Dragging to preview composition audio
You can preview audio by dragging the time marker. in a composition. Use this technique
to easily identify and mark a location to synchronize audio and visual effects. Instead of
using the audio waveform, you can identify a location in the layer by moving the current-
time marker in the Timeline window and listening to audio playback.
To preview composition audio:
In the Timeline window, press Ctrl (Windows) or Command (Mac OS) while you move
the current-time marker.
As you drag across time, After Effects plays segments of the audio. You can play the audio
forward or backward. If you stop moving the current-time marker while keeping the
mouse button depressed, a short section of audio will loop.
Changing volume levels of an audio layer
When you use footage containing audio, the audio level in the footage plays at 0 db,
meaning that the level is unadjusted in After Effects. Setting a positive decibel level
increases volume, and setting a negative decibel level decreases volume.
