Dancing QT is a combined music database and player application specially designed for dancing schools and equivalent applications. Key features are an easy-to-use interface, fast search capabilities, playlist management, exact pitching and crossfading.
Looking around the open source landscape for a while, I tried to find a music database and player that is suitable for use in a dancing school environment – without success. Most mixing applications tend to be too confusing for the intended audience, most players lack database searching capabilites and most song databases don’t know how to pitch 😦
Because of this, I decided to setup a new application – Dancing QT. It uses alsaplayer because of its excellent interface and pitching capabilities, it uses an embedded SQLite DBMS to maintain a song database, and it uses taglib to populate the database. The interface is written in C++ using Qt. Because of the alsaplayer dependency, the target platforms will be limited to environments providing alsaplayer.
