An Introduction to the Audio Processing Group @ UFRJ
By L. W. P. Biscainho

Luiz Buscainho (Federal University of Rio de Janeiro) gives ADASP an overview of research conducted within his group @ UFRJ.


The GPA is the audio branch of the Signal, Multimedia and Telecommunications Lab (SMT) at UFRJ, and maybe the only Brazilian research group exclusively oriented to digital audio processing. In 20 years, the research projects of GPA hosted the works of BSc, MSc and DSc students in a wide range of topics, including audio restoration, binaural auralization, time-frequency analysis, automatic audio quality assessment, sound source separation, acoustic source / acoustic sensor localization, speech recognition, automatic rhythm analysis, and many others. From their strong signal procesing origins, almost all applications have increasingly explored machine learning. This presentations begins with a zoom from UFRJ to the GPA, introduces the group, and discusses some of its research topics, with emphasis in our current interests.


Luiz W. P. Biscainho was born in Rio de Janeiro, Brazil, in 1962. He received his degree in Electronics Engineering (1985), and his M.Sc. (1990) and D.Sc. (2000) degrees in Electrical Engineering from UFRJ. Having worked in the telecommunications industry between 1985 and 1993, Biscainho is now Associate Professor in the Department of Electronics and Computer Engineering (DEL) of Poli and the Electrical Engineering Program (PEE) of COPPE at UFRJ. His main research area is digital audio processing. He is an active member of the IEEE and the AES.
