Abstract:
A sound signal processing method and device are provided for separating sounds of the respective sound sources even when sounds are recorded asynchronously by a plurality of devices. Specifically, the present invention comprises the steps of instructing each of the plurality of devices to output a reference signal of a different frequency, receiving each of the reference signals output from the speaker of the plurality of devices according to the instruction, receiving sound signals in which each of the reference signals output from the speaker of the plurality of devices is input into the microphone of the plurality of devices, calculating a time shift amount of each of the devices based on each of the received reference signals output from the speaker and the received sound signals, and separating the plurality of signal signals input into the microphone of the plurality of devices based on the calculated time shift amount.

Claim (Index 7):
A sound signal processing device connected to a plurality of devices including a microphone and a speaker, comprising:\n a data transmission/reception unit which sends reference signals each having a different frequency to the plurality of devices, and receives each of the reference signals output from the speaker of the plurality of devices and sound signals in which the reference signal was input into the microphone of the plurality of devices; a time shift amount calculation unit which calculates a time shift amount of each of the devices based on the output reference signals and the input sound signals; and a signal separation unit which separates the plurality of sound signals input into the microphone of the plurality of devices based on the calculated time shift amount, wherein the data transmission/reception unit sends the separated sound signals to the plurality of devices.
