How to get spectrum of audo file using mexican hat

22 May 2017 by Rick York

The usual technique for obtaining the spectrum of a signal to use a Fourier transform, most often the FFT. There is one example program at this page[^]. By the way, you might prefer to include math.h with the macro _USE_MATH_DEFINES defined. That file has definitions of most common...

C# FFT Algorithem not working properly

22 Jan 2016 by DANIEL_PD

Hello guys,I'm having a problem with my coding. Currently I am working on a evaluation tool. This tool has to do some frequency analysis. Therefore I bought a book and read quite some articles about the FFT in C# and finally got some code to calculate it.For a small amount of samples, e.g....

How to get spectrum of audo file using mexican hat

22 May 2017 by Member 12464144

I have a sound file with the extension wav. I got the amplitude values of this file. Then I generated values of Mexican hat wavelet using y = (1-t*t)*exp(-1*t*t/2). Now I need to get the spectrum of this audio file. How to do this. Here is my code What I have tried: #include ...
