Raspberry Pi I2S Stereo Microphone Analyses in Python
A simple MEMS I2S microphone and audio processing library for ESP32.
ESP32 sound meter with multiple INMP441 MEMS microphones
Code snippets showing how to record I2S audio and store as .wav file on ESP32 with SD card, how to transcribe pre-recorded audio via Deepgram SpeechToText API, how to generate audio from text via TextToSpeech API from OpenAI a/o Google TTS. Triggering ESP32 actions via Voice.
Example of using an INMP441 microphone with ESP32 over WiFi
An example of recording audio onto a MicroSD card, using an INMP441 microphone and a XIAO ESP32-C3
Raspberry Pi Pico (RP2040) playground
Wakeword Detection using INMP441
Two state sensor (On/Off) reacting on sound levels measured by I2S microphones ( SPH0645LM4 or INMP441 )
This project's aim is to calculate localized coordinates of a sound source using three ESP32 microcontrollers and digital microphones.
Add a description, image, and links to the inmp441 topic page so that developers can more easily learn about it.
