Points to Consider Before Using Audio Enhancements

Audio Enhancements affect the entire audio timeline, not just specific clips you may select.  Therefore, it is best to wait until you have all of the Timeline editing completed before applying the Audio Enhancements.
When the Even out volume levels option is "on", immediate improvement in the variation of the waveform sound levels occur.

When the Noise Reduction option is "on", the color of the audio waveform will change from teal to burgundy.  This makes it easy to see when audio enhancements have been enabled.

How to Even Out Volume Levels (Dynamic Range Control)

If you have audio recordings from multiple people or from multiple sources such as an individual in the room and one on the phone you know how difficult it can be to match the audio levels. Camtasia Studio allows you to  equalize the volume level, which results in more consistency in your audio.

With your audio on the Timeline, click  Audio Enhancements in the Task List:

• Click the Even out volume levels check box.

• Choose the Volume variation that best suits your audio. You should try the different settings to see how the audio level changes. There are four settings available:
• High Volume Variation
• Medium Volume Variation
• Low Volume Variation
• Custom Settings

 

How to Remove Background Noise

Unless you are recording in a recording studio or an area developed specifically for recording, it can be difficult to record good audio. The environment you record in and the microphone used can have a large effect on the quality of the recording. There are noises in our everyday environment that can and do affect audio recording, such as air vents, fans and other background noise.

How to Automatically Remove Background Noise

To remove background noise there are two options. The two options are to let Camtasia Studio automatically remove the background noise, or to manually select the background noise for Camtasia Studio to remove. To automatically remove background noise:

• Select Automatically try to detect noise on the timeline and click Remove Noise and listen to your audio to hear the difference.

Note: The wave form on the Timeline should have turned burgundy when Remove Noise is applied.

How to Manually Remove Background Noise

You may also choose to manually remove noise.

• Select  Manually select a region of audio with noise but no voice narration.

• Select a small section of the Timeline with noise to remove, but no narration (if possible).

Note: Select only a small amount of time on the Timeline is required to be selected (no more than 1 second – any more than that is overkill…)

• After selecting a section of noise, click the Remove Noise button.

Listen to the change to the audio.  If the noise removal was not satisfactory, there are two options that may help to achieve the desired results.

First Option

Try switching to Automatically try to detect noise on the timeline and adjust the sensitivity slide bar to be more or less sensitive. Then click  Remove Noise.
 

Second Option

You can click on the Restore noise check box, and reselect a section of the audio Timeline that is a good sample of the noise (again without voice narration if possible). Then click Remove Noise to reset and reestablish the noise removal tool.
