The audio waveform allows users to visualise the audio output of a single layer, a collection of layers or the quantized audio track while working in the keyframe editor. This permits them to add keyframes while taking audio output as a consideration at a glance.

To visualize the audio waveform of one or more layers:
Create one or more audio layers.
Set the audio track of the layer(s).
