Re: Does Volume Levelling use album gain or track gain?

When you level the track.. it uses the replay gain values to alter the actual volume of the track.
If you don't level the tracks, it uses the replay gain values to normalize the tracks while playing them if you have level playback volume turned on.
Does that help make sense of it?


In regard to the comments regarding track vs album gain.
I am a STRONG believer in customization and allowing users to choose according to their needs.
However, I'm also a big believer in protecting the users from making decisions that aren't necessarily in their best interest.

Don't crucify me, but I think that the way leveling is applied (using album gain), is the best option - even to the point of foregoing choice.
In a large part, this is because it cannot be undone very easily.

Consider this. If you change the level of the whole album using album gain, it roughly fixes most volume levels - though there will obviously be certain songs that are extremes... but it does do a rough job of it.
If you want to listen to an album, you can, and all the volumes will all be in sync with each other. If you want to listen to individual tracks, you can, and if the leveling is bad for you, you can run Mediamonkey's "level playback volume" feature which can use the track gain values - hence, you would get the exact same result as if you actually leveled it by track.
Of course, if playing on an ipod or other device you can sync with the appropriate settings to transfer the desires gain values across.

On the flipside however, consider this. If you change the level of each individual track to be normalized only relative to itself, you can listen to individual tracks at the your desired volume and you don't have to turn on "level playback volume" at all. However, if you EVER want to listen to an album, you can never get the tracks to sync volumes again and there is no magic "level back to album volume" setting in mediamonkey to do it for you. You are stuck with track volume forever.

So, even if it becomes an option in the future. I would suggest you use the "album" gain values to level your albums as it has the best of both worlds, where as using the "track" gain locks you into that, destroys the relationship between the songs on the album and is irreversible.. for no real advantage.

Album Volume is good when you play Albums and you care to preserve the volume differences between the tracks on the Album. Track Volume is good when you play tracks from different albums. This is why this should be optional as different users will have different needs.

Thanks Lowlander, but neither of the pre analyzed track or album volume will affect normalisation will it?When normalisation is modifying the actual file, not the tag i dont see how the replay gain values could make a difference. It's altering the actual file to a set db level that i understand is set in Options/Volume Leveling/Target Volume For Leveling Tracks (So i always believed anyway). Thanks for your help on this........

well how is it normalising volume then?i thought it just modifies the file's overall volume to the setting in the volume leveling preferences.if i have mine set to 89db (which it is), and normalise a file, the track and album volume should both reflect the change to the normalised volume.??????89db is 89db dont matter what track it is or what album it came from.if it doesn't happen like this, then i don't see how it is normalising anything at all.The album volume and track volume shouldn't make any difference.But hey, i'm probably wrong lol!!!!!!! :D :D :D :D :D :D :D :D

That's really bad news, this might be fine for those who play Albums, but as someone who doesn't it's really disturbing to have to still use the volume myself to have consistent playback from track to track. Although I wonder if the Level Playback/Sync setting in MM4 controls this?

it applies album gain (based on my deductions).
I got zero after analysing the tracks again after applying it

I don't understand how it works.

Could you clarify?

If you level volume what is applied? track gain or album gain?

Is there any way to choose between the two?

Thank you.

btw: How did you get "zero" as offset values?
I always get little variations and I always thought it was to be expected since mp3gain works with 1.5dB steps.

Album gain is already applied.
I just copied a test album in and tried it.. it definitely doesn't come up with an option to choose. And it applies TRACK volume changes, not album (This is not true, see my post below)
I can see this because while looking at the track volume and album volume columns.. album volume should all be zero after applying is the album volume is used, but it's not.
funny thing is though, track volume doesn't zero either, it ends up around 0.2 but varies.

Actually.. no, I'm wrong.. apparently it uses the ALBUM volume to level the tracks.

strangely, once you apply the levelling, it changes the values in the track volume or album volume fields but NEITHER of them become zero consistently - which they should. Which is odd.

However, I then re-analyzed the volumes of all the tracks and album is all zero now.

I'm happy about this, however, still uneasy about using it seeing as the instructions around it are unclear and the values don't change properly upon initially applying.

actually, I said the exact opposite.
If it were to use the track volume, then you would find it would make quiet songs on an album louder and louder songs on the same album quieter - causing discrepancies.

I'm not clear either. The suggestion in 3839 is really great as it allows the user to choose. I don't want to use Album Level and want Track Level instead. I don't play Albums and thus Track Level is preferred. This clearly should be a user defined option, but I'm not clear what has been done.

It's not clear. I don't see any option to control how leveling is applied (track or Album) :-?

Any info?
