Block Filter using OverLap and Save, with FFT

A block filter that implements the overlap and save method with FFT

A simple file that implements the Overlap and Save method with FFT.

Sample data (music, random numbers, sine waves) are used to demonstrate that the method works. Results of Overlap and Save method are compared to Matlab's linear filtering (filter(b,a,x)).

I will modify the file into a function and later a Gui for learning purposes
