SquareDeskPlayer is the newest version of SquareDesk, a fully-featured music player (and eventually lyrics editor), designed for square dance callers and round dance cuers. SquareDeskPlayer contains a powerful MP3 player with independent pitch and speed controls, a quick-search facility, and a 3-band equalizer. It will eventually be merged with the MP3 Lyrics Editor shown below, which will provide singing call lyrics (and round dance cues) editing, karaoke-like dynamic highlighting, and more. Once I reach the V1.0 milestone, the code will be released as Open Source under a suitable license, so that others can develop new features as well.
Here’s a quick PDF introduction to SquareDeskPlayer.
