"Horizo isn't segmented by instrument.
It's unified by devotion."

— The Horizo principle

Three environments

Every record has a mood. Now you can match it.

Studio

Surgical precision

Isolate stems, adjust levels, hear the session as the engineer did. Every instrument on its own track.

Open

Spatial immersion

The record expands around you. Instruments breathe and separate across a wide, open soundstage.

Nightsky

Late night listening

Low light, deep focus. The music slows and settles. For the hours when you just want to disappear into it.

What Horizo does

Built for the obsessive listener.

01

Real-time stem separation

Upload any track. Horizo separates vocals, bass, drums, and instruments in seconds — powered by the same technology studios use.

02

Time-stretch without pitch shift

Slow down a solo to learn it. Speed up a section to study it. The pitch stays true — only the tempo moves.

03

Works on any device

No download. No install. Horizo runs in your browser as a progressive web app — on your phone, tablet, or desktop.

04

Built for devotion

For the person who listens to the same record fifty times. For the musician who needs to hear what the bassist actually played. For the obsessive.

Hear what you've been missing.
