It is easy to convert 16bit PCM to PDM, if not oversampling the PCM data.
That is, if the wav file contains 64K audio samples, convert the 64K audio samples to 64K PDM samples is no issue.
However, without oversampling the 64K audio samples to at least 64 times, the output 64K PDM samples is pretty much useless.
I am working on PDM to PCM conversion too.
Have trouble to test my code using existing PCM/wav file as input source.
Looks like the only way to test my code is get real PDM samples from digital microphone.
Any suggestion besides to use the real PDM samples from digital microphone?
