Hi,
I am trying to use a Teensy 3.6 as a soundcard (essentially along the lines of the PassThroughStereo and WavFilePlayerUSB examples), this works perfectly fine at 44.1 kHz for both recording and playback but I would like to run it at 192 ksample/sec. I have tried to use Frank B's sample rate change code but when playing back it seems that the PC still outputs at 44100 sample/sec but the Teensy expects 192 ksample/sec leading to weird sounding audio. When recording and running an FFT on the recorded samples, I can see a clear lowpass characteristic, cutting off at 22050 Hz so something is not in order. Any clues appreciated!
