Abstract
A method for removing a target unwanted signal from multiple signals. The method includes: providing a set of input signals from external devices; separating the input signals into channels with the unwanted signal and channels without the unwanted signal; synchronizing the sets of input signals; and transferring the separated signal via wire or wirelessly to a sound reproduction device.
Claims15
A method, comprising:
- providing a set of input signals from external devices;
- separating the input signals into channels with unwanted signals and channels without unwanted signals;
- synchronizing the sets of input signals;
- and
- transferring separated signal via wire or wirelessly to a sound reproduction device.

A system for removing a target unwanted signal from multiple signals, the system comprising:
- a set of input units from external devices for inputting at least two input signals;
- a processor;
- and
- a memory, the memory adapting to store computer readable instructions which when executed by the processor, cause the processor to:
- maximize and maintain the independence of the sets of input signals;
- extract the coefficients to maximize the independence among the input signals;
- detect a noise segment from one direction or all potential directions;
- detect the relative position between the microphones and reproduction device, so as to adjust the direction real-time;
- synchronize the sets of input signals;
- separate the sets of synchronized input signals into channels with unwanted signal and channels without unwanted signal;
- and
- select the optimal channel without unwanted signal as Output signal intelligently.
