NEW LEARN GUIDE: I2S Microphones with CircuitPython #LEDs #AdafruitLearningSystem @Adafruit

Article excerpt

Starting with version 10.3.0-alpha.3 CircuitPython has added a new audioi2sin module on Raspberry Pi and Espressif based devices. The new module unlocks the ability for I2S microphones like the ICS43434 or SPH0645LM4H to be used in CircuitPython projects. This guide will demonstrate the new capabilities with 3 examples: A basic script to record audio to a wave file written to the sd card. Audio reactive NeoPixels that dance and glow with music. A voice changing microphone that applies effects to your voice and outputs the altered audio stream to a computer via USB. Read more at I2S Microphones with CircuitPython
