Abstract
In this paper we describe the sound wave signal analysis using Fast Fourier Transform application in Matlab. Firstly we know some important application and definition as shown in example i.e. Fourier series, Fourier transform (FT), Discrete Fourier transform (DFT), Fast Fourier transform (FFT) and Wavelet transform (WT) in Filter bank and also how to apply filter bank in Matlab, i.e. Normalized Filter, High-pass Filter, Low-pass Filter and also the Band-pass Filter and Band-stop Filter. That application is very useful in the study of frequency response in a Filter bank and Fast Fourier transform in the signal analysis. It describe the mathematical foundations of digital signal processing, sound, synthesis algorithms, multi-time frequency domain analysis associated with musical sound etc. Our aim is to consider two sound wave signals to analyze the frequency response of sound wave signal or in other words this paper is to compare and analyze two sound wave signals associated with Fast Fourier transform numerically and graphically
