AudioCodex is the real time effects media player for Mac OS X that tightly integrates your media, iTunes Library, Quartz Compositions and Core Audio.
AudioCodex enables you to easily create loops and apply real-time Audio Units effects to tracks from iTunes and elsewhere. It is built around a unique hybrid Core Audio/QuickTime playback engine which preferentially plays files with Core Audio.
AudioCodex features an advanced Quartz Visualizer module for viewing and tweaking Quartz Composer .qtz visualisations. Now you have the perfect player for audio-active compositions.
