  • Transparent to the user as no specific configuration is required
MBK is preferred over competing solutions in 80% of cases!
Developed over twelve years in partnership with the CNSMDP, the École Polytechnique and the CNRS, MBK is a software that transcribes all types of 3D audio files into a universal format that can be read by any device. It uses a unique patented signal processing method to implement a binaural synthesis system that does not alter the timbre of the sound sources. This precision places it at the forefront of 3D audio rendering engines available on the market.
With an optional head tracker, it offers a fully immersive and interactive sound virtual reality experience. It is particularly efficient in terms of required computing power and can be easily integrated into all types of hardware and software environments.

Based on patented audio technologies developed by Music Unit, DeepStereo is ultra-efficient in terms of required computing power and can be easily integrated into all types of hardware and software environments.

Available in software or hardware version, DeepStereo comes in two versions:
  • DeepStereo Upmixer – for mono or stereo source files
  • DeepStereo Multichannel – for multichannel source files (5.1, 7.1, 7.1.4, Ambisonics)

Using a binaural synthesis process, the DeepStereo Upmixer plugin transforms in real time any mono or stereo audio content into universal 3D audio media compatible with any standard two-channel listening system, without altering the original timbre.

Its use is extremely simple, and applies equally well to an instrument track or group of instruments, as to the master section of a mix or mastering.  By combining just two settings - “Sphere” and “Contour” - you can adjust the spatial immersion effect, from subtle dosage to total envelopment.

Available on May 7th 2025 in VST3, AU and AAX formats, for Windows and MacOS.

SPAT Multichannel is for artists, producers and sound engineers who want to get the most out of their studio or concert hall multichannel setup. It comes with all the plugins from the Stereo version, with additional features to program up to 32 speakers. It also includes a bonus tool, Speaker Editor, which allows you to reproduce your speaker setup in Live.

SPAT Stereo is for those who have classic stereo setups (speakers, headphones) and still want to integrate high-level spatialization techniques into their productions – whether it’s creating binaural sounds on headphones or using the transaural panning algorithm with studio monitoring. The pack includes stereo versions of all the plugins that make SPAT Devices a powerful technology: Spatial, Room and Multiverb.

The result of cooperation between Leson and NOUS Digital (Austria), the Sonic HR is specially designed for use in cultural venues such as museums and exhibition halls. It enables the creation of hyper-realistic sounds thanks to binaural rendering of a quality never achieved before. Thanks to MBK software, Sonic HR headphones can render spatial sound of exceptional intensity, transporting listeners moving freely through space into a whole new listening experience.
  • Best user acceptance → preferred solution in 80% of cases!
  • Better audio quality and source localization
  • True 6DoF implementation
  • Lower latency
  • Lighter, more comfortable device

Inside the sound

Services

Design

Our teams are able to support you with sound design and solution issues.
Sound design defines sound creation applied to all areas where thinking, making and integrating sound is essential: arts, industry, urban planning, architecture, multimedia, marketing. Its multiple objectives aim, through the sound dimension, to improve the characteristics of an industrial object or an architectural space with the aim of promoting perception, accessibility and performance.
Our solution design is based on C-K theory and design thinking. This creation approach favors a co-creation process, emphasizing the functionality and form of services from the point of view of all users: the end user (your client) and the internal user (you and your team). This method allows you to identify the solution best suited to your needs, taking into account the context, constraints and stakeholders.
