Sonical

A universe of apps for your ears

The smartphone put a computer in your pocket. We’ve built one for your ears.

Sonical builds CosmOS, the operating system for the ears.

The problem

Every audio device ships frozen in time.

When you buy a new audio device, that’s all it will ever do. The hardware could do more. The software is locked.

The solution

CosmOS turns any audio device into a computer for your ears.

One operating system for everything your device can hear and sense. Install apps, chain them together, and change what your device does years after you bought it. We call them personal hearing computers.

How it works

Apps, but for your ears.

We have apps for our phones. Why should they stop there? Developers publish audio apps to the cloud. They download through the phone you already own, onto the CosmOS device in your ears. No new phone, nothing extra in between.

 

How CosmOS works in detail →

The platform

One OS. Every audio device.

CosmOS runs on the device itself - audio, sensors and every data stream the hardware carries. Real-time scheduling, multiple apps processing the same stream, and latency low enough for professional monitoring.

And more on the way. You choose the apps your device runs, so it fixes what matters to you, not just what every product ships with. See what CosmOS can do →

CosmOS, running.

A short film of CosmOS running on Remora is in production.

The ecosystem

Four players. One ecosystem.

Sonical is the technology company at the center: we license the OS, the apps platform and the reference designs. Our partners build the products.

Each new app makes every device worth more. Each new device gives developers a bigger audience.

Who it helps

Made for how people actually hear.

Illustrative examples
The mix engineer

monitors a live session with latency under 5 ms over UWB, while a hearing protection app tracks exposure in the background.

The listener with hearing loss

runs a correction app tuned to their hearing, with dialogue enhancement for TV, on the same device everyone else buys.

The gamer

runs spatial audio for positioning and a clarity boost for voice chat, tuned per game.

The immersive listener

runs spatial audio and crossfeed for films, games and concerts, and swaps the mix as easily as phone apps.

Every experience, elevated and personalized.

Momentum

Already underway.
