YouTube ambience for D&D games

You can run a game off a loop video, and sometimes you should. What one cannot do — a sound on cue, two distances — and how to rebuild the ones you reuse.

You can, and for a single quiet scene you probably should — a good ambience video is a good recording. What it cannot do is fire a sound on the beat you say, hold two distances at once, or come back next week in one tap. Rebuild the ones you keep reaching for as scenes, and keep the videos for the rest.

About 5 minutes · you need Thaumaturgy open, and a speaker or headphones.

1. Know when the video is the right answer

   It often is. If you want one long bed under a quiet session, or a particular piece of scored music, or you are setting up five minutes before people arrive and have never opened this app, a loop video is the shortest path and nobody should talk you out of it. The case for building the scene starts at the second or third time you reach for the same video.

2. Find the place rather than a search term

   A video search returns titles; the library is organized by where you are standing. Start from the place pages — cave, tavern, forest and the rest — each of which is a built-in environment taken apart dial by dial, so you can hear what it does and then change it. Press play on one and you are already level with the video.

3. Let the one-off sounds be one-off

   This is the difference that shows at the table. A video cannot open a door when somebody opens the door; it can only have a door in it somewhere, at a moment you did not choose. Put those on a board — big labeled buttons you tap as it happens — and the sound lands on your sentence instead of near it. See building a soundboard.

4. Put the far things far away

   A video is one finished mix: whatever the recordist decided is as close or as distant as it will ever be. Every layer here has a Distance dial that makes a sound quieter, duller and wider at once, so the crowd can be downstairs and the drip can be at your feet in the same room. Two distances is most of what makes a space feel larger than the table.

5. Save it as a scene, so next week is one tap

   Press + New scene and the environment and every board loaded with it come back together — the environment as a full copy, so it plays the way it did the night you saved it. Compare that with finding the video again, scrubbing past the intro, and remembering which of your tabs had it.

6. Learn the one key that stops everything

   Esc, or STOP ALL in the top bar, kills every sound at once — environment, loops, boards. A video tab needs finding first, and somebody will take a phone call. After the first visit the app has cached itself and the sounds it has played, so a dropped connection mid-session does not end the ambience either.

Can I just use a YouTube ambience video?

Yes, and plenty of good games run that way. The ambience channels are mostly careful recordings made by people who care about this, and for one scene with no setup they are hard to beat. Nothing below is an argument that you are doing it wrong — it is about the places you keep going back to, where a few minutes once buys you a tap every week after.

What can a loop video not do?

Not a question of quality. A video is a finished mix, and these are the things a finished mix cannot be:

Is the sound itself better?

No, and it would be a strange thing to claim. The difference is control, not fidelity. For the record, every recording in this library is public domain or was made for the app, and Sounds & licensing lists every one with its recordist — which is a different promise from quality, and the one we can actually keep.

What about music?

The built-in library is ambience and effects: the sound of a place, not a score. If you want a piece of music under the session, Your own sounds at the bottom of the Play screen takes any MP3, OGG, WAV or FLAC from your device — up to 250 MB — and a long file plays as a background track underneath everything else. So a video is not the only way to get a score under a scene, and if you would rather keep one running quietly in another tab for that, nothing here stops you.

Does it work without a connection?

After the first visit, yes — the app caches itself and the sounds it has played, which a streamed video by definition cannot. Worth knowing if you play somewhere with bad wifi, which is most places.

So should I stop using YouTube?

No. Keep it for what it is good at: a specific piece of music, a place you will visit once, and the evening you have had no time to prepare. Build scenes for the four or five places your table actually keeps returning to. That is the whole of the advice.
