Reminds me of the Anthem spreadsheet software in Douglas Adams' novel, Dirk Gently's Holistic Detective Agency:

"But the silliest feature of all was that if you wanted your company accounts represented as a piece of music, it could do that as well. Well, I thought it was silly. The corporate world went bananas over it."

"The yearly accounts of most British companies emerged sounding like the Dead March from Saul, but in Japan they went for it like a pack of rats. It produced lots of cheery company anthems that started well, but if you were going to criticise you’d probably say that they tended to get a bit loud and squeaky at the end. Did spectacular business in the States, which was the main thing, commercially."

Super cool idea but I tried a few profiles, they all pretty much sounded the same. Maybe needs a bit of randomness with the username as a seed or something.

The problem is one in the same with volume: identical frequencies in the same week result in constructive interference leading to a louder tone, which drowns out the others. I need to set the gain such that the max for any one frequency is 0.1 per week.

I agree it could use some randomness. To maintain harmony, however, I've made each note a perfect 5th of eachother. Maybe I could adjust the ratio to make perfect Nths instead.

Love it! I agree though, it needs some more factors to make various Githubs different.

ignore the warning about lowering the volume at your own risk.

Sorry! I set the gain to 1/10th of default but if several of the same tones are being played at once it's a bit loud. What I should do is reduce the gain on each subsequent oscillator of the same tone.
