I tried changing the audio sample rate from 16K (which is working) to 22k and 44k - both without success. I just changed the #define AUDIO_SAMPLING_FREQUENCY but the generated WAV-Files which are saved on µSD-Card are not working properly and the length is not correct.
Any hints on how to change the sample rate properly to more than 16 k ?

I just figured out that changing the sample rate down to 8k is working . But increasing to more than 16k is not possible so far ...
