Using audio layers

In After Effects, you can change volume levels of audio layers, preview them at a specified quality, and identify and mark locations. An audio layer contains different properties than a video layer, but you modify them the same way. You can apply special audio effects to audio layers, and adjust the waveform values. (See Adding markers synchronized to audio.)
