ESP32 Audio Input Showdown: INMP441 vs SPH0645 MEMS I2S Microphones!

We're back looking at some more options for getting audio data into the ESP32! It's worth recapping that video as there's some interesting stuff around sampling rates, DMA transfer and ADC calibration. In this video, we're going to be looking at a couple of boards with MEMS (Micro-Electro-Mechanical System) microphones. The two boards we're looking at are the SPH0645 and the INMP441. What's really interesting with these boards is that they integrate the audio amplifier, ADC and the I2S interface. So the output from the boards can be fed directly into the ESP32 without using the ADC. Once again we're taking advantage of I2S and DMA transfers to get the data into the ESP32. In the next video, we'll look at getting audio out of the ESP32, another small step to finishing my next project. Thanks for watching, and don't forget to subscribe! ---
