Wind noise measurement

A non-transitory computer readable medium comprising computer program code means to make a computer execute a procedure for wind noise measurement, the computer program product comprising:

• computer program code means for, based on a control signal, obtaining a first signal and a second signal from at least two microphones, the first and second signals reflecting a common acoustic input, and the first and second signals being selected, in response to the control signal, to be either first and second temporally distinct signals each obtained from the same one of the at least two microphones, or first and second spatially distinct signals obtained from two of the at least two microphones;
• computer program code means for processing the first signal to determine a first distribution of the samples of the first signal;
• computer program code means for processing the second signal to determine a second distribution of the samples of the second signal;
• computer program code means for deriving from a difference between the first distribution and the second distribution a scalar non-binary metric reflecting an intensity of wind noise present in the first and second signals;
• and
• computer program code means for outputting the scalar metric.

A method for measuring wind noise, the method comprising:

• based on a control signal, obtaining a first signal and a second signal from at least two microphones, the first and second signals reflecting a common acoustic input, and the first and second signals being selected, in response to the control signal, to be either first and second temporally distinct signals obtained from the same one of the at least two microphones, or first and second spatially distinct signals obtained from two of the at least two microphones;
• processing the first signal to determine a first distribution of the samples of the first signal;
• processing the second signal to determine a second distribution of the samples of the second signal;
• deriving from a difference between the first distribution and the second distribution a scalar non-binary metric reflecting an intensity of wind noise present in the first and second signals;
• and
• outputting the scalar metric.
