    All audio work is in the Audio tab of the inspector. The tab has two parts: Mix and Add.

    Mix

    SectionWhat it does
    Volume (this clip)Sets the volume of the selected clip.
    TracksLists each audio track, such as Microphone, System Audio, Voiceover and Background Music. Each track has a Volume control, Mute and Solo.
    DuckingLowers other audio while you speak. See Background Music.
    Listen to MixPlays the audio mix so you can check it.
    LoudnessSets the loudness Target for audio enhancement.

    Open the menu of a track for more options, such as Audio Channels (Stereo, Mono (Center), Use Left Channel, Use Right Channel) and Show on timeline.

    Remove Background Noise

    Audio enhancement shows under the microphone track in Tracks. It runs on your Mac. It removes keyboard clicks, fans and room hum.

    1. Click the Audio tab, then Mix.
    2. Under the microphone track, turn on Audio enhancement.
    3. If the v9 engine is available, choose Noise Reduction or Studio.
    4. Set Strength. A strong setting can make the voice sound thin.

    ScreenKite keeps the original audio, so you can turn enhancement off again.

    Remove background noise

    Default engine

    Choose the default engine in Settings → Audio → Audio enhancement:

    • Always v9 (Noise Reduction) (default)
    • Always v8 (Screen Studio Voice)
    • Always v7 (Studio Voice)

    A choice that you make on a clip in the inspector takes priority over this setting.

    💡

    v9 needs Apple Silicon. See System Requirements.

    You can record your voice after the screen recording is done.

    2. Click the Audio tab, then Add.
    3. In Voiceover, choose a Microphone.
    4. Click Record voiceover from playhead.
    5. Speak. Click Stop recording when you are done, or Cancel to discard it.

    The voiceover goes on its own track. You can also right-click a timeline lane and choose Record Voiceover.
