Hibiki

Music, ambience and effects, played into Discord from your own desk.

Hibiki is a free desktop app for Game Masters. Build a scene, join your voice channel, and the table hears the tavern, the storm, and the door slam, with no slash commands and no hosted bot.

Download Hibiki v1.4.0

Open source, MIT. You bring your own Discord bot token; nothing runs on anyone else's server.

Three sound layers around the party An illustration of three overlapping sound layers drawn as circles on a battle-map grid: Tavern Bard music in amber, Crackling Fireplace ambience in teal, and a Mug Slam effect in rose, with the Hibiki mark where all three overlap. Hibiki mixes all layers into one stream for the whole voice channel. Tavern Bard music · loop · 60 Crackling Fireplace ambience · every 0s to 2m · 45 Mug Slam effect · one shot · 65

Three layers, one mix. Everyone in the voice channel hears the same scene.

One scene, three layers, one click.

A scene is a soundboard. Press play and the whole thing starts; tap any effect when the moment calls for it.

Ambience
Loops that run under everything: fire, rain, chatter. Each one can also repeat at a random interval you choose, so the owl hoots when nobody expects it.
Music
One track at a time, looped or not. Switch to the boss theme and the bard stops mid-verse.
Effects
One-shot buttons. Door, mug, sword, scream. Big enough to hit without looking.
Your own volume
Every track has its own level and a master slider sits on top, so the fight can get loud without the rain drowning the players.

Three steps to a bot in your server.

Hibiki talks to Discord through a bot you own. Making one takes a few minutes and you only do it once.

  1. Create the application and copy its token

    Go to the Discord Developer Portal, click New Application and name it (Hibiki works). Open Bot in the sidebar, then under Token click Reset Token and copy it. Treat it like a password.

  2. Invite the bot to your server

    Open OAuth2, then URL Generator. Under Scopes tick bot. Under Bot Permissions tick:

    View ChannelsConnectSpeakMove Members

    Copy the generated URL, open it, pick your server and authorize. The bot appears in the member list, offline until Hibiki runs.

  3. Paste the token into Hibiki

    Start Hibiki, open Settings and paste the token. Pick a server and a voice channel from the sidebar, then play a scene. If you prefer env vars, DISCORD_TOKEN in a .env file works too.

Questions GMs ask first.

Why not Discord's own soundboard?
Discord's soundboard plays short clips, one at a time, with no loops and no layering. Hibiki runs a whole session: music, several ambience loops, and effects at once, mixed into one stream, and the entire scene switches with one click.
Does anything run on a server?
No. The bot lives inside the app on your machine with a token you create. Nothing hosted, nothing metered, no account with us.
Do my players install anything?
No. Only the Game Master runs Hibiki. Players sit in the voice channel and hear the mix.
How is it different from Kenku FM or Syrinscape?
