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 – 4 seconds of only noise is recommended. When getting a noise profile, you shouldn’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 don’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 doesn’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 – 48 dB) applied to the identified noise.

It can help to improve your audio quality in general and recording quality in particular. So today, let’s take a closer look at the Audio Noise Reduction feature in ActivePresenter 8.
