Possible lowest sound settings with winmm.dll mciSendString?

Question

I am trying to set this entry to the lowest settings using C # and winmm.dll. I set the settings below, but I do not hear the difference. Does anyone know if I missed something?

I am trying to get the lowest sound settings. As if you heard from a walkie-talkie.

Any changes I make for the sampling rate do not seem to take effect.

Thanks,

Answer 1

What is this record? If it is, try reducing bit-bit to 4, and you should be the difference here. If this is music, you should definitely hear the difference between 8 bits per sample and 16.
