    • Push to Talk keeps the microphone muted except while the shortcut is held.
    • Push to Mute keeps the microphone active except while the shortcut is held.
    • Assign a keyboard combination or auxiliary mouse button, optionally combined with Ctrl, Shift, or Alt.
    • Configure a release delay for Push to Talk to keep the microphone active briefly after releasing the shortcut.
    • Play optional audio cues when the shortcut mutes or activates the microphone.
    • Use the shortcut exclusively to prevent other applications from receiving the same input.

    • Automatically strip leading and trailing whitespace when entering license details.

  6. 3.0.0

    Noise Blocker 3.0 is a complete ground-up rebuild of the desktop app and audio engine, introducing AI-powered audio processing and a redesigned experience.

    New

    • AI-powered noise cancellation that works out of the box.
    • AI-powered voice gate with adjustable sensitivity and release timing.

    Download 3.0.0

  7. 2.0.6

    Fixed

    • Fixed an issue where removing a noise after recording a new noise.
    • Noises will now remain unchecked after the app reboots.
    • Fixed a license activation issue that was affecting a small subset of users.

    Download 2.0.6

  8. 2.0.5

    Improved

    • 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 apps with “automatic gain control” could incorrectly boost the system volume, causing loud, distorted audio. This setting can be disabled if required.
    • Re-launching the app while it's already running now brings the running window to the front instead of showing an error.

    Changed

    • When uninstalling, you can now optionally toggle whether settings and recorded noises are removed.

    Fixed

    • If the application unexpectedly crashes, it now correctly closes all running processes — this could previously prevent a restart after a crash.
    Download 2.0.5

  9. 2.0.4

    Fixed

    • Fixed an issue where the app would sometimes not correctly resume after the PC woke from being locked or slept.
    Download 2.0.4

  10. 2.0.3

    Improved

    • You can now see whether the virtual microphone is in use under the Settings tab.

    Fixed

    • Fixed an issue introduced in 2.0.2 that could crash the audio stream when switching input devices.
    Download 2.0.3

  11. 2.0.2

    New

    • Added the ability to report issues in-app — submit a report via the ‘Report Issue’ button under the ‘Settings’ tab.

    Fixed

    • Fixed an issue with the virtual drivers when used by kernel-streaming apps (like GeForce ShadowPlay) that could cause audio glitches at certain sample rates.
    • Fixed an issue where noises could not be recorded when the user's username contained non-ASCII characters.
    • Fixed an issue where the app could freeze when deselecting a noise.
    Download 2.0.2

  12. 2.0.1

    Fixed

    • Fixed an issue where the new drivers would fail to load on certain machines.
    Download 2.0.1

  13. 2.0.0

    We've completely reworked the virtual microphone. The new and improved drivers should have lower audio delay and improved stability with prolonged use.

    Improved

    • Low power mode — when minimized, the app now only processes audio while the virtual microphone is in use. Lower CPU usage, and it works better with Bluetooth headsets.
    • Smaller package size — some code clean-up shrank the application from 68 MB to 36 MB.

    Changed

    • The option to select which audio system to use is gone. The “Experimental” audio system introduced in 1.2.0 is now used by default.
    • With the new drivers you no longer have to select an “Output Device”, so that option has been removed.
    Download 2.0.0

  14. 1.2.9

    Fixed

    • Fixed an issue where newly added noises might not save between app reloads.
    Download 1.2.9

  15. 1.2.8

    Changed

    • A small percentage of new users will be opted in to the new Experimental audio system by default.

    Fixed

    • Fixed an issue where audio would play out via the default playback device before the virtual drivers were installed.
    • Added extra checks to prevent settings from getting corrupted.
    • Fixed an issue with the in-app update notification.
    Download 1.2.8

  16. 1.2.7

    Fixed

    • Fixed an issue with the latest Windows update and the ‘Experimental’ audio system where the virtual microphone audio could become delayed after extended use.
    • Fixed a rare issue with the ‘Experimental’ audio system which prevented new noises being recorded.
    Download 1.2.7

  17. 1.2.6

    Fixed

    • Fixed an issue that prevented ‘Start on boot’ from being disabled (once enabled) on certain machines.
    Download 1.2.6

  18. 1.2.5

    Fixed

    • Fixed an issue where the virtual drivers could be incorrectly configured on install, resulting in excessively loud audio.
    Download 1.2.5

  19. 1.2.4

    Improved

    • On launch, the app now ensures the volume of the virtual drivers is set correctly.
    • Improved the robustness of the ‘Experimental’ audio system against lag spikes from the input device.
    Download 1.2.4

  20. 1.2.3

    Improved

    • Optimized the performance of the ‘Experimental’ audio system to use less CPU.
    • Improved how the ‘Standard’ and ‘Experimental’ audio systems perform when the CPU is under heavy strain.

    Fixed

    • Fixed an issue where the ‘Experimental’ audio system could start ‘stuttering’ after extended use.
    Download 1.2.3

  21. 1.2.2

    Fixed

    • Fixed an issue that stopped the application launching on boot.

    Changed

    • Reduced the total size of the installer.
    Download 1.2.2

  22. 1.2.1

    Fixed

    • Fixed a memory leak that could occur when activating ‘Listen To Input Device’ with the ‘Experimental’ audio system.
    • Improved handling of the ‘Experimental’ audio stream when the entire system is under heavy CPU usage.

    Changed

    • Made improvements to the application's internal logging and error tracking system.
    Download 1.2.1

  23. 1.2.0

    We're rolling out a brand new audio system that should help reduce the latency of the virtual audio routing. To enable it, open 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 hit any issues you can switch back at any time.

    Improved

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

    Fixed

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