virtual audio cable setup for dual output

If you use an audio encoder application that encodes a stream coming from a sound card, you can use VAC to supply such encoder with a stream produced by other application.

With an ASIO wrapper like ASIO4ALL from Michael Tippach, you can use VAC in ASIO supporting applications. You can, for example, use two or more software audio players/generators/synthesizers/sequencers to 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 (formerly Cool Edit Pro), Gold Wave, Cakewalk/Sonar, Cubase/Nuendo etc. VAC is useful to record application’s audio output in real time (audio player, instant messenger or software synthesizer), or transfer a sound stream to another application processing it. If more than one applications are receiving audio from Virtual Cable device, VAC distributes the same audio data among all targets. If more than one applications are sending audio to Virtual Cable device, VAC mixes all streams together. If you simply need a function like “Stereo Mix” under Vista/Win7/Win8, there could be better to try to enable it in your audio adapter. VAC behavior is similar to “What You Hear” (or “What U Hear”, “Stereo Mix”) feature of Sound Blaster Live! and Audigy cards. All transfers are made digitally, providing NO sound quality loss (a bitperfect streaming). Any application can send audio stream to an output side of a cable, and any other application can receive this stream from an input side. It creates a set of virtual audio devices named “Virtual Cables”, each of them consists of a pair of the waveform input/output devices.

Virtual Audio Cable software allows you to transfer audio (wave) streams between applications and/or devices. Virtual Audio Cable v4.67 WiN P2P | 17 July 2022 | 1.8 MB
