The most wanted Panning methods and Spatialization techniques at your fingertips
Render for various deliverables
Audio is literally living a paradigm shift, moving beyond stereo to various spatial audio techniques. At the core of SPAT Revolution is a desire not to impose on panning methods and spatialization techniques rather to offer a wide range of possibilities, including panning techniques for working with audiences in wide areas not confined to traditional sweet spots for live and installation setups.
Being for improving the frontal resolution for concert diffusion, to immerse the audience with surround audio, to render to any channel-based or scene-based formats, to deliver spatial audio over headphones, SPAT Revolution simply opens up to the most advanced techniques and brings them to your fingertips.
Deliver a stable soundscape throughout an entire listening area with WFS
With today’s demand for the entertainment to completely immerse the audience in the experience, and for producing a stable soundscape image throughout an entire audience listening area, the distinctive WFS , Wave Field Synthesis technique for spatial audio reproduction is offered as a license add-on option to SPAT Revolution Ultimate offer.
WFS aims to reproduce the true physical attributes of a given sound field (the waves front) over an extended listening area, an approach that relies on delay and amplitude. It is deployed on collinear speaker systems (line of speakers in a frontal setting) and with qualified 2D/3D speaker arrangements surrounding the audience.

Encoding and Decoding with Transcoding Modules
SPAT Revolution objects stream type can span from many types of microphones, arrays, HOA captures, and from any type of pre-produced stems. It can render content in HOA up to 7th order. Supporting a vast range of stream formats, transcoder modules allow modification of 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.

Multi-Virtual Room (Ultimate Only)
In SPAT Revolution the source objects are spatialized inside virtual rooms with spatial positioning, panning, reverberation and output format taken into consideration when calculating the output rendering.
In order to encompass various different workflows or render different deliverables, multiple rooms can be created and used simultaneously, in parallel, with individual independent output formats.
Summing this up is the ability to binaurally monitor (virtualize) a scene from a channel based output, giving an impression of how the mix might sound diffused by a particular speaker arrangement (including the space between speakers and gain characteristics belonging to selected panning types).
Unique Nebula Spatial Spectrogram (Ultimate Only)
Nebula is a technology adapted from FLUX:: Analyzer System, simulating how sound sources localize their sound over different speaker setups, providing a unique representation of the sound-field, in terms of spectral content and localization, in real-time inside the 3D virtual room display.
