2 ESP32 Audio Input Using I2S and Internal ADC
Recommended for sampling analogue audio on an ESP32 at high rates, by reading the internal ADC through the I2S peripheral with DMA.
3 Using I2S on the ESP8266 to drive WS2812Bs.
Pointed to as an example of using I2S and DMA on the ESP8266 to drive addressable LEDs without tying up the processor.
4 ESP32 Sound - Working with I2S
DroneBot Workshop's introduction is a recommended quick start for I2S audio on the ESP32, with a companion article and simple library for small projects.
5 #419 ESP32 Audio Tutorial with lots of examples
Andreas Spiess's video is treated as a leading resource on I2S audio with the ESP32, useful for judging what the chip can handle and for practical tips.
Hidden gem6 Color PAL Encoding
Cited as an impressive bitluni example of an ESP32 generating colour PAL video in software by using its I2S peripheral.
7 Coding a Sound Driver on the ESP32 ULP
bitluni's project is praised as a clever ESP32 hack that generates audio from the ULP coprocessor, and serves as a worked example of ULP programming.
8 ESP32 Audio Input Showdown: INMP441 vs SPH0645 MEMS I2S Microphones!
Recommended for connecting digital MEMS microphones to an ESP32 over I2S, including a timing quirk of the SPH0645 that the INMP441 avoids.
