To use this library, open the Library Manager in the Arduino IDE and install it from there. Must see FFT Spectrum Analyzer 8-64 Channels ESP32 diy. Real time audio data analysis volume, FFT, pitch detection etc. Tom Nardi December 10, 2020 We probably don&x27;t need to tell the average Hackaday reader that the ESP32 is a powerful and extremely flexible microcontroller. Our microphone records voltage level representing the air pressure at a given moment. Hence we are anyway loosing precision in the grouping process.
