I did some testing and found that I'm able to play multiple buzzer noises at once. I also took the liberty of converting all of the different note names to hexadecimal to make it easier for me to encode a short tune...
Unfortunately, I'm on a Mac, where I am unable to record my internal audio since QuickTime doesn't even support it. It can only record external audio. And I'm not the kind of person who would download alternate software just to be able to do it as they might not even be safe.
I got an idea that might just work... I'm gonna use my phone to record the audio, and the Mac to capture my screen. Then all I need to do is try and sync them up as best I can.
