...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.

This library is being created as I have a need to do very fast FFTs on low end devices not supporting the NEON instruction set. The Raspberry Pi is an ideal candidate for developing in gcc before porting to JNI for low spec Android devices, hence it's inclusion. Fixed point 16/32 integer FFT library suitable for the Raspberry Pi and Android devices. Includes test stubs for gcc on the Raspberry Pi and a Basic4Android wrapper from JNI. It includes hand optimised ARMv6 assembler, demonstrating techniques such as pipeline stuffing to achieve maximum performance. It also demonstrates how to include large chunks of assembler inline with C/C++ thus avoiding ABI issues between platforms.
