Changing Sound Track Volume Levels and Other Audio Settings
You can change the volume and balance of audio and music tracks. For example, if a movie has more than one audio track, you can adjust the volume of the tracks relative to one another. You can also change the bass and treble levels.
To change settings for an audio track:
- In QuickTime Player, choose Window > Show Movie Properties.
- In the Properties window, select the audio track and click Audio Settings.
- Drag the sliders to adjust the settings.
- Use the pop-up menu to the right of each audio channel to specify where the channel's sound should be directed.
To direct a channel's sound to the subwoofer, choose LFE Screen. To specify a particular output for the audio device, choose one of the Discrete options. To silence a channel, choose Unused.
- To turn off the audio (without having to delete the track), select Mute. To play only the selected audio track, select Solo.
- To save the balance and channel settings with your movie, choose File > Save or SaveĀ As.
