Hi everyone ;
I am trying to do sound localization with two microphones project . I have found many methods but I think correlation method is most fits to my problem .
My logic is, I have samples from microphones and correlation coefficient function works even the sound source doesn’t hit the microphones.
When the sound source hits the microphones it will change the samples and the correlation coefficient . I need to calculate the difference between the correlation coeff. which the sound source does not hit the microphones and coefficient that sound source hit the microphone .
I need to calculate d from d=c (speed of sound)*time differance (t) and I am going to apply trigonometric functions to find the angle of the sound source and find its location.
Can I find the time difference between those two correlation coefficients ?
( my sound source will be at fixed frequency and it will come continuously.)
Thank you for any help and sorry for my English)
