Sound field encoder

摘要

In a system and method for encoding a sound field the orientation of a computing device may be detected. Several orientation indications may be used to detect the computing device orientation. The detected orientation may be relative to a sound field that is a spatial representation of an audible environment associated with the computing device. Microphones associated with the computing device may be selected in order to receive the sound field based on the detected orientation. The received sound field may be processed and encoded with associated descriptive information.

主权项

1. A computer implemented method for encoding a sound field comprising:
detecting one or more indications of the orientation of a first computing device; selecting one or more microphones from a plurality of microphones that are on sides of the first computing device responsive to the indications of the orientation of the first computing device, the plurality of microphones including at least two microphones on one side of the first computing device; and encoding a sound field received by the selected microphones by associating descriptive information with the sound field indicating the orientation of the first computing device, wherein a second computing device is configured to select audio transducers to reproduce the sound field based on the descriptive information indicating the orientation of the first computing device.
