Sound processing is fundamental to many of our every-day appliances such as noise-cancelling headphones, hearing aids, as well as emerging technologies such augmented and virtual reality. For the noise reduction to be effective or for the virtual world to sound realistic, we need accurate descriptions of the acoustics of the surrounding space. However, as you move around a room, the acoustics change as the path the sound takes changes. This poses a big challenge for sound processing applications as this implies that you would have to measure the acoustics of every inch of the room. In this project, we aim to overcome this by developing tools that allow for computing complete acoustic description from just a small number of measurements. This is done by creating a framework for comparing and interpolating acoustic properties using the concept of optimal transport. The project will not only provide researchers with powerful tools but will also pave the way for improved consumer products.
