FLUX:: Immersive

What FLUX:: Immersive does

FLUX:: Immersive (formerly FLUX Software Engineering) is a French professional audio software company founded in 2006 by sound engineer Gaël Martinet and headquartered in Meung-sur-Loire, France. The company develops a portfolio of professional audio software centered on three product lines: SPAT Revolution, a real-time immersive audio mixing engine supporting Wave Field Synthesis (WFS), Ambisonics, binaural, and traditional speaker formats with object-oriented and perceptual mixing; MiRA, an audio analysis suite for real-time calibration, visualization, and system tuning; and a suite of dynamics, EQ, spectral, and reverberation processing plugins including products commercialized under long-standing partnership with IRCAM (IRCAM Trax, Verb, Hear). SPAT Revolution is described as the direct commercial output of FLUX::'s research collaboration with IRCAM, one of the world's leading public acoustics and music research institutes.

The business operates a multi-tier commercial model combining perpetual licenses ($79-$1,995), monthly subscriptions ($7.95-$79.95), a Rent-to-Own program (24 monthly payments converting to a perpetual license), bundles (Ultimate Pack, Immersive Essentials, Studio Session Pack), and education-specific licensing. Distribution occurs via the FLUX:: online store and FLUX:: Center platform, supplemented by certified integrators (e.g., Espace Concept in France) and, following the December 2023 acquisition by HARMAN Professional Solutions (a wholly-owned subsidiary of Samsung Electronics), HARMAN's global enterprise distribution network spanning 165+ countries. Customer segments span music creation studios, live production, post production, mastering, installation sound, and education, with named customers including Skywalker Sound, DreamWorks Animation, NBCUniversal, NHK, Cirque du Soleil, Disney Parks, Sterling Sound, Remote Control Productions, Biwako Hall, and Culturgest Lisbon.

The company is privately held as a brand/product line within HARMAN Professional Solutions following the December 2023 acquisition, retains operational identity and headquarters in Meung-sur-Loire, and continues to release major product updates annually (SPAT Revolution 22.02, 23.08, 24.06, 24.08, 25.01, 25.12, 26.04; MiRA 25.04, 25.07, 26.04).
