Virtual Audio Cable 3

Virtual Audio Cable 3 is a previous version of VAC, implemented as a Windows MME multimedia audio driver. Major differences are the following:

Feature VAC 3 VAC 4
Audio interface MME WDM
Platforms Windows 98/ME, 2000/XP/2003 Windows XP/2003/Vista/Win7/8/8.1/10
64-bit OS support No Yes
DirectSound in Win2000/XP/2003 Emulated Native
Format conversion No Yes
Volume control No Yes
Channel remapping No Yes

In systems supporting both VAC 3 and VAC 4, old version can be better than the new if applications on both sides use the MME (waveIn/waveOut) audio interface, and can be configured to use a single, common audio format. If at least one application uses DirectSound interface and/or different audio format, VAC 4 is preferred.

In any case, you always can download a free trial and test both versions. VAC 3 and VAC 4 can coexist in the same system if you choose different installation directories and Start Menu groups. But different versions of VAC 3 or VAC 4 (for example, 3.10 and 3.12 or 4.01 and 4.02) cannot coexist in the same system.

Features

  • Windows 98/ME and Windows 2000/XP/2003 platforms.
  • Windows MME (waveIn/waveOut) audio interface. DirectSound interface is directly supported under Windows 98/ME but emulated under Windows 2000/XP/2003.
  • Up to 256 virtual cables.
  • 1..20 milliseconds per interrupt.
  • Almost any of fixed point PCM audio formats (200..1000000 samples per second, 8..32 bits per sample, 1..8 channels). Floating point formats are not supported.
  • Almost no sound latency with maximal interrupt frequency.
  • Unlimited number of clients connected to each port.
  • Signal mixing (with saturation) between output port clients.
  • Control Panel application to dynamically configure cables.
  • Audio Repeater application that transfers from any Wave In to any Wave Out port.
