Free Slack Soundboard for Huddles

Play a drum roll, applause or your team's in-joke into a Slack huddle you join from Chrome. Free, no sign-up.

Your browser will ask for microphone access when you click.

Set it up in Slack

Send your sounds to the extension
Open the Facecam soundboard, keep the starter sounds or add your own clips (up to 30 seconds each), and click Use these sounds in calls.
Open Slack in Chrome
Go to app.slack.com in Chrome rather than the Slack app, and start or join a huddle in a channel or DM. Allow the microphone when Chrome asks.
Switch the huddle mic
In the huddle, click the three dots or gear icon and open Manage video and microphone settings. Choose “Facecam Virtual Mic” as the microphone.
Play a sound
Open the Facecam popup → More → Soundboard and press a pad, or use the shortcut keys you set at chrome://extensions/shortcuts.

Problem	Fix
The microphone list has no Facecam mic	You're in the Slack desktop app, or the tab loaded before the extension. Open app.slack.com in Chrome and reload.
Nobody hears the clips	The huddle is still on your real microphone. Change it in Manage video and microphone settings.
Clips sound clipped or quiet	Calls favour speech and can treat long music as noise. Use short, punchy clips and test with a teammate first.

	Slack in Chrome	Slack desktop app
Huddles	Yes (Slack lists Chrome on Mac, Windows and Linux)	Yes
Facecam soundboard	Yes, through Facecam Virtual Mic	No
Video in huddles	Camera icon at the bottom of the huddle	Same

Slack's huddle help doesn't describe one. Playing clips through your microphone is what Facecam adds in Chrome.

Yes, with no account. The soundboard runs on your computer.

No. They hear the clips in whatever Slack app they use, because the clips arrive as your microphone.

Yes. The voice changer uses the same Facecam Virtual Mic, so you can do both at once.
