The Audio Volume node allows you to modify or change the audio volume of an audio clip, including fading in and out as well as audio normalization. This node is intended to be used on your Reference Audio nodes or after extracting the audio from a video. Like most workflow nodes, you may pass in multiple audio files to modify them with a single node. The specific parameters it supports are:
Volume (in dB): The target volume of the audio.
Fade In: The duration (in seconds) to fade in from silence from the start of the audio clip. The default is 0.
Fade Out: The duration (in seconds) to fade out to silence to the end of the audio clip. The default is 0.
Enable Normalization: Allows for the audio clip to use EBU R128 loudness normalization to the clip.
