Abstract
Methods and systems are provided for enhanced audio experiences in VR/AR applications. The apparatuses of this disclosure are adapted to record multiple binaural stereo pairs and play back select binaural pairs corresponding to users' head positions. A substantially spherical microarray is utilized in various embodiments for recording multiple binaural stereo pairs. A VR/AR headset is further adapted to track a user's head positions and dynamically play back binaural sound pairs corresponding to the head positions.
Claims8
An apparatus for binaural sound recording, comprising:
- a substantially spherical microphone array adapted to record multiple binaural sound pairs;
- and a multi-channel recording processor adapted to process the multiple binaural sound pairs thereby producing multiple pairs of binaural audio, wherein the substantially spherical microphone array comprises a substantially spherical frame whose orthodromes have a diameter substantially the same as the distance in between a pair of human ears and a plurality of microphones affixed to the surface of the frame at the orthodromes, wherein each of the plurality of microphones on an orthodrome is paired with a microphone on said orthodrome at its opposite side for recording binaural sound pairs, and wherein a virtual reality and augmented reality (VR/AR) ear set is adapted to receive the multiple binaural sound pairs and a head position from a VR/AR head set.
A virtual reality and augmented reality (VR/AR) system for providing enhanced audio experiences to a user, comprising:
- a VR/AR headset adapted to track the user's head positions;
- a VR/AR ear set connected to the VR/AR headset and adapted to retrieve head positions of the user from the VR/AR headset;
- a substantially spherical microphone array adapted to record multiple binaural sound pairs;
- and, a multi-channel recording processor adapted to process the multiple binaural sound pairs thereby producing multiple pairs of binaural audio, wherein the substantially spherical microphone array comprises a substantially spherical frame whose orthodromes have a diameter substantially the same as the distance in between a pair of human ears and a plurality of microphones affixed to the surface of the frame at the orthodromes, wherein each of the plurality of microphones on an orthodrome is paired with a microphone on said-orthodrome at its opposite side for recording binaural sound pairs, and wherein the VR/AR ear set is further adapted to receive the multiple binaural sound pairs and dynamically reproduce a binaural sound pair corresponding to the head position.
