Nicolas Lopes

Audio Consultant Expert | DSP, Acoustics & Control

Ex-Manager at Devialet | PhD IRCAM | 13 Years Experience

Available for freelance projects

I help companies solve complex challenges in signal processing, control systems, and acoustics, from concept to market release.

Freelance consultant specializing in DSP, control, and audio systems with 13 years of experience. My background combines deep expertise in premium audio (8 years at Devialet on world-renowned products: Mania, Dione, Phantom Ultimate) with strong fundamentals in signal processing, nonlinear control, and adaptive systems applicable to diverse engineering domains.

APPROACH

I cover the entire development chain: from system architecture and mathematical modeling to custom algorithm design, embedded implementation, and final validation. While audio is my primary domain, my PhD-level expertise in control theory and signal processing allows me to tackle challenges in acoustics, vibration, mechatronics, and other applications requiring advanced DSP and control.

Rare dual expertise: high-level academic research (PhD from IRCAM in control and modeling) combined with industrial experience on premium and mass-market products.
