DIGITAL AUDIO PROCESSING 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, recording and listening equipment. The interdisciplinary flavour of several of the projects has stimulated many interactions with musicians, musicologists and language experts. Further, audio IP developed in the lab has been incorporated into a few products and services for the entertainment industry.
