Fast Synthesis of Basic Oscillators
Summary
Fast Synthesis of Basic Oscillators explores implementing fast oscillator signals on constrained hardware (GBA and rp2040) using 32-bit integer phase math, with walked-through examples for Saw, Square, Triangle, Pulse, and a parabola approximation of a sine. It discusses aliasing, potential fixes like PolyBLEP, and trade-offs between speed and audio quality, including code snippets and assembly hints.
