The Audio and Communications Signal Processing Group (GTAC) belongs to the Institute of Telecommunications and Multimedia Applications (iTEAM) of the Universitat Politécnica de Valencia (UPV). The iTEAM is a research centre integrated in the Polythecnic City of Innovation, one of the two big scientific parks located at Valencia city.

GTAC focuses its research in signal processing algorithms used in sound and wireless communication applications. Since 1998, GTAC members have managed / participated in different research projects related to Active Noise Control systems, Sound quality perception, Spatial Audio rendering and Multi-channel audio filtering in the area of sound processing, and related to Efficient MIMO receivers, Multi-user communications and coordinated systems in the area of wireless communications. Achieved advances in these fields are available through the publications listed in the publications menu.

Currently, GTAC is leading the use of General Purpose Graphics Processing Units (GP-GPUs) to real-time multichannel processing where efficient and computationally inexpensive signal processing algorithms are needed. For this purpose GTAC is collaborating with the Interdisciplinary Computation and Communication Group of the Universitat Politécnica de Valencia in several projects.

The GTAC laboratory comprises several facilities as a large listening room (40 m2), totally equipped with audiovisual and control instrumentation. 34.560 impulse responses measured in this listening room can be downloaded here, where the configuration of the loudspeaker and microphones is depicted.
