Audio Spectrum Analyzer. This is a real time LED Audio Spectrum Analyzer. You can embed this unit in an audio system or use it as a stand-alone unit. The LED Spectrum Analyzer can display a real-time bar-graph spectrogram on a 20 x 20 LED display in four different ways. It produces very nice visual effects and simultaneously provides an ...
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.
