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.
Look into audio normalisation… for playback purposes scanning/applying Replay Gain on the files should help a bit. Most audio playback software has support for that.
There is also EBU R 128, a slightly different type of loudness normalisation, it uses a different algorithm vs traditional Replay Gain. For my own usage I found it works better keeping the loudness at the same level when playing through a bunch of different audio tracks. No idea about VLC but the Strawberry application does support it so it could be worth a look if you want to try other audio playback software.
