Hello,
what I mean by that is that whenever I download a song from youtube using yt-dlp and listen to it using mpv it always feels like I am listening to a higher quality version of the music, I don’t know it it’s just me or there is some scientific reason behind it.


Volume and Dynamic Range are different things. One doesn’t effect the other.
Stable Volume just uses a form of ReplayGain to adjust volume for each track so they don’t swing so much.
It’s not doing any dynamic range compression, like some Nighttime Listening mode.
