Welcome to SPAT Revolution

Product Page | Shop Page

First of all, thank you for acquiring SPAT Revolution. We hope it will provide you with new levels of productivity, creativity and experience in sound design. Our goal was to deliver the most comprehensive real-time spatial audio renderer ever designed, and to make the whole process of spatialized audio production powerful and intuitive for beginners and professionals alike. Our real-time audio environment provides easy access to some of the most advanced spatialisation algorithms currently available, at the very best sound quality currently possible.

‘SPAT’ is short for Spatialisateur in French. It is a real-time audio library that allows composers, sound artists, performers and sound engineers to control the localisation of sound sources in virtual and real 3D auditory spaces.

SPAT Revolution wraps the ‘Spat’ processing library in a luxurious and characteristic graphic environment to help visualise many aspects of a spatial audio composition in realtime. This graphic interface allows sound mixes to be composed as interactive spatial models existing in Virtual Room. SPAT contains a powerful multichannel reverberation engine which can be applied to design and add a sense of auditory space in studio mixes and realtime on location.

Different needs, different tools

SPAT Revolution comes in different flavors: an Essential and an Ultimate version. Both share the same audio engine and powerful 3D audio capabilities.

The Ultimate license brings the complete set of tool needed for professional already working for immersive audio creation content. It delivers the full flexibility, powerful routing and complex option sets of SPAT Revolution.

The Essential license supports the more common workflow scenarios in a more accessible manner. While it has the same audio capabilities, the intent is for a simpler user experience, with fewer options and a more straight forward approach to immersive audio creation.

Ultimate and Essential : what’s common?

The SPAT Revolution software supports with the same installer (binary) both license options and has the common features listed below:

Ultimate and Essential: Differences

SPAT Essential comes with a set of limitations:

Complete specification is available here

Ultimate vs Essential sessions

Both Essential and Ultimate are based on the same session. In order to allow for sessions created with Ultimate license to be compatible (or simply opened) with Essential, a simple compatibility dialog tool welcomes you at session opening, offering for a partial read based on the limitations set by the Essential license. Speaker arrangements of any size can still be managed (created, imported, exported) but only valid ones for Essential can be applied to the session.

SPAT Revolution’s Heritage

SPAT Revolution is underpinned by 30 years of technical research and development in acoustics and sound.

Behind SPAT Revolution is the partnership of FLUX:: SE and Ircam in Paris, France. Founded in 1977, Ircam is one of the world’s leading public research institutes in the fields of musical expression, science of music, sound and acoustics. The first result of this partnership was the plugin suite IRCAM Tools. In that release was the first incarnation of SPAT as a DAW plugin based on over 30 years of research with Ircam’s Acoustic and Cognitive Spaces Team. After decades of development the next step was the full production environment for spatial audio - SPAT Revolution through the elegant simplicity of the graphic interface, SPAT Revolution represents a formidable achievement. It brings together the technical expertise from decades of academic research and development at IRCAM into an easy-to-use package that is flexible and powerful enough to meet all the demands of spatial audio production, from day to day surround sound post-production to the most challenging realtime installations. As you will discover, SPAT Revolution can handle a virtually unlimited number of input and output audio streams and is prepared for all formats and 3D-audio workflows currently available or imaginable in the audio industry.

Although this user guide cannot cover every technical aspect of the algorithms and expert knowledge contained within SPAT Revolution we hope you will feel assured that the science behind the sound is absolutely correct.
