Abstract
A system and method for on-site calibration of a plurality of microphones in a three-dimensional space are provided. The method includes causing a generation of a plurality of transmissions; causing each microphone to capture each transmission, wherein one of the microphones is selected as a reference microphone; estimating, for each microphone, a plurality of location pointers based on the captured transmissions, wherein each location pointer represents a time difference between the microphone and the reference microphone; determining, based on each location pointer, at least one location parameter for each microphone; and calibrating the plurality of microphones based on the at least one location parameter.

A method for on-site calibration of a plurality of microphones in a three-dimensional space, comprising:
- causing a generation of a plurality of transmissions;
- causing each microphone to capture each transmission, wherein one of the microphones is selected as a reference microphone;
- estimating, for each microphone, a plurality of location pointers based on the captured transmissions, wherein each location pointer represents a time difference between the microphone and the reference microphone;
- determining, based on each location pointer, at least one location parameter for each microphone;
- and
- calibrating the plurality of microphones based on the at least one location parameter.
A system for on-site generation of parameters for a plurality of microphones in a three-dimensional space, comprising:
- a processing unit;
- and
- a memory, the memory containing instructions that, when executed by the processing unit, configure the system to:
- cause a generation of a plurality of transmissions;
- cause each microphone to capture each transmission, wherein one of the microphones is selected as a reference microphone;
- estimate, for each microphone, a plurality of location pointers based on the captured transmissions, wherein each location pointer represents a time difference between the microphone and the reference microphone;
- determine, based on each location pointer, at least one location parameter for each microphone;
- and
- calibrate the plurality of microphones based on the at least one location parameter.
