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 is new in this release:
Version 4.62: Fixed Audio Repeater bug that caused hangup on device disconnection. Added top speaker channel support. Added signal processing mode support. Replaced independent cable clock sources with a single kernel timer to allow multiple cables to be coherent. Fixed a bug in calculation of minimal cable event period (Cable Info window). Fixed a bug in WaveRT capture stream processing that caused data loss on short buffering time. Increased cable clock calculation precision, eliminating error accumulation. Increased clock register bitness up to 64 and precision up to QPC resolution. Added workaround for audio device properties confusion due to permanent property caching in Win10. Cumulative algorithm for actual sampling rate calculation. Added Sound Settings and Microphone Privacy buttons to the Control Panel. Added Microphone Privacy reminders to Audio Repeater and Control Panel. Changed signal level indicators from linear to logarithmic for better visibility. Added gauge coloring to Audio Repeater windows. Added automatic uninstaller launching feature to the setup application. Added default endpoint checking feature to the setup application. In the setup application, using more reliable device uninstallation algorithm. Clarified names of System Audio Engine and Audio Service. Added feature-limited free version. Removed three-cable limitation from trial version.
What is new in version 4.60:
- Added RT Audio packet streaming support.
- Increased maximum number of supported channels to 32 (may cause problems, consult the manual).
- Decreased default timer event period down to 3 ms to avoid RT Audio (WaveRT) glitches.
- Show actual and potential cable/stream problems with state icons.
- Show circular buffer duration and amount of buffered data (in milliseconds) in stream lists.
- Show stream processing modes in stream lists.
- Made application windows DPI aware (no blurring on high DPI displays).
- Added high-resolution icons.
- Added tooltips to application controls.
- Added "Help" button to Audio Repeater applications.
- Added a private property set accessible via any KS interface.
- Added registry parameter for timer resolution adjustment.
- Increased trial voice reminder delay to 30 minutes.
- Added voice reminder status (silent/audible) indication to Control Panel.
- Removed stream data buffer and stream watermark support because they were hard to tune and not very efficient against stream stability problems.
- Some changes in Conrol API, not binary compatible with previous versions.
- Fixed bug causing BSOD on some rare formats and settings combinations.
- Fixed buffer notification positions.
- Fixed minor bugs.
What is new in version 4.51:
- Added second INF file to install under Win 6.x (Vista, Win 7/8/8.1).
- Changed class/interface GUIDs for the driver, Control API and Native Mode key (custom versions only).
- Decreased noise level in Native Mode.
- Uninstall entry is now created with a constant product GUID.
- Minor bugfixes.
What is new in version 4.50:
- Fixed a bug caused Control Panel crash if VAC driver cannot be restarted.
- Split monolithic cable KS filter into two separate render/capture filters.
- Added WaveRT (RTAudio) and WaveCyclic port/miniport interface support.
- Removed 16-cable limitation from the default INF file.
- Met Device Guard requirements.
- Signed with EV certificate to allow loading by Win10 in Secure Boot mode.
- Added load/save configuration features to Audio Repeater.
- Added actual sampling rate display to Audio Repeater.
- Added stream's actual sampling rate and run time display to VAC Control Panel.
- API: replaced CreationTime field in CableInfo with LifeTime to prevent calculation errors.
What is new in version 4.15:
- Added KSEVENT_PINCAPS_FORMATCHANGE event support.
- Replaced source line summer with a multiplexer.
- Added recording side volume control.
- Added cable information window with stream information list.
- Added event log feature.
- Fixed some bugs in KS version of Audio Repeater.
- Added some options and useful information display to KS version of Audio Repeater.
- Added MMCSS task registration to Audio Repeater to control thread priority.
- Fixed a bug in resuming the streaming after sleep/hibernation.
- Added Ctrl-C support in Audio Repeater "Wave in" and "Wave out" fields to copy device name to the clipboard.
- Increased small buffer movement uniformity between VAC driver and applications.
What is new in version 4.14:
- Fixed a bug caused playback at higher speed.
- Added a workaround for PortCls bug (GetMaxMapRegisters function) causing position freezing.
- Fixed a bug caused signal level to be painted over the header in Control Panel application.
- Added stream buffer control to minimize overflows/underflows.
- Added button to restart System Audio Engine.
- Now filter volume/mute nodes always report 8-channel support.
Limitations:
2-cable trial
