Adjust Loudness (vuo.audio.loudness)

Changes the volume of the audio channels.

This node uses a rough approximation of perceived loudness, so that doubling the Loudness input value will make the audio sound twice as loud.

• Loudness — The volume of the output relative to the input. At 1, the volume is unchanged. At 2, the volume is doubled. At 0, the volume is silent.
