Before we upload the code, we're going to add two lines of code (as highlighted in the image below). The first line is going to adjust the volume, which we add after we initialize the I2S output ( out = new AudioOutputI2S (); ). High-Speed ADC Sampling Using I2S and DMA. Using the ADC directly is fine for low frequency and one-off sampling. For sampling high-quality audio data you will need to be sampling at 16-40KHz (watch the first video for some nice animation on this!). You can do this using a timer, but it's not the best use of the ESP32's CPU resources.Nov 17, 2021 · First of all, thank you for your wonderful teaching, tutorials, examples and libraries. I’m trying to use a I2S MEMS ICS43434 mic and a AMP MAX98357A on a esp32 dev kit using your audio tools streams i2s to i2s. But I’m having some trouble configuring the two boards using the example provided. I installed the board using different pins as ... 2020/06/11 ... アナログマイク.
