Real Time Audio Spectrum Analyzer with Signal Generator

FFT Window type

FFT analysis is a fairly complex numerical algorithm stated in literature as "the most important numerical algorithm of our lifetime". The results of a FFT analysis can be graphically presented in many ways, depending on the analysis request. EasyRTA has the most important FFT "windowing" algorithms, such as Hann (Hanning), Hamming and Blackman.

A user can choose FFT windowing algorithm depending on the type of analysis. Some FFT windows can present harmonics much better than the others, some can better suppress tremble, etc.
