About Us Hero


Sounds and stories

Lead by Cyril Holtz (re-recording mixer) and Antoine Martin (sound editor / developer), HAL is a small brand whose philosophy is to meet the needs of sound people working in post-production, with innovative, efficient and great sounding tools.

HAL has designed a number of audio plug-ins and software packages already in use in post-production studios around the world.

Under the impetus of audio-naturalists Mélia Roger (sound engineer) and Grégoire Chauvot (sound editor), HAL has also specialized in the creation of immersive sound banks created with its exclusive 7.0.2 spaced array: the Atmos Tree.

HAL is part of the Poly Son Post Production group, a post-production services company based in Paris and Lyon (France). Poly Son offers all image and sound post-production services: dailies management, digital lab, editing, color grading, sound editing, mixing, sound effects and mastering. Poly Son has also won 2 César & Techniques awards, in 2015 and 2019.

Poly Son's creative associates are from every link of the production and post-production chain, including cinematographers, editors, sound engineers, sound editors and mixers, who have worked on hundreds of films, series and podcasts - and have won over fifteen César, and even the Oscar for Best Sound for the film Sound of Metal.
