Use this skill for sound and music in melonJS — loading audio, playing effects, background tracks, audio sprites, volume and muting, spatial audio, procedural tone/noise generation, and effects such as reverb or a compressor on the whole mix. Covers the mandatory audio.init format list, the directory-not-file src convention, playTrack versus play, the fixed listener and pixel-scale distances of positional sound, and browser autoplay unlocking. Triggers on: audio, sound, audio.init, audio.play…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Audio
## Two setup rules
```js
import { audio, loader } from "melonjs";
audio.init("mp3,ogg"); // 1. BEFORE preloading any audio
await loader.preload([
{ name: "cling", type: "audio", src: "data/sfx/" }, // 2. a PREFIX, not a file
]);
```
1. **`audio.init(format)` must run before any audio asset is preloaded**, and
lists the formats you actually ship. Preloading first throws
`target audio extension(s) should be set through me.audio.init() before
calling the preloader.` It returns `false` when no audio backend is
available, so it is worth checking. The format list defaults to `"mp3"`.
2. **`src` is a prefix, not a file.** The loader appends the asset `name` plus
each configured extension and uses the first that loads — so
`data/sfx/` + `cling` + `mp3` → `data/sfx/cling.mp3`. Passing a full filename
gives you a 404. A `data:audio/...` URL is the one exception: it is used
verbatim, prefix and extension skipped.
`audio.hasAudio()` says whether the browser can play audio at all, and
`audio.hasFormat("ogg")` whether it can play one codec — useful for choosing
the `init` list or hiding a sound toggle on a device with no audio.

How to install
mdr add melonjs/melonjs/melonjs-audio@sha256:2c664c54e3b6131fThe line at the top of this page pins the label git:20261102.8d1fb28, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
