Yea I never figured out how to reduce the white noise. I tried variations of sample rates in both my code and wav file.JaredTS486 any progress resolving your white noise popping issues? I haven't had a chance to try the tinyS3 in my older setup.
Using the "viola" example wav from a progmem did not have the same issue so I was wondering if maybe it was due to my method of converting the file.
When I try to use littlefs with my board I get severe errors that cause the board to get stuck in a boot loop. Pretty sure I am doing it right; I was able to play files via littlefs in the same way using the Pico. I might revisit this later.
Overall, after closing everything up, even with the volume maxed, I could barely hear the actual tricorder audio let alone the white noise. If there is some science to getting the sound to resonate with the tricorder to make it louder without drilling / adding holes for the speaker I could not find it.
I was also never able to get the low power mode on my board to work properly and there is still a 1-2 second delay where the screen is white before changing and the sound starts to play. I might try a different board at some point.
I ended up running out of time and used what I had. I'll add pictures at some point.
