CT-gui is a touch-friendly GUI toolkit which can be used on the Linux desktop and on Android devices. Development can be done quickly and easily on a Linux box and then installed to an Android tablet or phone. For graphics, only OpenGL or OpenGL ES is used. For audio, ALSA is used for Linux and OpenSL ES for Android. For development, the Android SDK and NDK should be installed on your system. Two demo projects called CT-synth and CT-farfisa are included, which are a polyphonic synthesizer with built-in patches, and an organ with many sounds. These can be played using the mouse or your fingers, or with an attached MIDI keyboard. For direct download to an Android device, 2 apk files are provided.

PASAP runs in the background, checking whether a stream exists, and, if it does, plays it. It was originally written to play back audio provided by MPD in remotely networked locations, but it also allows consumer-grade HD decoders (WDTV) to automatically play back audio/video streams from an HTTP address.
DeaDBeeF is an audio player for GNU/Linux and other UNIX-like systems. It is written in C with some plugins in C++. It has minimal dependencies, a native GTK2 GUI, cuesheet support, support for MP3, Ogg, FLAC, and APE, chiptune formats with subtunes, song-length databases, and more. It is very fast and lightweight, and extensible using plugins (DSP, GUI, output, input, etc.). The GUI looks similar to Foobar2000.
