13.2 eMixer
eMixer is an easy-to-use front-end to mpg123 that allows you to play and mix two mp3 streams together. The ability to mix two mp3s makes eMixer act like a cross-fader, effectively giving the user DJ-like capabilities from the computer console. eMixer is also very able in a "real time" party environment. eMixer is based on the original mp3 mixing code upon which liveice's mixing component is built.

13.3 GDAM
GDAM is real-time digital dj mixing software package. Any number of mp3 files can be played and mixed simultaneously. Effects can be added, changed, and rearranged dynamically. GDAM features a client-server architecture; all sound is produced by a server, which receives instructions from any number of clients. Other features include plugins for audio effects and interface components, caching and looping, sequencing, assisted beatmatching, a waveform viewer/beat calculator, contiguous queuing (no pauses between songs when using a playlist), an online help system, an mpg123 clone which runs on a gdam server, flexible command line interface for direct control of server, recording of entire mix or any point in stream to buffer/disk/mp3 encoder, support for multiple sound devices, and support for midi hardware control.
