VAC is a native 32- and 64-bit WDM PnP driver and works under Windows XP / 2k3 / Vista / Win7 / 8/8.1 / 10. Use it to create a chains of software synthesizers (Generator, Reality), audio processors, recorders (Audacity, WaveLab, Sound Forge, Adobe Audition), sequencers (Cakewalk, Sonar, Logic, Cubase, Nuendo), Internet Telephony / Voice applications (Skype) etc. VAC operates like TotalRecorder but is more universal. Thus, you can record and process output of almost any audio application by almost any other audio application. So, I was using a total of four audio cables: VAC 4 - Audio Input from Skype to vMix (selected as the 'speaker' in Skype and added as an audio input in vMix). 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. The other night, I tried using two pairs of Virtual Audio Cables to run audio to and from vMix with Zoom, and to and from vMix with Skype, all on the same laptop. VAC is intended to connect several audio applications together in real time. Virtual Audio Cable Screenshot Version: 4.50
