prc utilises a pioneer control out port and a sound card to make the keypresses on a pioneer remote control available to the computer. With additional scripts or programs, it is possible to control your computer without additional hardware, like infrared receivers. It features automatic noise level detection, and it is independent from the sound architecture used.
MP3val is a tool for validating and optionally fixing MPEG audio files. It was primarily designed for MPEG 1 Layer III (MP3) files, but also supports MPEG-1, 2, and 2.5 Layers I, II, and III. It can be useful for finding corrupted files, such as those that have been downloaded. It supports ID3v1 tags (which must be at the very end of the file), ID3v2 tags (at the very beginning of the file), and APEv2 tags.
OCRFeeder is a document layout analysis and optical character recognition application. It is able to automatically outline a document image's contents, distinguish between graphics and text and perform OCR over the latter. It can export to several formats, its main one being ODT. OCRFeeder has a GTK+ graphical user interface that allows the user to control the application and, for example, edit and correct the automatic recognition. It can also be used from the command line for automation.
KPlaylistCreator is a jukebox for KDE. It scans for MP3 and Ogg Vorbis files, located in various directories, creates a unique tree view with genre, artist, album, and song title information, features a user rates mechanism, a user playlist manager, and a wizard playlist creator, edits tags for both MP3 (ID3 v2) and Ogg Vorbis files, checks directories for new and missing files automatically, sends playlists to a directory, XMMS, or to K3B, displays and sets the album art of MP3 files, creates playlists from a virtual library, and includes popup windows to indicate change of song.
The Epeios MIDI to XML converter makes it possible to convert binary MIDI files to a format that allows them to be handled effectively with tools like CVS. If you put, using your favorite MIDI sequencer, the CVS '$Id$' tag (or other CVS tags) in the comment tag of the MIDI file, the changes made to this tag by CVS are propagated into the MIDI file.
Scheme Note is a Scheme-like music file format and MIDI conversion tool. It takes a text file, which is a representation of a song, loosely tied to a MIDI-like event structure, and outputs a corresponding MIDI file. It is hand-editable for simple songs, and should be very easy to parse for a GUI.
