Abstract
A signal processing apparatus includes an adder that acquires a plurality of input signals from a plurality of microphones and calculates an added value obtained by adding the input signals together, a subtracter that acquires a plurality of input signals from the plurality of microphones and calculates a subtracted value obtained by subtracting one input signal from the other input signal, and a determination unit that determines whether noise is included in the input signals based on the added value and the subtracted value.
Claims12
A signal processing apparatus comprising:
- an adder that acquires a plurality of input signals from a plurality of microphones and calculates an added value obtained by adding the input signals together;
- a subtracter that acquires a plurality of input signals from the plurality of microphones and calculates a subtracted value obtained by subtracting one input signal from the other input signal;
- and
- a determination unit that determines whether noise is included in the input signals based on the added value and the subtracted value.
A signal processing method comprising:
- acquiring a plurality of input signals from a plurality of microphones and calculating an added value obtained by adding the input signals together;
- acquiring a plurality of input signals from the plurality of microphones and calculating a subtracted value obtained by subtracting one input signal from the other input signal;
- and
- determining whether noise is included in the input signals based on the added value and the subtracted value.
A computer-readable recording medium having stored therein a program for causing a computer to execute a signal processing procedure comprising:
- acquiring a plurality of input signals from a plurality of microphones and calculating an added value obtained by adding the input signals together;
- acquiring a plurality of input signals from the plurality of microphones and calculating a subtracted value obtained by subtracting one input signal from the other input signal;
