@debuffjp/audio ​

A small Web Audio facade: music and SFX buses, autoplay unlock on the first gesture, buffer playback with pitch variation, and an asset-free synth for placeholder or stylised SFX. No dependencies.

ts
import { Audio } from "@debuffjp/audio";

const audio = new Audio();
await audio.decode("coin", assets.audio("coin"));

audio.play("coin", { volume: 0.8, rateJitter: 0.05 });
audio.synth({ freq: 660, freqEnd: 220, decay: 0.15 }); // no file needed
audio.volume("music", 0.5);

API ​

  • decode(id, arrayBuffer), has(id)
  • play(id, { bus, volume, rate, rateJitter, pan, loop }) → Voice
  • synth({ wave, freq, freqEnd, attack, decay, volume, bus }) → Voice (wave: any OscillatorType or "noise")
  • voice.stop(fadeSeconds?)
  • volume("sfx" | "music" | "master", value), unlocked, ctx (the underlying AudioContext)
