About us

Sound is an essential media containing a variety of information, and in everyday life, we communicate with speech, enjoy music, and perceive various situations around us through sound. Aiming to realize the advanced acoustic information processing similar to or exceeding that of humans, TMU-Ono Lab is working on signal processing and information processing for sounds. With focusing on microphone array signal processing, our recent research topics are low-latency real-time sound source separation, asynchronous distributed microphone arrays, sound-to-light conversion devices "Blinky", acoustic scene recognition, analysis of autism spectrum disorder speech, and so on. We are working on a wide range of studies from theory to real-world applications. Demo movies are here.
