How do you adjust the volume of a sound in Adobe After Effects?

To adjust the volume of a sound in Adobe After Effects, changing the dB value for the audio levels in the timeline panel is a fundamental approach. The timeline panel allows for direct manipulation of audio keyframes and levels, where the decibel (dB) scale is commonly used for audio adjustments. By changing the dB value, you can increase or decrease the audio volume precisely within your composition.

This method is efficient because it not only lets you set static levels but also allows you to keyframe volume changes over time, enhancing your ability to create dynamic audio environments in your projects. Other options, while they may lead to volume adjustments, are either specific scenarios that may not always be necessary or do not offer the same level of control and ease as manipulating the dB value in the timeline.
