Download ActivePresenter 8 to enhance the audio quality by using the Audio Noise Reduction feature. In such a case, you can create a recording made in identical conditions containing silence only, then use a noise sample from that to reduce noise from the target recording. Sometimes, the audio track doesnвЂ™t have any part that contains only background noise and you cannot get the noise sample.Continue picking the next part and reduce the noise until you get the desired result. So, you should get the noise profile for the first part, then reduce the noise for it. For example, after reducing noise for an audio track, there might be several parts that noise is not completely eliminated. If there are many different kinds of noise in different parts of the audio track, you should repeat the process several times.It will be lost in case you close the program or replace it with another noise profile. The noise profile you got will be stored in the application.You must select a minimum of 2048 samples or about 0.05 seconds at a 44100 Hz sample rate. A selection of 2 вЂ“ 4 seconds of only noise is recommended. When getting a noise profile, you shouldnвЂ™t choose a very short range because the app cannot get the noise profile.

Some Tips When Using Audio Noise Reduction: Bear in mind that you donвЂ™t have to get a new noise profile if you think the existing one is good enough. Alternatively, press CTRL+Z on the keyboard. Note: If the Noise Reduction effect doesnвЂ™t work as you expected, click Restore Defaults and try again with different settings.

Click OK to apply the effect to the selected ranges.

Smoothing can make the desired audio less clear, so set the value to 0 if your desired signal is strong and the noise is low.

Frequency smoothing (bands): Spread the noise reduction into the specified number of neighboring bands.

Thus keep this control as low as possible. Greater sensitivity will remove more noise but it can damage the track.

Sensitivity: Control how much of the audio will be considered as noise.

So, keep this control as low as possible. Higher values reduce higher amounts of volume reduction, making the noise quieter but can distort the audio track.

Noise reduction (dB): Control the amount of volume reduction (0 вЂ“ 48 dB) applied to the identified noise.

Click the arrow button on the Audio Noise Reduction button (1), then select Get Noise Profile.

Select the entire track or specify the range that contains only background noise.

In general, the procedure to use the Audio Noise Reduction feature is to get a noise profile, then reduce the noise. Use Audio Noise ReductionДЄctivePresenter lets you reduce noise for the whole audio track or just a part of it. Overall, this is a process of removing noise from an audio track. Therefore, noise reduction can reduce constant background noise like tape hiss, electric fans, or hums. Regardless of the microphone quality, there is a high chance that your recordings will have some background noise. It can help to improve your audio quality in general and recording quality in particular.

So today, letвЂ™s take a closer look at the Audio Noise Reduction feature in ActivePresenter 8.
