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).
