Making sense of sound - Digital Audio Processing Lab at IIT Bombay

Preeti Rao of the Indian Institute of Technology Bombay is an expert in sound processing—an approach that helps us do various useful things, one of which is removing unwanted sounds (or noise) from an audio clip. With her team at the Digital Audio Processing Lab, Prof Rao attempts to understand the nature of sound, reveal the information it may hold, and use it for, say, identifying tracks, melodies or the raga of a song. Prof Rao’s team works on the analysis of sound to recognise tone, pace and stress on words, and algorithms to reduce noise in audio signals. The team has developed various useful applications, such as teaching aids for learning a new language and a mobile app to evaluate children’s understanding of the text while reading.
