RELEASED October 14, 2020

Bug fixes

RELEASED June 02, 2020


  • You can now boost or reduce the volume of the virtual microphone through the "Settings" tab.
  • By default, the virtual microphone will no longer allow other applications to adjust its volume. Previously other applications with "automatic gain control" could sometimes (incorrectly) boost the system level volume of the virtual microphone causing loud, distorted audio. This setting can be disabled if required.
  • Now if the application is re-launched, but is already running, the running application will be brought to the front and shown instead of displaying an error message.

Other changes

  • When uninstalling the application, you can now optionally toggle if you want settings/recorded noises to be removed.

Bug fixes

  • If the application unexpectedly crashes, it should correctly close all running processes. This could previously prevent the application from restarting after a crash.

RELEASED March 04, 2020

Major release

In this release, we have completely reworked the virtual microphone. The new and improved drivers should have lower audio delay and improved stability with prolonged use.

Other improvements

  • Low power mode. When the app is minimized, it will now only process audio when the virtual microphone is in use. This should result in less CPU usage and works better with Bluetooth headsets.
  • Smaller package size. Through some code clean up, we've managed to shrink the size of the application from 68 MB to 36 MB.

Changes and deprecations

Easier configuration!

  • The ability to select which audio system to use is no more. The "Experimental" audio system introduced in 1.2.0 is now used by default.
  • With the new drivers, you no longer have to select which "Output Device" to use, as such this option has been removed.

RELEASED July 17, 2019

Major release

In this upcoming release, we are rolling out a brand new audio system that should help reduce the latency of the virtual audio routing.

To enable it, first navigate to the "Settings" tab then under "Audio System" select "Experimental" from the drop down.

After a quick restart, Noise Blocker will boot with the new audio system enabled.

The previous audio system is still available and used by default. If you encounter any issues, you can switch back at anytime.
Once we are happy that the new audio system is fully stable (any bugs/issues discovered are resolved) in the next major version released it will become the default. However, we still plan to keep the legacy audio system around as a fallback option.

If you encounter any issues or bugs with the new audio system, reporting them to would be greatly appreciated.

Other improvements

  • Device disconnect warning dialogs can now be disabled.
  • When minimized to the system tray for the first time, Noise Blocker will let you know it's still running in the background.
  • You can no longer select the virtual speakers as your systems default playback device.

Bug fixes

  • Fixed an issue where the virtual audio devices would not be correctly configured on install in rare cases (causing deep voice/static noise).
