Hi Everyone, I intend on using the NANO 33 BLE to record sound and save it to an SD card. I have been looking at the inbuilt PDM library to work with this board but then, its more of analysing the raw ADC samples. https://docs.arduino.cc/learn/built-in-libraries/pdm How would I modify the code such that i can save actual audio samples e.g. .WAV files onto an SD card, any help rendered will greatly be appreciated, thanks.
