Trinnov Audio is a French audio technology company founded in 2003 by Arnaud Laborie, Rémy Bruno, and Sébastien Montoya, who first met at IRCAM, the Paris-based institute for musical and acoustic research. The company designs and manufactures digital signal processors for professional studio monitoring, immersive sound, home theater, and cinema, with all products engineered and built in France.

Trinnov is best known for its Optimizer technology, a digital room and loudspeaker correction system first introduced to audio engineers at the AES convention in 2005. The Optimizer underpins the company's professional monitoring processors such as the ST2 Pro and the NOVA, and the platform has been adopted in mastering, broadcast, and post-production facilities. For cinema, Trinnov developed the Ovation processor, while the Altitude line — including the Altitude32 (36 channels) and the Altitude16 (20 channels) — has become a reference for immersive-sound playback in high-end home theaters since its 2014 introduction.

The company's processors combine high channel counts, loudspeaker and room calibration, and support for object-based formats like Dolby Atmos, DTS:X, and Auro-3D. Trinnov's products are sold through specialist pro-audio and high-end installation channels rather than mass-market retail, and the brand has built a niche reputation among mixing and mastering engineers, acousticians, and custom-install integrators.

Trinnov has 12 products cataloged on Equipboard, including Studio Monitor Management, Condenser Microphones, and Effects Processors. Their gear is featured by 2 artists, with the strongest followings in Electronic, Hip Hop, and Orchestra. Notable users include Tommee Profitt and Mark Knight.
