Mixing, Routing, Processing, Recording

FusionDesk

A Windows software mixer for flexible audio routing, sandboxed VST3 processing, direct recording, and monitor control across ASIO, Windows Audio, and Per-Application Audio Capture.

v0.6.133.3524 Beta-2

Routing Without Hardware Lock-In

Inspired by the matrix-mixer workflow of RME TotalMix FX.

Build independent mixes from the same sources, send them to different destinations, and keep the whole session visible in one dense, console-style interface.

FusionDesk brings that always-visible routing philosophy to the wider Windows audio world: professional ASIO interfaces, standard Windows devices, application audio, VST3 insert chains, snapshots, monitoring, and recording.

Core Features

Everything visible. Everything routable.

32 x 32 Mix Matrix

Create up to 32 independent stereo mixes from the same sources. Each output can have its own blend while strip controls stay predictable.

ASIO, WASAPI, and PAC

Use professional ASIO channels, standard Windows Audio devices, virtual audio devices, and Per-Application Audio Capture in one session.

Sandboxed VST3 Hosting

Third-party plugins are isolated from the mixer. If a plugin crashes or hangs, FusionDesk keeps audio running and lets you reload the slot.

Built-In Recording

Record inputs and outputs to WAV, FLAC, or MP3. Loop capture keeps a rolling buffer so you can export the last moments after they happen.

Control Room Monitoring

PFL, AFL, Solo, listen output routing, monitor processing, LUFS metering, peak holds, and live status readouts sit where you need them.

Native Dynamics

Load the built-in Compressor and Limiter like insert plugins, with strip-style metering and gain-reduction displays on the channel strip.

The Mixer

Designed for people who need to see the whole signal flow.

Input strips, output strips, mix buttons, plugin slots, meters, recording controls, and the Control Room stay on one screen so routing decisions remain visible. Keep your favourite audio sources together, then send them to speakers, headphones, recorders, streams, or call apps as needed.

Use Cases

Built for practical Windows audio rigs.

Audiophile Listening Rooms

Route music to multiple speaker pairs and headphone chains, keep favourite sources in one place, and use separate EQ or correction for each listening output.

Multichannel Listening Rigs

Use FusionDesk as a flexible routing layer for custom speaker layouts, multichannel DACs, and room-correction paths.

Studios and Musicians

Build headphone mixes, route DAWs and media players, insert room correction or headphone EQ, and save complete setups as snapshots.

Livestreams and Content Creation

Capture microphones, browsers, games, music players, guests, and comms apps separately, then decide exactly what each destination hears.

Live and AV Work

Create monitor sends, recording feeds, utility mixes, and backup routing from one screen, with live-performance protections for show use.

Voice and Video Calls

Send selected audio sources into a messaging or conferencing app during a call while keeping your own monitor mix separate.

Real Session Tools

The everyday details matter.

FusionDesk keeps setup, routing, plugin choice, and recording checks close to the mixer so you can make changes without losing the session.

Per-Application Audio Capture

Capture browsers, media players, DAWs, messaging apps, and other sources, then route them like any other input.

Plugin Management

Load native dynamics or third-party VST3 plugins, organise favourites, hide plugins you do not use, and keep insert chains ready.

Recording Confidence

Check disk usage, recording rate, remaining time, and estimated full date before committing to a long take.

Audio Quality

Transparent by design.

FusionDesk runs a 32-bit floating-point mix bus with constant-power pan law, calibrated RMS and LUFS metering, and adaptive resampling for asynchronous Windows audio sources.
