Abstract
Embodiments of the invention relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and wearable computing devices to facilitate production and/or reproduction of a spatial sound field and/or one or more audio spaces. More specifically, disclosed are systems, components and methods to determine acoustically positions of audios sources, such as vocal users, for providing audio spaces and spatial sound field reproduction for remote listeners. In one embodiment, a media device includes a housing, transducers disposed in the housing to emit audible acoustic signals into a region including one or more audio sources, acoustic probe transducers configured to emit ultrasonic signals and acoustic sensors configured to sense received ultrasonic signals reflected from an audio source. A controller can determine a position of the audio source.
