Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to get a plot of the sound's magnitude vs. frequency. I have managed to read in a wav file as a matrix. I then compute the fft of this matrix. When I plot the absolute value of this, I get a symmetric plot with peaks at the start and the end. What is this a plot of? Is it magnitude vs. frequency? Someone please help, I'm really confused! Any help would be much appreciated!
