of CircuitPython!

Portable Device

The 3D printed enclosure houses an Adafruit Feather RP2350, I2S microphone, I2S amplifier, NeoPixels, and a built-in speaker. The device is portable, powered by a recharagable 2200mAh battery.

Featuring three-colors, the enclosre is made on a 3D printer with multi-color capability to create elements like text, icons, and colored segments.
