Does anyone think it would be possible to modify the real time pitch shifting program to shift the audio up? I saw somewhere that it couldn’t shift the pitch up, but it seems that this project accomplishes it:
Is there some difference between the microcontrollers that makes it so it only works with the ATtiny? I’m too much of a programming noob to figure out how to make the pitch shifting code in the link above work with the audio hacker library.
they both seem to use buffers, but whenever I try to change too much of the code I just get this really loud buzzing noise.
