Hi Product Hunt! 👋
I’m the solo developer behind CartLayer.
I built it because I wanted a simple, reliable soundboard for live broadcasting on macOS.
CartLayer is designed for live shows. You can trigger jingles, ads and sound effects instantly, control your microphone with a single pad, and stream your show directly to an Icecast server. It’s a great fit for internet and FM radio stations, live events, podcasts and anyone who needs instant audio playback.
I’d love to hear your thoughts:
* What features would you expect from a professional live soundboard?
* Are there any workflows you’re currently missing in your setup?
I’ll be here throughout the day to answer questions and collect feedback. Thanks for checking out CartLayer!

How does it handle triggering sounds during a live show if the network drops out for a second, and is the mic input routed through the app or straight to the streaming server?

@kasmova72003 Sound triggering is completely local. All playback and cart triggering happen inside the app, so a brief network outage won’t affect your live show or playback timing. If the connection drops, only the outgoing stream is interrupted while the show continues running locally.
The microphone is also routed through the app, where it can use processing such as compression and automatic ducking before being mixed with the rest of the audio and encoded for the streaming server. It isn’t connected directly to the streaming server.

The microphone toggle in one click is exactly the kind of detail that shows you understand live radio workflow. Nice execution on a genuinely purpose-built tool.
