As someone who downloads or buys their music to listen to via VLC, it’s quite annoying when the volume level between files aren’t consistent. Especially when I’m unable to easily to change the volume like when I’m doing physical labor as an example. So it can go from a perfectly reasonable volume, to damaging my ears, and then to where I can barely hear. I was thinking of going in and manually editing them myself to be consistent amongst each other at some point, but then it got me thinking. Is there an application that will equalize the volume on your audio files for you? If not, would anyone else have a use for one besides me? I’d love to know either way.
The process you’re looking for is called loudness normalization. You want to batch normalize your audio files to a set LUFS value(probably around - 14LUFS). I think there is a way to do this in batch proccessing with audacity.
