Recording audio with the X-NUCLEO-CCA02M1 Expansion Board¶
This application provides a simple example of usage of the X-NUCLEO-CCA02M1 MEMS Microphones Expansion Board.
It shows how to record a 2-channel stereo signal as an array of PCM samples that can be acquired through an audio SW like Audacity, for example.
Microphones configuration
Currently the only configuration supported is 2-channel stereo at 16KHz, with in fact only one microphone acquiring audio data while the other being silent.
