ElevenLabs sound effects for Hermes: one tool, elevenlabs_sound_effect, that turns a text description ("glass shattering on a tile floor", "90s hip-hop drum loop, 90 BPM") into an audio file, 0.5 to 30 seconds, optionally a seamless loop, and sends it to you in chat. Bundles a sound-design skill with a local ffmpeg script (trim, loudness, mono, loop fixing, game variation packs) and, in Hermes Desktop, an inline sound card and a sound library tab. Model, audio format and endpoint are plugin settings.

## Good to know before installing

Uses your ElevenLabs API key (ELEVENLABS_API_KEY, the same key as Hermes's ElevenLabs voice; a restricted key needs the Sound Effects permission); every call is a paid generation billed to your ElevenLabs account. Only the sound description and its parameters are sent, to api.elevenlabs.io (or the data-residency endpoint you set). Files are written to cache/generated/audio under the Hermes home and never overwritten. One Python dependency (httpx, already part of Hermes).

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `ELEVENLABS_API_KEY`), then asks whether to turn it on.

```bash
hermes plugins install elevenlabs-sound-effects
```

2. Said no? Turn it on later:

```bash
hermes plugins enable elevenlabs-sound-effects
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
