EMPOWER CREATIVITY
The Immersive Audio Revolution
From Creation to Real-time Immersive Delivery
Empowering artists, sound-designers and sound-engineers virtually unlimited possibilities to design, create and mix an outstanding real-time immersive experience.
From decades of groundbreaking research at IRCAM
Spat Revolution is the result of a successful partnership between Flux:: engineering and the French research institute IRCAM (Institute for Research and Coordination in Acoustics/Music), 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.

Spatialization, Sources and Room Simulation
The incoming audio signal is assigned to a practically unrestricted number of source objects, with the only actual limitation set by the computer hardware specifications. Each source object is attributed with 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.
The source objects appears in a virtual room, and may also be assigned to multiple virtual rooms, with different acoustic simulations and multiple different output destinations.
Designed to integrate into any workflow

Creative and Comprehensive Real-Time Spatialization
Virtual Room Concept
In Spat Revolution the source objects are spatialized inside virtual rooms with internal spatial positioning, panning, reverberation and output format taken into consideration when calculating movement and position inside the room. The idea is that by simulating speaker positions and acoustic interactions, the process of mixing for a particular speaker layout becomes more predictable.
For example, by monitoring binaurally a scene from a channel based room, it is possible to get an impression as to how the mix might sound diffused by a particular speaker arrangement (including the space between speakers and gain characteristics belonging to selected panning types).
In order to encompass various different workflow ideas or experimental approaches, several different rooms can be created and used simultaneously in parallel, with individual independent formats including; Channel Based, Binaural, High Order Ambisonic (HOA), B-Format and Mid Side.
Multiple Input and Output Transcoders
SPAT Revolution mixes, reverberates, and spatializes audio from many types of microphones, arrays, HOA captures, and from any type of pre-produced stems.
Supporting a vast range of input stream formats, Transcoder modules may modify the channel count of the stream passing through it, depending on the format transfer being requested.
For example, transcoding from Ambisonic B-Format into a Channel Based 3D Cube involves a four-channel Ambisonic stream getting transcoded into an eight-channel stream grouped and treated as a specific speaker configuration.
Transcoders Supported:
- Channel Based (C.B) to Channel Based; Channel splitter aggregator
- HOA to HOA for conversion of normalization and channel-arrangement
- HOA to Channel Based
- A-Format to B-Format
- A/B-Format to Channel Based
- A/B-Format to HOA
- B-Format to UHJ
- UHJ to B-Format
- Mid/Side (MS) to Channel Based
- Binaural to Transaural
