Mixing audio involves adjusting volume levels so that they maintain a good range within each clip, and then adjusting them in proportion to other clips used in the movie. For example, you might first adjust the volume of a narration clip so that there is little variance between its softest and loudest sections; then raise the narration’s overall volume so that it is clearly audible over background sounds or music included in other clips.
In Premiere Elements, volume changes are measured in decibels. A level of 0.0 dB is the original volume (not silence). Changing the level to a negative number reduces the volume, and changing the level to a positive number increases the volume.
To control a clip’s volume, you can use the Volume graph—the yellow line running horizontally across the audio track of each clip (sometimes referred to as the volume rubberband)—or the Audio Mixer. You can use the Audio Meters window to view the overall audio volume for your project.
Consider the following guidelines when adjusting volume levels:
