How to Build a Custom Soundboard for a Tabletop RPG Session
To build a dependable soundboard for a tabletop roleplaying session, sort downloaded music and effects by the moments you expect to use them, trim only what needs trimming, then load them into a player that can keep background tracks running while you trigger short cues. Test the complete audio route before game night. This guide uses OBS Studio as one practical option for a computer based board; the same preparation steps work with other local audio players.
1. Plan the board around table moments
Start with a short list of scenes and actions rather than collecting every sound you might conceivably need. For example, a cooperative adventure might use three ambient beds—travel, a busy settlement, and a quiet interior—plus a handful of one shot cues such as a door opening, a distant bell, or a creature’s arrival. A small set is faster to scan while you are also running the game.
Give each sound a clear job: bed for continuous atmosphere, transition for moving between scenes, or cue for a brief event. Decide which beds may overlap with cues, and which should stop first. This simple map becomes the board’s layout and helps prevent a dramatic cue from competing with music or dialogue.
2. Organize files before importing them
Make one folder for the session and subfolders such as Beds, Transitions, and Cues. Keep the audio files together in a stable location before adding them to a player; moving or renaming source files afterward can break references in some setups. Use short, descriptive names that explain both the sound and its intended use, such as Forest_Night_Bed or Stone_Door_Open instead of track-final-2.
If an existing filename is useful only to its original creator, preserve it in your notes or add a concise tag to your new filename. Avoid using filenames as the only way to distinguish nearly identical versions: audition them and keep the one you can identify quickly. This is an organizational recommendation, rather than a requirement of OBS.
3. Trim and export only when needed
Downloaded files may contain a long lead-in, a trailing silence, or more material than the cue needs. In an audio editor such as Audacity, import the file, select the portion you need, listen to the selection, and export that selection as a separate audio file. Audacity supports exporting a full project, selected audio, or a marked loop region; it also lets you choose the destination folder and format. Audacity’s export guide
For a straightforward compatibility check, OBS Media Sources document support for MP3, AAC, OGG, and WAV audio. If a file fails to load, convert a copy into one of these supported types and test that copy. Audacity describes WAV as uncompressed and MP3 as a smaller, lossy format; choose the format based on your player’s support and practical storage needs.

4. Choose a playback setup
For a simple in-person game, a regular audio player and a prepared folder or playlist may be sufficient if you can reliably switch tracks and stop them. For a session that needs individual cues and layered beds, a soundboard app can provide a more direct control surface. Check that the app supports the formats you have and can play the kind of overlap you need.
OBS Studio is an option when you want named audio sources and already use it for a virtual tabletop or call setup. Add a Media Source for each cue or bed, select Local File, and choose the corresponding audio file. Its documented audio types include MP3, AAC, OGG, and WAV. OBS also provides source settings such as looping and restarting playback when the source becomes active; use those intentionally, since a cue that restarts on activation behaves differently from a bed that should continue.

OBS has configurable hotkeys for actions such as hiding or showing sources, and its documentation describes these in the OBS Overview Guide. Bind only your most-used cues and playback controls, and check for conflicts with the game, chat app, or virtual tabletop. OBS Studio Overview Guide
5. Set levels for speech and music
Listen to each sound at the volume you expect to use, then compare it with someone speaking at the table. Music often needs to sit lower than a short cue because it remains present under conversation. If a sound is much louder than the others, lower that source or adjust a working copy in an editor; do not rely on a last-second volume change during a scene.
For OBS, the Audio Mixer Guide explains that its meters show audio levels and that the mixer includes source faders and mute controls. Watch the meter while auditioning your loudest cues, and listen through the actual output path. A meter alone cannot tell you whether the effect is comfortable or whether speech remains easy to hear.

6. Make controls easy to use under pressure
Group the sources or buttons in the order you expect to need them: ongoing beds first, then common transitions, then special cues. Use consistent labels and keep the few immediate controls visible. For example, label separate actions Start tavern bed, Stop bed, and Door cue rather than relying on ambiguous names such as Track 1. Keep a separate stop or mute control easy to reach so you can clear overlapping playback without hunting through menus.
Use a small number of distinct hotkeys if the application supports them. Avoid adjacent or easily mistyped key combinations, and do a dry run while speaking or reading a scene description. The useful test is whether you can find and trigger the intended sound without interrupting the session’s flow.
7. Run a full rehearsal and fix likely failures
Before the session, test from the same device, player, and output route you will use at the table. Start a bed, trigger a cue over it, stop each one, then restart the bed. Confirm the sound comes through the speakers or call that players will actually hear. In a virtual setup, test what participants receive rather than assuming local playback is also routed to the call.
Check for missing-file warnings, silent playback, unexpected looping, clipped peaks, and cues that start too late. If the player references files by location, leave the prepared folders in place after setup. Keep a simple backup plan—such as a regular player with the key ambience tracks—so the adventure can continue if the soundboard fails. The aim is a compact collection you can operate confidently, with sound supporting the scene rather than demanding attention.
