Binaural reproduction from microphone array recordings
Binaural reproduction is a spatial audio technology that reproduces sounds at two ear positions by using headphones and head-related transfer functions (HRTFs). The binaural sounds in a VR space are simply reproduced by numerical acoustic simulations using given source positions and signals. However, the binaural reproduction of a real environment is not straightforward. We develop a technology to estimate a sound field using a microphone array and reproduce it as binaural sounds, which can be applied to VR systems requiring a large listening area.
