ESP32 Voice Recorder Using I2S Microphone

In this project, we build a voice recorder using the XIAO ESP32-C3 and an I2S MEMS microphone. The interesting part of this project is that no SD card is required. The ESP32 captures the audio through the I2S interface and sends the recorded data directly to the computer through the USB serial connection, where it is saved as a WAV audio file using Python. This tutorial demonstrates how to configure the I2S driver on the ESP32-C3, capture high-quality audio, and stream it to a PC for recording. This method is useful for voice logging, IoT audio monitoring, and speech recognition projects. ********************************************************************* Download code and circuit diagram: https://github.com/theinfoflux/ESP32-Voice-Recorder-Using-I2S-Microphone ********************************************************************* 💖 Support my projects on Patreon https://www.patreon.com/cw/theinfoflux Contact us: [email protected] #esp32 #esp32c3 #esp32projects #arduino #electronics #iotprojects #embedded #microcontroller #maker #diyprojects #i2smicrophone #audiorecording #voice_recorder #pythonprojects #engineeringprojects
