Welcome to the Audacity Bootcamp Podcast. I teach podcast courses on Audacity and a question that comes up frequently has to do with the difference beween 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…
In the last video I talked briefly about the difference between loudness and the amplify effect in Audacity. Let’s put another piece of the puzzle together by talking about the difference between loudness and volume. I talked about this in a previous video but the question comes up a lot so I want to address it again, emphasizing that loudness is a component of the waveform. These are not the same thing. Loudness is embedded in the waveform and volume is not. Let’s talk about it.
If you do Loudness Leveling on your podcast (and I hope you do), is that the same as volume level? Are loudness and volume the same thing? That’s the topic for this video as we look at the difference between loudness and volume when it comes to leveling our audio to a LUFS standard.
