Noise Removal in Camtasia is designed to remove subtle background noises from the recorded audio. This will work best with consistent background sounds, however it will not work well to remove transient sounds.
Some examples where noise removal will work best include:
Some examples where noise removal will not work well include:
- A door closing
To start, drag the Noise Removal audio effect to the audio on the timeline to see if it removes the noise.
If this does not work, use the Analyze button to make a noise print of the noise you are trying to remove. The noise print helps Camtasia identify the exact noise that you are trying to remove, and then attempts to remove it from the rest of the audio.
- Drag the Noise Removal effect to the audio on the timeline.
- Locate a section of audio that only contains the noise you are trying to remove.
- Use the red and green markers of the playhead to select that region with just the noise.
- Click the Analyze button.
There are two sliders in the Noise Removal properties. Adjusting these sliders will allow you to fine tune the noise removal effect. However, adjusting these sliders too much in one direction or the other may cause the rest of the audio (the audio that is not noise - for example your voice) to sound distorted.
The Sensitivity slider will adjust how often the noise removal effect will be applied throughout the audio, based on how loud the noise is. When the sensitivity is low, the noise removal will not apply unless the noise is very loud. When the sensitivity is high, the noise removal will apply even if the noise is very soft. So, if the good audio starts to sound distorted, lower the sensitivity.
The Amount slider will determine how much noise reduction is applied when a noise is detected. When the amount is low, the less dramatic the noise removal will be. When the amount is set to high, the more dramatic the noise removal will be. If the good audio starts to sound distorted, lower the amount.
