Add sound effects to your live stream, one key per sound

The right sound at the right second is half the joke — the airhorn on the clutch, the sad trombone on the death. Kloot keeps 85 of them in your control deck, so you search for the moment, pin the sound to a key, and press it mid-game. This guide walks the whole path, including the one OBS checkbox that decides whether your viewers hear any of it.

How do you add sound effects to a live stream?

Kloot puts 85 press-to-play sounds in your control deck. Pick one in the Media tool, pin it to a key, and it plays through your one overlay URL in OBS. Free fires 68 sounds with a short Kloot sting; Pro fires all 85 clean and adds repeats, counter sounds and Sound Flows.

What you’ll build

Built-in sounds on deck keys that play on stream through the Kloot browser source you already have.

Step by step

  1. 1

    Open Media → Sound library

    In your Kloot panel, open the Media tool. The Sound library sits below your own media — every built-in sound, nothing to upload.

  2. 2

    Find the sound for the moment

    Search by moment — “fail”, “win”, “reveal” — or tap a category. Trending shows what streamers press. Star the ones you use and they stay on top, with your last three right below.

  3. 3

    Try it

    The ▶ on a sound plays it on stream right away. To hear a key privately first, open it from your deck (⋯ → Edit) and press ▶ Preview — that plays here only, not on stream.

  4. 4

    Pin it to a key and set its volume

    Press 📌 to pin the sound to your deck. Then open the key (⋯ → Edit) and set its volume so it sits under your mic. Pro adds Repeat, ×2 to ×5 from one press.

  5. 5

    Make OBS play it

    Open the properties of your Kloot browser source in OBS and tick “Control audio via OBS”. It is the same single overlay URL you already use — nothing new to add. Without the tick, you hear the sound and your viewers do not.

  6. 6

    Fire it

    Press the key on your deck, or on your phone — the deck runs there too. On Pro, ⋯ → Copy webhook gives the key a URL, so a Stream Deck Website action or Streamer.bot can press it for you.

Sounds on your other keys (Pro)

Any key can carry sounds — an emoji rain, a lower third, a screen. Add up to 4 and they play when you press it, so one press is the effect and its sound together.

Sounds on keys and counters

Sounds on your counter (Pro)

A death counter can play a sound on every bump, on a count down, at a milestone, on a reset or when a streak climbs. Each moment gets its own sound from the library.

What a counter can play

Sound Flows (Pro)

Save up to 5 sounds as one key, played in sequence or layered on top of each other — up to 20 flows. Start from Winner reveal, Fail or Hype train and change them to fit your stream.

Your own sounds

Have a sound the library doesn't? Upload your own MP3, OGG or WAV to the Media tool and pin it the same way. Library sounds don't count toward your 2 Free media items (200 on Pro).

Common mistakes to avoid

  • ✕Leaving “Control audio via OBS” unticked on the Kloot browser source — the sound plays in your panel and never reaches the stream.
  • ✕Also capturing your desktop audio in OBS — your viewers hear every sound twice.
  • ✕Leaving a sound louder than your mic — turn the key’s volume down in ⋯ → Edit.
  • ✕Mashing one key — it waits until the sound has finished, so the second press does nothing.

Frequently asked

Are the sound effects free?

Yes, 68 of them. On stream, a Free sound ends with a short Kloot sting. Pro ($9/month) plays all 85 clean and adds repeats, sounds on other keys and counters, and Sound Flows.

Do they work on Twitch, YouTube and Kick?

Yes — anywhere your OBS scene goes. The sound plays through your Kloot browser source, so it reaches whatever platform you stream to.

Can a sound play by itself on a follow or a sub?

Kloot never fires anything on its own, and it does not read your chat or your alerts. On Pro, every key has a webhook URL (⋯ → Copy webhook), so a tool like Streamer.bot can press a sound key for you when something happens.

Can I upload my own sounds?

Yes. Upload an MP3, OGG or WAV to the Media tool and pin it like any other sound. Library sounds don't count toward your media items — Free holds 2 of your own, Pro 200.
