Virtual Audio Cable software allows you to transfer audio (wave) streams between applications and/or devices.f / ` l u It creates a set of virtual audio devices named “Virtual Cables”, each of them consists of a pair of the waveformN z – f & 0 { s v input/output devices. Any application can send audio stream to an output side of a cable, and any other aX S l cpplication can receive this stream from an input side. All transfers are made dig7 v Pitally, providing NO sound quality loss (a bitperfect streaming).

VAC behavior is similar tb B q / do “What You Hear” (or “What U Hear”, “Ste) j :reo Mix”) feature of Sound Blaster Live! and AudigO Y + ! 7 ;y cards. But it is od A _ E ~ ~nly similar, n5 J y %ot equivalent. If you simply need a funcL , c C % }tion like “Stereo Mix” under Vista/Win7/Win8, th{ G ] R M R aeri 7 Z = a E _ se could be better to try to enable it in your audi9 Y Oo adapter.

If morp ; f L t G v [e than one applications are sending audio to Virtual Cable device, VAC mixes all streams together. If more than one application3 ( r n } : w I Ss are receiving audio from Virtual Cable device, VAC distributes the same audio data among all targets.

VAC is useful to record apK I r ] e mplication’s audi& A P a G e 3o output in real time (audio player, instant messenger or software synthesizer), or transfer a sound stream to another application processing it. You can, for example, use two or mor– u # H F te software audio players/generators/synthesizerm z , }s/s$ C G ~equencers tz . = P 4 ao produce audio streams, sending them to Virtual Cablet device and record a mixed stream from the same Virtual Cable device, using any recording software – Windows Sound Recorder, Audacity, Sound Forge, WaveLab, Adobe Audition (foq Y q 2 y g 6 ( @rmerlyX v U CoolM _ B f [ Edit Pro), Gold Wave, Cakewalk/Sonar, Cubase/Nuendo etc.

With an ASIO wrapper like ASIO4ALL from Michael Tippach, you can use VAC in ASIO supporting aD M . 5 \ppl4 | Oications.

VAC needs no hardware audio card; it is a “virtual audio card” itself.
