ShanDj

Probably the most portable DJing software solution ever. Convert your audio both into mp3 and ogg, put it on a USB key with the ShanDJ.html file, and go DJ on any machine with a web browser newer than 2008.

Please both read this and refer to the project wiki for complete information.

This is not meant to be used over the internet. You'll have to download it, place the ShanDj.html file in the directory where the audio files are, then open it in your web browser. Audio formats supported are varying depending on the browser. HTML5 browser support and Javascript required (browsers newer than 2008). Features simple playlists and a crossfader to mix between two currently played tracks, and a RobotDJ mode.

If you are looking for a similar tool, but for use over internet instead of locally, you should take a look at Slcnc CMS, from the same developer, which integrates DJing over internet among other features.
