I have a ripped album consisting of 5.1 flac and and 10 channel wav (decoded Atmos).  All tracks on album are analyzed and there were no errors completing this task.

When the 10 channel wav files are played as part of the entire album, when it gets to the wav files volume leveling reduces level for these files by almost 11db.  As a result, the wav tracks are much too low in volume (much lower in volume than the 5.1 flac tracks).   Adaptive volume doesn't help here.  Everything is made louder, but the 10 track wav are still much lower volume than the 5.1 flac files.

If I start playback of the same 10 track wavs in their own playlist, without the other tracks in the album, the volume level is reduced by only 3db, and this seems to be at the appropriate level that would match the flac files volume. 

In each case, the "playlist" only consists of files from the same album.

So, why the difference in how much the same file's volume is reduced when playing back as part of the album?
Any other configuration to look at?
 
Thanks

I've noticed this too... some but not all hi-rez files play back much higher volume than 44k files when using VolumeLeveling.

I usually have over 50 hours of music in my PlayingNow from lots of albums, and even with VolumeLeveling on... I still have to constantly adjust the volume between albums.

The volume differences affects all sampling rates.

My issue is with a very small playlist (one album) so I'm not so sure this is same issue.   

When the 10 channel songs play, their volume is not just a couple of DB lower but rather 10-15db lower ( based on how much I need to increase the internal volume control).

So, you're saying you've encountered situation where volume drops this drastically?

I've always mixed playback for 5.1. 4.0 3.0  multichannel with 2 channel and never had anything like this happen before.

Anyone have a suggestion for what to look at to troubleshoot this?  Again, I'm not talking about a small difference between volume levels, but rather something that is like a 6 - 10 db difference in the volume levels when switching between 10 channel and the 6 channel tracks.

Could you mail me two files that seem to play at really different levels?  I'm matt at jriver.

Thanks.

I'm marking this as solved. 
After going back and forth with Matt, I realized this is a result of me considering a bluray as one "album", and that's just wrong.   
What got me going down this path is the tagging software, which does consider this the same "album", and numbers the tracks accordingly.
In reality, the Atmos tracks are contained in a separate output file than the 5.1 tracks.  It's not really one "album" but rather a bluray.

As suggested by Matt, what works nicely for this situation is to have a different album names for each set of audio tracks, 5.1 and 10.   Same advice for naming might be needed for any bluray that is providing multiple versions of the same songs.

To provide a little more detail, there were two tracks at really different levels.  Volume levelling understood this, but they were on the same album so we then assume the difference is intentional and preserve it.  I suppose we could make doing album based volume levelling optional, but this was kind of a special case.  Simply putting each file on a new album solves the issue as well.

I suppose we could make doing album based volume levelling optional, but this was kind of a special case.

If this was done, would it be track based volume leveling? That may be pretty appealing to some actually and could actually make a good audio improvement to MC33 for those who like that (e.g. those used to using ReplayGain track based gain, etc.).

If it's track based then what is it leveling to? Isn't that just what turning on adaptive volume in peak normalise mode does?

[whoareyou]

Peak normalize increased volume equally across all the tracks so playback volume differences remained the same but at a higher volume.  Do you think it should have worked differently?

There was an option for track-based volume leveling in previous versions of MC, but was opted-out a couple of years ago for a reason I don't understand.

Please provide that feature again! It is useful when for instance a custom 'album' is created from different audio sources.

Thanks!
