Coherence is a set of DLNA/UPnP devices, like MediaServer and MediaRenderer. In addition, it includes a well-designed framework to extend other applications with DLNA/UPnP functionality. It also has an emerging DBus API, enabling these applications to participate in digital living networks. It supports Playstation 3 (PS3), XBox, and many other devices.
DesktopLyrics is an application that displays the lyrics of the song currently playing in "iTunes" right on your desktop. The lyrics for the song have to be set in iTunes; DesktopLyrics does nothing to fetch them if they aren't available in iTunes. If you don't want to set all your lyrics manually, you can use an application like "Harmonic".
Festival is a general multi-lingual speech synthesis system developed at CSTR. It offers a full text to speech system with various APIs, as well an environment for development and research of speech synthesis techniques. It is written in C++ with a Scheme-based command interpreter for general control.
The festvox project, based at Carnegie Mellon University, distributes documentation, scripts, and examples that should be sufficient for an interested person to build her own synthetic voices in currently supported languages or new languages in the University of Edinburgh's Festival Speech Synthesis System. The quality of the result depends much on the time and skill of the builder. For English, it may be possible to build a new voice in a couple of days' work; a new language may take months or years to build.
Fripp is a music composition environment that uses a spreadsheet metaphor for entering music and manipulating it with built-in and user-created functions. It supports MIDI playback and recording, and displays music in common notation. Scores can be exported to Mup format for high quality printing. The core program is written in Python, and the user interface is implemented using the wxPython toolkit.
Hayes is the playlist for Noatun that attempts to be efficient for those users with large directories full of music, especially directories futher organized by album. For these users, Hayes should be more efficient in speed and memory than the usual playlist. Plus, the playlist is updated in realtime as the directories change on-disk, so playlist maintenance is no longer an issue. For everyone else, Hayes has some nice features, too: full integration with the KDE global "MetaInfo" system for generic handling of tag information, a fully KDE-standard user interface, proper shuffle behavior with a history, multiple sort modes (including a drag-reorderable custom sort), and nifty checkboxes that let you turn particular files or directories on/off. Two-way Konqueror integration adds convenience to playback and file management. All playlist data is stored in .directory files, which are easily readable and reusable by other applications and tools.
MPy3 is a full-featured, modular, configurable MP3 player system aimed at jukeboxes or car MP3 systems. It can play MP3s via rxaudio or mpg123, take input from a keyboard (tty), LIRC, or joystick. It does output through a CrystalFontz LCD directly, or through any LCD that LCDProc supports, or even through X. It features playlist support and support for controlling the mixer (using aumix). All of the inputs, outputs, and other functions are controlled via a number of modular libraries which can be used in other projects as well.
