Abstract

Using signal processing and recording with numerous microphones, a sound field can be decomposed into its attributes such as original sound source signals, sound source positions, directivity of sound sources, early reflections, and late reverberation. Sound field editing would be highly versatile after such decomposition. Moreover, the original sound field and a modified sound field can be synthesized flexibly by modifying and exchanging attributes. We designate such a system as an editable sound-space system. To realize such systems, we are developing signal processing techniques to decompose such properties from recorded sound based on a surrounding array of 157 microphones. After introducing this system, this report describes the estimation of source positions, original sound source signals, and directivity of sound sources.
