The resulting graph is known as a spectrogram.
Audio Spectrum Analyzer Final Report
http://pages.hmc.edu/harris/class/e155/projects03/volume.pdf
Our final project was to build a simple audio spectrum analyzer. The device will take line-level stereo audio input and display the spectrum on a bank of LED arrays. There will be seven frequency bands for both the left and right channels for a total of 14 bands. The first major element of our system is the input processing section.

The frequency meter circuit is the one about a Wien bridge which often when employed for frequency measurement provides the form displayed below:- If Cx = Cs Rx = Rs, and Rb = 2 π then f = 1 / 2 πCs Rs or Rx = Rs = 0.628 f where c. = C, = 0.1µf. Our calibration chart was worked out using this last formula.
