GDAM is "Geoff and Dave's Audio Mixer"
GDAM is a digital dj mixing software package. It aims to be a powerful, professional-quality music mixing and remixing system, suitable for live performance. It was conceived on some beautiful summer morning (in 1998), and developed with drive and enthusiasm that seemed completely unnatural. Nearly two years later, we have achieved many of our goals; yet, development remains as hectic. Here is a list of features:
client-server architecture based around glib
streaming and mixing of any number of mp3 files
dynamic filter insertion and removal
multiple sound device support
plugin support
cacheing / playing loops
contiguous queueing - plays albums without gaps between songs, regardless of output buffer size
dj turntable-style interface
assisted beat matching
waveform viewer / beat calculator
sequencer
record from any point in the stream, to disk or another process
gtk gui's, with simple skin support
flexible command-line interface
gdam123 - an mpg123 clone that talks to a gdam server
hardware input support (midi and other)
support to use LADSPA plugins
