I teach podcast courses on Audacity and a question that comes up frequently has to do with the difference between loudness (LUFS) and volume. It can be a challenge to wrap our brains around, but there is a difference.

The bottom line is that loudness is digitally embedded in the waveform as part of our editing. When I level a piece of audio to a LUFS level, I'm manipulating the waveform to adjust it to a consistent loudness end-to-end, eliminating extreme peaks and valleys in the loudness and creating a more consistent listening experience. This reduces or eliminates the need for the listener to chase the volume up or down while listening because the loudness has been leveled. The listener can't adjust the loudness because they can't get to the waveform to manipulate it. But you and I can as editors. Let's talk...
