Which audio engineering term refers to the frequency or pitch used to adjust playback equipment volume?

The term that best refers to the frequency or pitch used to adjust playback equipment volume is actually related to sound levels. Sound levels are crucial in audio engineering as they relate to the amplitude of the audio signal, which directly impacts how loud or soft a playback sounds.

Tones refer to the specific frequencies produced by the audio signal and do not directly indicate volume control. Equalization is focused on adjusting the balance between frequency components within an audio signal instead of merely controlling the overall volume. Volume curves describe how volume changes over time within a track, but they do not directly indicate a frequency or pitch related to volume control. Understanding sound levels helps audio engineers maintain clarity and consistency in their recordings and mixes.
