Abstract
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.
Claims24
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.
A system for encoding a sound field comprising:
- an orientation detector to detect one or more indications of the orientation of a first computing device;
- a microphone selector to select one or more microphones from a plurality of microphones located on sides of the first computing device responsive to the one or more indications of the orientation of the first computing device;
- and
- a sound field encoder to encode a sound field received by the selected microphones through inclusion of descriptive information with the encoded sound field indicative of 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 indicative of the orientation of the first computing device.
