Portrait of Sebastian Braun

Sebastian Braun

Senior Researcher


My research interests are in the field of audio and acoustic signal processing, e.g. speech enhancement and separation, microphone array processing, acoustic localization and tracking, acoustic parameter estimation, perceptual acoustics and spatial audio.

I work closely with product teams at Microsoft to develop algorithms for suppressing echo, noise, reverberation and interfering speakers, to improve captured speech signal quality and intelligibility for human and machine listeners, and to separate audio sources.
