Matthieu Leroy
Also known as Mamat
Chief sound operator · Sound system engineer · Trainer
Chief sound operator at Radio France since 2001, from studios to outside broadcasts, with international touring experience across the Americas. My focus: prepare, make it work and share what I know.
As a kid, I wanted to be either a sound engineer or Michael Jordan. My basketball career clearly didn’t work out. I stuck with sound.
WHAT I DO
Sound, systems and people.
Systems & networks
Sound reinforcement design, measurement and alignment, audio networks and intercom. Bringing consoles, audio transports and control tools together into a working system.
Technical coordination
Scoping, preparation and coordination of teams and suppliers through to operation. Anticipating constraints, managing interfaces and documenting decisions.
Training & knowledge sharing
Helping technicians and operators understand sound systems, audio networks, measurement and working methods. Explaining why as well as how, through practical situations.
PROFESSIONAL BACKGROUND
From the studio to the touring stage.
Since 2001Radio France
Chief sound operator & technical project coordination
A background spanning studios, postproduction, reporting, concerts and outside broadcasts. I design and coordinate technical setups from preparation to operation, working with stage teams, control rooms and suppliers. Projects include France Inter’s Fête de la musique concerts at the Olympia and the Victoires de la musique classique.
2015 — 2018Mexico & the Americas
Sound system engineer on international tours and events
During two periods of leave, I worked independently across the Atlantic. My role covered designing and deploying sound reinforcement systems, coordinating preparation, installation and operating teams, and training staff in sound systems, networks and measurement.

LEARNING & SHARING
Keep learning. Share what works.
I train and support teams using the systems they operate. My own training also continues: audio, networks, design tools and teaching methods.
Sound reinforcement systems & workflows
Qualified across different systems and working methods, including L-Acoustics, d&b audiotechnik and Adamson: design, simulation, deployment, measurement and alignment.
Audio network engineering
Audio network design and operation, routing, synchronisation and redundancy: Dante, AVB and SMPTE ST 2110. Connecting the requirements of live sound, control rooms and broadcast.

Why I build SiLeMI/O
My work in live sound is the starting point for a broader question: how can we make tools we can adapt as our work changes?
