Create and view the fourier transform of an audio file
Version: 0.1Soundwave is a visualization of the fourier transform applied to sound data. Soundwave analyzes a time-domain sound sample using the Fourier Transform, and graphically displays the results and sound in real time.
Operating System: Mac OS X
Soundwave takes a fourier transform of a very short (a few milliseconds) clip of your audio file. That converts the time-domain data to frequency domain data. The data is then converted into a colored stripe with each pixel representing a different frequency, and the color of the pixel representing the amplitude of the frequency. This is done many times and is scrolled across the screen. The result is a graph of time versus frequency versus amplitude. When scaled correctly this graph resembles actual sheet music.
