Open Source Java Data Management Systems for Android

MusicDNA is a music player unlike any other. It is an Android music player that renders beautiful DNA (visualization) of the currently playing music. It does this through the use of the Visualizer Class, and is inspired by paullewis's music-dna. It uses the FFT Data supplied by the Visualizer class of Android , calculating the Amplitude at that exact moment and using this to plot the DNA. MusicDNA fuses the functionality of traditional music players with stunning visualizations. In this way it captivates not only the sense of hearing but the sense of sight as well. MusicDNA's player allows for playing both local music as well as streamed music from SoundCloud.
