dsh-finish-sound

DSH Web UI plugin that plays a short cue when a turn finishes, and a different cue when the agent asks you something.

• Two events, two cues. A finish cue plays when a turn ends in any session, not only the one on screen. Subagent turns never ring the finish cue, so one parent turn rings once however many delegates it runs. A question cue plays when ask_user_question or an approval starts waiting for you. A run of queued turns only rings once, at the end.
• One setting for every session. Settings → General → Event sounds turns both cues on or off for this browser, sets the volume and previews either cue.
• Your own sounds. Either cue can be replaced with an audio file of up to 2 MB and 10 seconds that the browser can decode (WAV, MP3, OGG, …). The file stays in this browser's IndexedDB; Use built-in returns to the shipped clip.
• Generated clips. Both cues are WAV files generated with MOSS-SoundEffect-v2.0 (Apache-2.0) and ship inside the plugin, so they play offline.

Cues

Event	Sound	Clip
Turn finishes	Two bright marimba notes one step apart	assets/finish.wav
Agent asks	Two quick bright marimba notes going up, higher and softer than the finish cue	assets/question.wav

Exact prompt and seed for each clip are in CLIP_PROVENANCE in lib/sounds.js.

Install

Use the DSH plugin manager (Plugins → Add plugin) with the spec:

github:mkpoli/dsh-finish-sound

Or install from the command line and add the bundle to the profile:

dsh plugin --profile web add github:mkpoli/dsh-finish-sound

Then add "dsh-finish-sound" to dsh.profile.bundles in ~/.dsh/profiles/web/package.json and restart dsh web. The package ships cordis.patch.yml, which inserts the loader entry; the browser half loads through the package's dsh.client declaration.

A prebuilt tarball is attached to the release:

dsh plugin --profile web add https://github.com/mkpoli/dsh-finish-sound/releases/latest/download/dsh-finish-sound.tgz

For a local checkout, link:/path/to/dsh-finish-sound works the same way.

Behaviour

• Browsers keep audio locked until the page has had a user gesture. A cue that fires before then plays on the next click or key press unless a new turn has already started.
• A snapshot that ends a turn and asks a question at the same time plays the question cue only.
• A subagent Session never rings the finish cue. The parent turn rings once, when its own turn ends.

Development

npm test        # clips, generated catalogue, bundle freshness
npm run build   # regenerate lib/sounds.js and lib/client.js from assets/ and src/

The browser bundle is generated. Replace a clip in assets/, edit src/client.js, then run npm run build: lib/sounds.js embeds each clip as a data URL and lib/client.js registers the plugin module and that catalogue in one file, because the client module loader resolves only modules a bundle registered.

The clips were generated locally with MOSS-SoundEffect-v2.0 from the prompts and seeds in CLIP_PROVENANCE (the seed goes to the pipeline's seed argument), then mastered: 30 Hz high-pass, trim, fades, peak normalization, mono PCM16. The question cue is set to 80% of the finish cue's RMS.
