Following is a partial FFT result. I want to extract the dominant frequency out of it. Freq. Real Im. ... 437 40.004 -123.185 438 59.129 -182.045 439 113.026 -347.923 440 1244.858 -3831.345 441 -138.493 426.170 442 -65.685 202.089 443 -43.090 132.547 ... In this case, I know the solution, it's a perfect f=440.1Hz re=0, im=-4096. Is there an algorithm to find this value ?
