This was a fun one. Handmade Hero Notes, Day 9. Variable-Pitch Sine Wave Ouptut: https://yakvi.github.io/handmade-hero-notes/html/day9

• Generate a Sine Wave
• Debug Writing to the Sound Buffer
• Link Sound Pitch to User Input
• Bonus: The First Game Jam (especially fun because I dug out some old photos)

Also, I don't apologize for crappy graphs. Trying to draw sine waves using ASCII/Unicode characters never gets old.
