Leson by Music Unit unveils DeepStereo

Music Unit and its spin-off Leson unveil DeepStereo, a new immersive sound technology aiming to immerse listeners into a soundscape, regardless of their equipment. DeepStereo combines an innovative format and a tool to transform any mono or stereo file into a 3D immersive audio experience.

Compatible with all headphones, speakers, and soundbars, this patented system performs real-time transformations without the need for complex installations or reliance on proprietary ecosystems. Algorithms developed by Music Unit ensure 3D transformations that retain the richness and dynamics of the original sound without the artifacts found in other formats.

“This technology offers artists and producers an unprecedented way to create 3D soundscapes”, says Julien Chirol, co-founder of Music Unit and Leson. “For instance, artists can precisely position instruments and effects within a three-dimensional space, adding depth and detail to their compositions. This enables listeners to feel uniquely connected to the music, as though they are enveloped by sound. Most importantly, DeepStereo truly democratizes immersive audio: it transforms any device into a 3D experience, anywhere and for everyone.”

For electronic device manufacturers, DeepStereo offers a software or hardware solution for products like smartphones, headphones, and connected speakers. For streaming platforms, it enhances the music and movie listening experience. For studios and content creators, DeepStereo simplifies immersive audio production. Artists can transform their work into 3D immersive experiences from standard stereo files. DeepStereo also transforms live sound engineering - by incorporating spatial audio into concerts, sound engineers are able to create 3D environments.

The creation of content in DeepStereo relies on Music Unit’s patented My Bee Knows binaural technology, which aims to preserve the original signal quality, making it compatible with any playback device, whether headphones or speakers. Binaural synthesis mimics natural hearing, where each ear perceives sound with slight temporal and tonal differences.

The artificial reproduction of these “transfer functions” tricks the brain into perceiving the virtual spatialization of a sound that originally lacked it. Combined with a process that includes crosstalk cancellation, Deep Stereo delivers a sound immersion on regular speakers. The rendering becomes compatible with Deep Stereo’s specifications for any format, whether mono, stereo, 5.1, or multichannel.

DeepStereo is the result of twelve years of collaboration between Leson and French institutions including the CNRS, École Polytechnique, and the Paris Conservatory. The solution is already adopted by the Cité de la Musique for audiovisual content production and distribution. It is also integrated into Nous Digital’s Sonic HR 6DoF headphones used in museums and is currently under trial at Radio France.
