Virtual Audio Cable is a Windows multimedia driver allowing you to transfer audio (wave) streams from one application to another. It creates a pair of Wave In/ Out devices for each cable. Any application can send audio stream to Out device, and any other application can receive this stream from In device. All transfers are made digitally, providing NO sound quality loss. VAC is a "wave-version" of the "MIDI loopback cable" like MultiMid or Hubi's Loopback drivers.

Virtual Audio Cable is a software that allows you transfer wave streams.

If more than one applications are sending audio to VAC, it will mix all streams together. If more than one applications are receiving audio from VAC, it will share the same audio data between all targets.

VAC is useful to record application's audio output in real time (for example - Generator, Reality or other software synth), or transfer a sound stream to another application processing it. You can, for example, use two or more software audio generators/synthesizers/sequencors to produce audio streams sending them to VAC Out, and record the mixed stream from VAC In using any recording software - Windows Sound Recorder, Sound Forge, WaveLab, Cool Edit, Gold Wave, Cakewalk, Cubase etc.

You can use VAC to "thief" an output sound stream from the application that doesn't allow to write it into WAV file directly. Unlike Total Recorder allowing you to simply save audio stream, VAC allows to route it in real time.

Here are some key features of "Virtual Audio Cable":

· Up to 64 cables.
· 1..100 milliseconds per interrupt.
· Almost no sound latency with maximal interrupt frequency.
· Almost any of PCM sound formats (sample rate, size and number of channels). Number of bits per sample is limited to 32, and number of channels is limited to 256.
· Unlimited number of clients connected to each port.
· Sound mixing (with saturation) between output port clients.
· Synchronous mode transfer support to achieve maximal reliability.
· Control Panel application to dynamically configure cables.
· Audio Repeater application that transfers from any Wave In to any Wave Out port


Requirements:

· Any hardware configuration (CPU, RAM etc.) enough for supported operating system.


Limitations:

· The trial version is feature limited
