Re: plotting amplitude and frequency of a sound file. 13 Years Ago by JamesCherrill Fourier Transform is what gives you amplitude vs frequency from an amplitude vs time (waveform) source. FFT is "fast fourier transform" - a computer algorithm for doing FT's quickly.

And from the names in the code there, I'm guessing it has something to do with fourier transforms? Re: download java applet 18 Years Ago by topito2 That's correct. It is related to Fourier Transforms. Well, I'm not interested in the code. I'm interested in the applet itself.
