Abstract
A mesh map of networked radio devices is maintained for recording audio of a target speaker using multiple radio devices. Relative locations of the radio devices are established according to audio signal quality received by the radio devices. A primary microphone assignment for recording the target speaker is dynamically assigned among the radio devices according to audio quality conditions. Additional roles of background audio microphone and speaker system may be assigned to other nearby radio devices.
Claims20
A computer-implemented method comprising:
- identifying a plurality of radio devices for role assignment;
- locating a target speaker based on audio signal quality received by the plurality of radio devices;
- establishing a mesh map of the plurality of radio devices based on shared audio signal data from the plurality of radio devices, the mesh map locating a first device with respect to other devices;
- and
- assigning to the first device a role of primary microphone, the first device receiving a higher quality audio signal of the target speaker than the other devices.
A computer program product comprising a computer-readable storage medium having a set of instructions stored therein which, when executed by a processor, causes the processor to perform a method comprising:
- identifying a plurality of radio devices for role assignment;
- locating a target speaker based on audio signal quality received by the plurality of radio devices;
- establishing a mesh map of the plurality of radio devices based on shared audio signal data from the plurality of radio devices, the mesh map locating a first device with respect to other devices;
- and
- assigning to the first device a role of primary microphone, the first device receiving a higher quality audio signal of the target speaker than the other devices.
A computer system comprising:
- a processor set;
- and
- a computer readable storage medium;
- wherein:
- the processor set is structured, located, connected, and/or programmed to run program instructions stored on the computer readable storage medium;
- and
- the program instructions which, when executed by the processor set, cause the processor set to perform a method comprising:
- identifying a plurality of radio devices for role assignment;
- locating a target speaker based on audio signal quality received by the plurality of radio devices;
- establishing a mesh map of the plurality of radio devices based on shared audio signal data from the plurality of radio devices, the mesh map locating a first device with respect to other devices;
- and
- assigning to the first device a role of primary microphone, the first device receiving a higher quality audio signal of the target speaker than the other devices.
