Soundboard
A soundboard lets viewers pay to play a sound on your stream. You build a board of clips, each with its own price, and viewers tap one from your portal to play it live through your overlay. You keep 80% of what they spend.
The 60-second setup
- Open the board. Go to Soundboard.
- Add sounds. Grab the built-in starter pack in one tap, or upload your own clips. Give each a name and a price in coins.
- Add your overlay to OBS. Sounds play through your Landmark overlay browser source. Any Landmark overlay works, and no extra element is needed.
- Go live. While you are live with the overlay open, the soundboard shows on your portal and viewers can play the sounds.
Adding sounds
- Starter pack
- Eight built-in effects: airhorn, drumroll, sad trombone, boing, ding, buzzer, applause, and record scratch. Add all of them, or pick the ones you want. They are free to add.
- Your own clips
- Upload MP3, WAV, OGG, or M4A files up to 8 MB each. Name it what viewers should see. A board holds up to 60 sounds.
Preview any sound with the play button on the dashboard. That plays it in your browser only, never on stream, so you can hear a clip before viewers can.
Pricing
Each sound has its own price in Landmark Coins, from 5 coins up. Viewers pay from their Landmark wallet, the coins move to yours, and Landmark keeps a 20% commission on the sale. That is the same commission as every other redeem, so a 25-coin sound nets you 20 coins.
How it plays
When a viewer plays a sound, it fires instantly through the audio sink built into every Landmark overlay. There is nothing to place and no rule to write. You can set each sound's volume on the board, and the global alert-sound mute in the Control Dock silences the soundboard along with your alerts.
When it is available
The soundboard shows on your portal only while you are live and your overlay is open, so a viewer is never charged for a sound that has nowhere to play. If the overlay closes, the sounds drop off the portal until it comes back.
Turning a sound off
Toggle any sound to Off to hide it from your portal without deleting it. Delete removes it for good. Both take effect on open portals right away.
