About Me

Clément Gaultier

Clément Gaultier

Welcome to my webpage. My strong insterest in sound, acoustics or hearing drove me towards graduate studies specialized notably in acoustics and a PhD specialized in audio signal processing. My research topics mainly comprise solving acoustic and audio signal processing inverse problems. During my PhD I had been working on declipping and denoising using analysis/synthesis sparse priors. I also worked on binaural sound source localization with massive regressions machine learning techniques. Additionally, I am really interested in the auditory system and topics such as augmented hearing, speech enhancement or hearing protection.

My CV


You will find below a short description of my last positions and academic degrees.

Orange Labs

Since September 2019, I have been working as a postoctoral researcher with Orange Labs (R&D division of the Orange group) on multichannel acoustic echo cancellation for distributed audio systems and interpersonal communication.

Current position
Postdoctoral researcher

PANAMA team (IRISA - Inria/CNRS)

From February to August 2019, I worked as a research engineer for Inria mainly on audio restoration algorithms (multichannel declipping, pop/burst noise removal...).

Feb. 2019 - Aug. 2019
Research engineer

PANAMA team (IRISA - Inria/CNRS)

In January 2019, I graduated from Université de Rennes 1 where I did my PhD in the IRISA lab (the Panama team - a joint project team between Inria and CNRS). My main research interests were inverse problems in audio & acoustic signal processing.

Nov. 2015 - Jan. 2019
PhD Candidate

Hearing and Balance Centre (ISVR - Southampton University)

During this research stay, I studied auditory adaptation to noise for improved speech perception. The focus was finding noise characteristics and aclimatization time-scales for enhanced speech perception. For that I designed and conducted different listening experiments on 33 volunteers with normal hearing.

Mar. 2015 - Sep. 2015
Engineer in training / Master thesis

French Graduate Engineer (ENSIM)

In November 2015, I graduated from ENSIM, an engineering school in 5 years under the authority of the French Ministry of Education and Research. I specialized in Acoustics, Vibrations, Sensors.

Nov. 2015
Post graduate Student

University of Le Mans Master of Science (Research M.Sc in Acoustics)

In November 2015, I also graduated from Le Mans Université, as I was following a double degree (Research M.Sc specialized in acoustics).

Nov. 2015
