VAC is intended to connect several audio applications in real time. It's like a sound card with hardwired input and output: When an application sends an audio stream to a virtual cable, other applications can record this stream from the other cable end. Thus, you can record and process output of almost any audio application by almost any other audio application. VAC operates like Total Recorder but is more universal. Use it to create a chain of software synthesizers (Generator, Reality), audio processors, recorders (WaveLab, Sound Forge), and sequencers (Cakewalk, Cubase). With Win 95/98/Me, DirectSound is supported.

Version 3.06 adds a number of input/output clients display to the Control Panel and fixes bugs.
