opus replaygain vs other replaygain loudness #12

Closed averms closed 5 years ago

averms commented 5 years ago

If I run this on my library that is partly opus and partly m4a, it seems like it will tag the files with different base loudnesses. This is bad if I want to skip from an opus track to an m4a track. If this true can we get an option that makes the entire library have the same loudness?

The different tag formats (ReplayGain and Opus R128_GAIN) use a different reference loudness level. This is properly handled by storing the track loudness relative to that reference, and allows having a similar level across different formats (exactly what you want).

Try it yourself with a player that supports both gain formats (ie. for Android Foobar2000 or GoneMAD Music Player), and you will see hear that it works.

Oh okay that make sense.
