Executive Summary
This project is a music visualizer implemented on a 10x10 LED matrix controlled by Beaglebone Black, where a pattern that corresponds to the spectrum of a wav file is displayed on the LED. We are able to compute the spectrum of slices of the given wavefile, convert the spectrum to a 10 by 10 matrix, and display the spectrum on the LED matrix. Currently, the LEDs updates every second. Depending on the size of the file, it may take a long time (about 1 minute for a 7M wav file) to parse the file and compute its spectrum. The project also does not involve playing the sound file and synchronizing it with the display. Adjustments can be made to change the design of the display pattern, and how often the screen is updated.

Packaging
The LED matrix is a 3-pin device that connects directly to the beaglebone.

If you have hardware, consider Small Build, Big Execuition for ideas on the final packaging.

Installation Instructions
Give step by step instructions on how to install your project.


 * Include your github path as a link like this to the read-only git site: https://github.com/MarkAYoder/gitLearn.
 * Be sure your README.md is includes an up-to-date and clear description of your project so that someone who comes across you git repository can quickly learn what you did and how they can reproduce it.
 * Include a Makefile for you code.
 * Include any additional packages installed via opkg.
 * Include kernel mods.
 * If there is extra hardware needed, include links to where it can be obtained.

User Instructions
Once everything is installed, how do you use the program? Give details here, so if you have a long user manual, link to it here.

Highlights
Here is where you brag about what your project can do.

Include a YouTube demo.

Theory of Operation
The software reads a wave file, and obtains the amplitude and the sampling frequency. The amplitude is sliced into one second segments, and fast Fourier transform is performed on each fragment to obtain the spectrum of each second of the wav file. For each spectrum, the frequency component is divided into ten columns, and the amplitude is normalized to a value between 0 or 10. This 10x10 matrix is displayed on the LED matrix using open pixel control.

Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.
