SPAT Revolution – The Ultimate Immersive 3D Audio Software Tool

Flux:: Sound & Picture Development, creating intuitive and technically innovative audio software tools in partnership with IRCAM, one of the world’s leading public research institutes within the fields of musical expression, sound, and acoustics, are today pleased to announce the release of SPAT Revolution.

The Audio industry is undergoing a profound evolution and Flux:: Spat Revolution is here to tackle it. Total immersion is the future of the gaming and entertainment industries. Augmented reality is no longer an abstract notion, it is now dramatically affecting how we work, play, educate, and communicate, as data is being converted to construct a totally 3D immersive environment.

SPAT Revolution is the long awaited answer for sound-designers and sound-engineers that need a solid real-time 3D-audio mixing engine that offers the possibility to control the position of any audio-sources in a three-dimensional environment.

SPAT Revolution mixes, reverberates and spatializes audio from any types of microphones, arrays, high order Ambisonic captures, and from any type of pre-produced stems. The Spat Revolution can handle any number of channels from Stereo, QUAD, 5.1, 7.1, Atmos, Auro 3D, etc. Multiple 3D-spatialisation technologies (VBAP, DBAP, HOA, Binaural, etc.) can be combined, mixed and rendered in different formats simultaneously. It can even export the result as “audio stems” to be used in any other 3rd party audio engine.

Spat Revolution’s intuitive modular object based concept offers the ability to specify and automate the spatialization parameters independently from the output format. “Open Sound Control” supports different types of hardware and software inputs/outputs with full network support for audio and automation. The Innovative 3D-audio signal visualisation modes and precise signal level controls provide a simple, ergonomic and inspiring working environment.

Created for audio professionals, working in 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 different workflows using standard hardware audio interfaces, networked audio, and a software audio gateway plug-in to communicate with all major DAWs with full AAX, AU and VST audio plug-ins support.

SPAT Revolution is a ground-breaking software that has been designed to deliver the highest 3D audio mixing quality and satisfy the growing industry’s “immersive audio” sonic demands.
