The Immersive Audio Revolution

SPAT Revolution, the most comprehensive real-time 3D-audio mixing engine ever designed, provide artists, sound-designers and sound-engineers the possibility to control the position of audio-sources in a three-dimensional environment, add room effects, send the result to a loudspeaker setup or a pair of normal stereophonic headphones, or export the result as audio stems to use in any other audio engine.

With a solid modular object based concept, the ability to specify and automate the spatialization parameters independently of the output format, support for different types of hardware and software inputs/outputs with network support for audio and automation (using Open Sound Control), innovative 3D-audio signal visualization modes and precise signal level control, it provides a flexible, efficient and creatively inspiring working environment designed to preserve emphasis on simplicity and ergonomics.

Workflow Integration

Created for audio professionals, within the fields of audio mixing, post-production, sound design, VR-engine audio, computer game audio, live and installation sound, SPAT Revolution is designed to easily integrate with various workflows using standard hardware audio interfaces, network audio, and a software audio gateway plug-in to communicate with all major DAWs (AAX, AU, VST).

  • Composition
  • Film and Music
  • Post-production
  • Computer Games
  • Virtual Reality
  • Sound Design
  • Research & Development

Unlimited number of Inputs and Outputs

SPAT Revolution supports unlimited number of audio inputs and outputs, with the only actual limitation dependent on computer workstation and audio hardware specifications.

DAW integration is supported using standard plug-ins (AAX, AU, VST) (Experimental) for audio input and output streaming between the DAW and SPAT Revolution through local path or over network.

Unlimited number of Sources

The audio inputs are connected to an unlimited number of source objects providing an extensive set of parameters controlling all aspects of the source in the space including; position, barycentric, radiation as well as perceptual factors such as presence, warmth, brilliance.

Multiple Input Stream Formats

SPAT Revolution mixes, reverberates and spatializes audio from all types of microphones, arrays, high order Ambisonic captures, and from any type of pre-produced stems, supporting a vast range of input stream formats.

  • Channel-Based (C.B) ; any number of inputs
  • Higher-Order Ambisonic (HOA) ; up to order 7
  • A-Format
  • B-Format

  • Mid-Side (MS)
  • Binaural
  • Transaural

Multiple Input and Output Transcoders

A wide range of input and output transcoders are provided, including:

  • Channel Based (C.B) to Channel Based; Channel splitter aggregator

Unlimited number of Spatialization buses

Multiple 3D-spatialization technologies can be combined and mixes in different formats rendered simultaneously.

  • Stereo (AB, XY, MS)
  • Binaural rendering for headphones (with compensation for nearfield effects)
  • Transaural rendering for loudspeakers
  • Vector-based amplitude panning (VBAP 2D & 3D)
  • Distance-based amplitude panning (DBAP 2D & 3D)
  • Vector-based intensity panning (VBIP 2D & 3D)
  • Nearest-neighbor amplitude panning
  • Speaker-placement correction amplitude panning (SPCAP)
  • Ambisonic equivalent panning (AEP)
  • B-format and Higher Order Ambisonic (HOA), Encoding/Decoding up to 7th order, Integrating different decoding methods (Projection, Pseudo-Inverse, Energy-Preserving, AllRAD)

Comprehensive Loudspeaker Configuration

The unlimited number of outputs are configurable in any kind of current speaker system setup format, as well as with custom speaker system setups.

  • Stereo
  • QUAD
  • 5.1
  • 7.1
  • CUBE
  • Dolby Atmos
  • Auro 3D
  • Mpeg H
  • Demi Sphere
  • NHK 22.2
  • Various other formats

Full Control with plug-ins and OSC

Control and Automation of Sources, Rooms and Masters from all major DAWs is provided using plug-ins (AAX, AU, VST) (Experimental), and control from other devices such as digital mixing desks and other controllers is supported using Open Sound Control (OSC).

Important Note about Audio Input/Output with Plugins

The audio input and output streaming between SPAT and DAWs or any other Host software using plug-ins, is provided even though it’s still in an Experimental stage.

The audio streaming using the plug-ins will work fine in certain configurations, but are not guaranteed to work in all setups and configurations.

The development is continuing and all updates of its progress will be posted here on this webpage.

SPAT Revolution Partnership

Spat Revolution is the result of a successful partnership between Flux:: and the French research institute IRCAM (Institut de Recherche et Coordination Acoustique/Musique), created to make decades of groundbreaking research performed at IRCAM available to the world in a format adapted for the workflow in the digital music and audio industry!

SPAT Revolution - A living organism

With the diversity of the SPAT Revolution, so many different scopes for using it, and with so many users already expressing their different needs and requesting features, it has already become like a living organism.

The decision to release the software, does not mean that this is it, this is what you get and that’s it. Au contraire, we already have a long list of features and updates in development, and the team working on the software will stay busy for an unforeseeable future moving the SPAT Revolution project forward.

Send

The SPAT Revolution Send plugin is used for sending DAW automation data to the SPAT Revolution through local path or a network.

With the Send plugin audio can also be sent from the DAW to SPAT Revolution (Experimental)

Return

The SPAT Revolution Return plugin is used for sending automation data from SPAT Revolution to a DAW through local path or a network.

With the Return plugin audio can also be sent from the SPAT Revolution to a DAW (Experimental)

Room

The SPAT Revolution Room plugin is used for sending automation data for controlling the Rooms in SPAT Revolution through local path or a network.
