The Audio and Communications Processing Group (GTAC) is a leader in developing digital signal processing algorithms for sound and wireless communication applications.
Since 1998, GTAC members have spearheaded research projects on active noise control, personal sound zones, spatial audio perception and representation, psychoacoustics, and sound quality enhancement. Many of these projects have been implemented on multichannel audio systems (using microphone and speaker arrays) and combined with innovative parallel processing techniques on multicore processors and GPUs. Recently, GTAC has been leveraging Artificial Intelligence in its audio solutions, including sound event detection, classification, and localization. Its communications expertise includes efficient MIMO receivers, multiuser communications, coordinated mobile communication systems, multichannel adaptive filtering, and wireless acoustic networks.
Additionally, the GTAC laboratory features a 40 m² acoustically treated room, fully equipped with professional audiovisual and control instruments. It also houses a perceptual spatial sound laboratory capable of measuring personalized head-related transfer functions (HRTFs), enabling immersive sound reproduction in the most current formats.
