FFT Spectrum Live Wallpaper

FFT Spectrum Live Wallpaper. Shows FFT analysis of live music.

Edit: October 31 2015 - Added detailed purpose of app. Sorry I have not had time to work on this.

This is a simple yellow and red wallpaper that shows the frequency spectrum of the music you're playing.

It's not configurable and may not work well or at all with some devices.

Some devices seem to need a restart for the listening service to work.

The math (low pass filters, frequency range) is also geared to my personal tastes.

It uses Android's MusicVisualizer library for the heavy lifting, and thus may not support some devices' bluetooth players (and other music players).

If anyone knows of a free application that will show a FFT (frequency/spectrum analysis) of the music currently playing (ex. from Spotify), let me know. This is EXACTLY why I made this app -- to enjoy awesome violin solos. I would very much prefer to use a professional's work myself and will link it here if you tell me about it. I myself used to have an app that was much better coded which came default with the Samsung phone.

About the lack of updates: I have a day job, and nobody would pay big bucks for this anyway. If you want the source code, e-mail me and I will dig it up and upload to github.
