Below is all the infomation you'll need to fully configure Noise Blocker.

Select Input Device

Noise Blocker needs to know which microphone to use.
Check the selected Input Device and change accordingly.

Add Noises

To filter out noises, Noise Blocker needs you to record a sample of the noise. Click on Add and follow the instruction to record and label a noise.

Tips:

For best results, it's often useful to start out by recording just the microphone's background noise.

Record isolated noises one at a time, e.g. one for keyboard noise, one for mouse clicks, etc.

Configure Settings

You can fine-tune Noise Blocker to work for your setup and environment.
There are 3 main options:

Threshold

When the filtered audio's volume level goes above this, Noise Blocker will allow audio through.

Tip:

It's not unusual for this to be set to 0.

Noise Reduction

Control's the amount of supression applied to the unfiltered incoming audio.
The higher this is set, the greater the amount of noise reduction applied.

Tips:

If you find your voice is being cut out, try lowering this setting gradually.

If you find noises are still coming through, try increasing this setting gradually.

Release Delay

How long (in milliseconds) the microphone should stay on after the volume has dropped below the threshold.

Configure other applications

Finally, you'll need to configure any application to use Noise Blocker's virtual microphone.
The virtual microphone is the filtered audio.
Typically this mean's selecting "Microphone (Noise Blocker Virtual Audio Device (Wave Extensible) (WDM))" in your application (Skype, Discord, Google Hangout, etc) of choice.

Unlock Noise Blocker

In trial mode, Noise Blocker is limited to a daily usage of 1 hour.
If you would like to remove this restriction, please consider purchasing a life-time single user license.

Purchases greatly aid the development and maintenance of the application.
