Adding more channels does nothing to the overtone information. From what I can find[1], it seems that the phase of the 25% and 75% waves are such that the two waves are actually inverse of each other. I don't know much about Gameboy hardware though. Do you actually know what the point of this is?

- magicalhippo 2y agoSure, but having a channel with 25% duty cycle of frequency f and a channel with 75% duty cycle of frequency 3f will lead to a different waveform after mixing compared to 75% at f and 25% at 3f, no? Depending on how that's processed downstream it could sound very different I imagine. In crude ASCII art (two inputs mixed to an output): ---_________ ---_---_---_ ¨¨¨_---_---_ vs --------____ -___-___-___ ¨---¨----___
- recursive 2y agoI saw a video a few years that provided pretty convincing experimental evidence that's not actually the case. https://www.youtube.com/watch?v=Ffka-hPzug0 https://www.youtube.com/watch?v=Ffka-hPzug0
- magicalhippo 2y agoVery interesting, though any non-linear effects would definitely get affected. Not sure how much that comes into play on the Gameboy though.
- charcircuit 2y agoIf you play 2 inverse waves it will sound different than 2 of the same wave.
