Please have a look at either of these.

The I2S Output Sample demonstrates how to use an I2S driver to send an output stream of audio data. The sample sends a short burst of audio data, consisting of a sine wave.

The ArgonKey Board Microphone Sample provides an example of how to acquire audio through the on-board MP34DT05 microphone. The microphone generates a PDM stream which is acquired through I2S.

The I2S Echo Sample demonstrates how to use an I2S driver in a simple processing of an audio stream. It configures and starts both the RX and TX streams and then mixes the original signal with its delayed form that is buffered, providing a simple echo effect.

The X-NUCLEO-IKS02A1 Shield - MEMS Microphone Sample provides an example of how to acquire audio through the digital MEMS microphone on X-NUCLEO-IKS02A1 shield. The microphone generates a PDM stream which is acquired through I2S.

Please refer to the respective links for more detailed information on each sample.
