You kick off a task, switch to your browser, and forget about the terminal.
Five minutes later you check back — it's been waiting for you the whole time.
Sound FX adds themed audio cues to Claude Code and Opencode so you never have to babysit the terminal again. Hear when a task finishes, when something breaks, or when the AI needs your input — even while you're in another window.
Pick a single theme or go Mix mode and let 12 themes collide randomly. JARVIS confirms your deploy. GLaDOS mocks your errors. Pikachu celebrates your tests passing. A WoW Peon reluctantly obeys your commands.

Platform Support
Works on every major platform. No extra setup needed for local use.
| Platform | Extra setup? | How it works |
|---|
| macOS | No | Plays via afplay directly |
| Windows (WSL) | No | Auto-calls powershell.exe or ffplay.exe via WSL interop |
| Linux desktop | No | Auto-detects paplay / ffplay / aplay |
| Remote server (SSH) | Yes | Requires a relay script on your local machine — see below |
Remote server setup
When running on a headless server with no audio hardware, sounds are forwarded to your local machine via a lightweight HTTP relay:
# ① Clone the repo on your LOCAL machine
git clone https://github.com/6m1w/claude-sound-fx.git
# ② Start the relay (runs in background, listens on port 19876)
python3 claude-sound-fx/scripts/relay.py &
# ③ SSH into the remote server with port forwarding
ssh -R 19876:127.0.0.1:19876 your-server
# ④ On the server, use Claude Code / Opencode as usual — sounds play locally
Relay commands:
python3 scripts/relay.py --status # Show config and loaded themes
python3 scripts/relay.py --kill # Stop the relay
Install
Claude Code
/plugin marketplace add 6m1w/claude-sound-fx
/plugin install sound-fx@claude-sound-fx
Then configure your theme:
/sound-fx:setup
The setup wizard will walk you through theme selection and trigger mode.
Opencode
npm install @6m1w/opencode-sound-fx
Add to opencode.json:
{
"plugin": ["@6m1w/opencode-sound-fx"]
}
Shares the same config file (~/.claude/sound-fx.local.json) and audio themes.
Update or Remove
Run the same command anytime:
/sound-fx:setup
The wizard will ask you to Configure, Update, or Remove:
| Action | What it does |
|---|
| Configure | Set up or change your theme and trigger mode |
| Update | Re-apply current settings, refresh hooks, and play a test sound |
| Remove | Completely remove sound effects — deletes config file |

How It Works
Sound FX hooks into 7 lifecycle events:
SessionStart ──→ 🔊 "I am ready." (theme: start)
UserPromptSubmit ──→ 🔊 "Understood." (theme: submit)
Stop ──→ 🔊 "Task complete." (theme: complete)
PostToolUseFailure ──→ 🔊 "That was a mistake." (theme: error)
Notification ──→ 🔊 "Hmm?" (theme: notification)
PreCompact ──→ 🔊 "Memory failing..." (theme: precompact)
SessionEnd ──→ 🔊 "Until next time." (theme: session_end)
Note: Tool permission prompts (the approve/deny popup) are not a hookable lifecycle event in Claude Code, so this plugin cannot play sounds for them.
