Sample-Free Drum Synthesis in Web Audio — Building Kick, Snare, and Hi-Hat from Oscillators in 60 Lines

Most drum machines on the web load .wav or .mp3 samples and play them back. That works, but you can also synthesise every voice from OscillatorNode , BufferSource -as-noise, and BiquadFilter — no audio files needed, no fetch wait, instant click-to-play. Here's a 16-step drum machine where every voice is built in code (≈20 lines each), plus the acoustic reasoning behind why the recipes work. 🥁 Demo : https://sen.ltd/portfolio/drum-machine/ 📦 GitHub : https://github.com/sen-ltd/drum-machine Thre
