Developer's Description

Virtual Audio Cable connects audio applications together in real time. 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. Thus, you can record and process output of almost any audio application by almost any other audio application.

What's new in version 4.70

  • Added ARM64 binaries.
  • Fixed a driver bug that caused render streams to speed up when volume control and/or format conversion are used.
  • Fixed a driver bug that caused OF/UF values in the stream termination event to always be zero.
  • Added client clock adjustment feature to the driver, allowing applications to adjust cable clock on the fly, without changing cable clock correction value permanently.
  • Packet mode support is disabled by default to improve stream reliability in typical applications. Packet mode controls added to VAC Control Panel.
  • Added a workaround for Windows bug that requires to start high-level clients before KS ones.
  • Added the name of the process that created the stream to the stream information.
  • Changed algorithm of actual sampling rate calculation for better reflection of recent changes.
  • Added a dynamic cable clock adjustment to Audio Repeater applications.
  • Changed layout of Audio Repeater KS window to fit low-height screens.
  • Audio Repeater MME now finds the endpoint by name when the transfer is started. It allows to avoid restarting the app if endpoint order was changed (when audio devices are plugged/unplugged, default endpoint is changed, etc.).
  • Added workaround to Setup application to remove hidden "phantom" device instance if the previous installation was forcibly aborted.
  • Setup application now searches for uninstallers of older versions.
  • VAC driver API version increased to 6.
