About the Lab
The Digital Audio Processing Lab is a signal processing research facility dedicated to speech and audio applications. Research projects involving Ph.D. and M.Tech. students include music content analysis and retrieval, speech prosody for language learning, speech enhancement and recognition. The lab is equipped with computers, GPU servers, and recording and listening equipment. The interdisciplinary flavour of several projects has stimulated interactions with musicians, musicologists and language experts. Audio IP developed in the lab has been incorporated into products and services for the entertainment industry.
