Introduction
Freelance audio consultant specializing in premium audio systems with 13 years of experience, including 8 years at Devialet on world-renowned products (Mania, Dione, Phantom Ultimate). I help companies tackle their toughest acoustic and DSP challenges, from design to market. MY APPROACH I cover the entire audio chain: from initial acoustic design to custom DSP algorithms, embedded implementation, and final tuning through critical listening. Rare dual expertise: high-level academic research (PhD from IRCAM in control and modeling) combined with industrial experience on premium and mass-market products. TECHNICAL EXPERTISE Audio & Acoustics - Complete audio system design and architecture - Room correction and automatic calibration - Sound spatialization - Acoustic measurements (Audio Precision, Klippel, REW) - Subjective tuning and critical listening Signal Processing & Control - Custom DSP algorithm design - Nonlinear control and adaptive observers - Electro-acoustic modeling and simulation Tools: Python, MATLAB/Simulink, C/C++, Git, Audio Precision, Klippel, REW, Max/MSP MAJOR ACHIEVEMENTS Dione (Devialet Premium Soundbar) Led complete acoustic design, DSP pipeline (spatialization, room correction), and final tuning. → "The First Soundbar An Audiophile Will Actually Want In Their Living Room" - The Music Room Mania (Devialet Premium Portable Speaker) Innovative omnidirectional acoustic architecture, AI-powered room correction, thermal management. → "The best sounding portable Bluetooth speaker I have ever listened to" - World Wide Stereo Phantom Ultimate (Iconic Product Redesign) Major phase acoustics improvement, frequency response optimization, complete DSP pipeline overhaul. → "Phantom Ultimate definitely feels like a step forward" - Smart Home Sounds International B2B Projects Direct technical collaboration with Huawei (Sound X, Sound Joy), Belkin (SoundForm Elite), Hisense (TVs) MANAGEMENT & INNOVATION Created and led the Audio System Design team at Devialet (2 → 10 engineers in 5 years) Drove technical innovation roadmap (3-5 years) to maintain technological advantage Direct technical interface with international B2B clients FREELANCE SERVICES - Technical audit and strategic consulting - Custom DSP algorithm development - Innovation & Roadmap - Audio system tuning and optimization - Room correction and calibration - Electro-acoustic simulation and modeling - Technical due diligence Format: Remote preferred, travel possible Availability: Short missions (audit) or long-term (product development) 📧 [email protected]
