Professional multizone audio platform

Every source.
Every zone.
Under control.

TerraceDSP turns a computer and audio interface into a professional multizone system. Route applications, live inputs and announcements—then shape the sound with presets built for people who need results, not an engineering degree.

Built for real spaces

Professional audio should not require a professional at every control.

TerraceDSP makes a powerful signal path understandable enough for daily operation while keeping the precision needed for commissioning and live production.

Hospitality

Cafés, hotels and spas

Keep every space at the right level, switch the atmosphere instantly and make announcements without disturbing the whole venue.

Education

Schools and media centres

Route lessons, presentations, microphones and playback exactly where they are needed—from one clear control surface.

Events

Concerts, theatre and DJ sets

Bring professional routing and processing to a one-off production without buying a permanent licence or building a complex control rig.

Installations

Any multizone venue

Run independent sources in lounges, terraces, studios, halls or outdoor areas while keeping one verified DSP path.

The TerraceDSP workflow

Simple to run. Deep when you need it.

Daily operation, system tuning and repeatable setups live in the same application.

01 · Operate the whole system

One view for the room you are in.

See levels, outputs and system state without digging through engineering menus. The daily controls stay direct and readable.

02 · Shape and protect the sound

The depth professionals expect.

Shape every output with precise EQ, then let Dynamic Protect preserve as much boost as the available headroom allows. Live gain-reduction feedback shows exactly when the system is protecting the signal.

03 · Repeatable by design

Great sound should be easy to recall.

Presets capture the processing that makes a system sound right. Scenes restore how sources, zones and levels should operate for each moment.

04 · Our own Windows audio driver

Every application gets a clear, independent path.

TerraceDSP includes its own multichannel virtual audio driver. Assign an application to one of four clearly named stereo inputs in the Windows mixer, then route and process it independently inside TerraceDSP.

How it works and what it can do

One visible path from every source to every space.

TerraceDSP turns the audio path into five understandable steps. Choose what plays, where it goes, how it sounds and how the system protects the loudspeakers.

Sources

Apps · microphones · players · announcements

Route

Send any source to one room, several zones or all outputs

Shape

EQ · dynamic headroom protection · crossover · delay

Protect

Output gain · limiter · soft clip · emergency mute

Zones

Independent rooms, loudspeakers and multichannel outputs

For daily operation: select a scene, adjust a zone or make an announcement. The complex processing stays out of the way.

For system tuning: open the full DSP controls and commission every output with precise routing, filtering, timing, dynamics and protection.

Features

A complete multizone audio system—not another volume control.

Every function belongs to the same saved and supervised signal path, from application capture to the physical outputs.
