Unison Sound Server

Unison – Distributed Audio Server & Zone Management Platform

Unison is a powerful, network-based audio solution designed for large-scale, multi-zone sound distribution. It provides a centralized audio server capable of managing unlimited audio zones, while leveraging distributed network peers that physically broadcast sound across a venue or site.

Built for flexibility, reliability, and real-time control, Unison is ideal for public spaces, smart buildings, events, museums, and immersive environments.

Core Features

Unlimited Audio Zones & Mixing
Create and manage unlimited audio zones, each with independent or shared mixes. Zones can be grouped into virtual zones for simplified control across complex installations.

Distributed Audio Broadcasting
Network peers deployed throughout the venue receive synchronized audio streams from the server and handle local playback, ensuring scalable and efficient sound distribution.

Hot Configuration
All system settings can be updated live, without service interruption. Zones, streams, volumes, and routing can be modified on the fly.

Wide Media Compatibility
Fully compatible with all FFmpeg-supported formats, allowing playback of virtually any audio codec or container.

Multiple Media Sources

• Local audio files

• HTTP-served media

• Real-time audio streams

Mix and route sources freely across zones.

MQTT Control Interface
Native MQTT integration enables seamless control from external systems such as automation platforms, IoT devices, show controllers, or custom applications.

Clock Synchronization
Accurate time synchronization across all network peers ensures phase-aligned playback and consistent audio timing throughout the installation.

Advanced Audio Processing

• Ducking for automatic volume reduction when priority audio is played

• Per-zone mixing and level control

Scalable Architecture
Designed to scale from a few speakers to large, distributed environments without architectural changes.

Typical Use Cases

• Smart buildings & campuses

• Museums & exhibitions

• Public announcement systems

• Retail & hospitality environments

• Immersive and interactive installations
