This is realted to my previous traversal “ An Easy way to compare two audios “. 1. First convert both audio file into .wav if they are in mp3 or any other format. 2. Then convert time-domain .wav files into frequency-domain data by Fast Fourier Transformation (FFT). The Fourier Transform proposes to decompose any signal into a sum of sin and cos. In this process, a …

1 In general, the FFTs for the complete file will not be equal - consider a 40 sec. file that contains four 10 sec. segments of sine waves at 20Hz, 40Hz, 60Hz and 80Hz, respectively. The corresponding spectrum for the whole file would show peaks at those four frequencies, but any 10 sec. excerpt would have two of them at most.

Hello, I am trying to compare two similar audio files (WAV). From what i have read i need to sample both audio files at certain frequencies and run these through a FFT and then compare the results. Can anyone advise me if this is the correct approach and also describe the steps i need to take to get to the stage where I can compare the files.

A quick and simple way to compare audio files. Take the audio file, make a copy, in a daw, paste them side by side, in 2 stereo channels, invert the phase on one of the stereo tracks, align both of the file at the beginning in zoom mode, be sure that the both files have same amplitude at the beginning, then play ,if there's total silence, then both files are identical, if there's a difference …

Initialize the AudioAnalyzer instances input_sr stands for input sample rate, and is set to 44100 for each file. We also have fft_size set to 44100. FFT is basically a way of taking time domain data and creating a specified number of bins in which to place frequency information.
