STM32F4Discovery Audio Problem

Hi all,

I use the STM32F4Discovery Audio playback and recording example. I sound 1KHz from speakers and record the audio. The wav file I get is filled with click sounds.

Also if I modify the code and keep everything in RAM, export it to Matlab I see distortions in the waveform (though maybe the problem is write speed to USB Stick).

What could be the problem?

Thank you
