Every device,
one system.

MUSIXQUARE turns multiple phones, tablets, and laptops into one sound system. No installation. Just share one code.


Surround, without
surround speakers.

Each device plays one role: left, right, subwoofer, or full stereo. The room itself becomes the system.

No speakers on
your computer?

MUSIXQUARE works as a quick stand-in. A phone and a tablet from your bag are enough to start.

Feature
System Audio Sharing (Beta)
Platform
Chromium-based browsers on computers

Beta: desktop Chromium only, up to four connected devices including the publisher. Remote shares and all Cloudflare-relayed (SFU) shares end after two hours; a verified PRO LAN-direct share may continue while room authority remains healthy. Live audio has unavoidable latency, so the sharing device should lower its volume.
