During the development please make sure Stereo Playback from Video is taken care off. To me it seems that the impact on Stereo Video playback is huge. If I play 24/96 Audio files from CD I have an Audiophile performance, when playing this kind of format from Music Video it's not (dynamics are gone) Playing around with Adaptive Volume does not do much good. So my request, please make sure that Stereo Streams from Video are handled without tweaking, I would like it pure, Audiophile....

Check the Dynamic Range (DR) and Dynamic Range (R128) values for both files.
What you are probably hearing, is exactly what R128 was designed to do. R128 plays back both files at the same volume level, regardless of their dynamic range.
Previously, tracks with a compressed dynamic range (a lot of modern music) would sound a lot louder than well mastered tracks with a lot of dynamic range.
Subjectively, most people will pick the louder of two tracks as sounding "better" regardless of how it was mastered.
When you eliminate the difference in volume between the two, you can now identify which track is more dynamic.
So the move towards R128 in broadcast now discourages the use of compressors when mastering music, because all it does is make your music sound worse, rather than making a trade-off between dynamics and loudness. (because you don't get the loudness benefit from it any more)
And if you just want to play videos at full volume with volume leveling disabled, you can set up a separate zone for them using Zone Switch, and disable volume leveling for it.

Hi,
Is this feature can be used (understand: compatible with) with a room correction system placed after my MC computer ?
When I says "room correction system", I'm thinking about Trinnov or Audyssey.
Is there any link between adaptative volume and the audio analysis feature (R128) ? Is the same "thing" ?
I can not tell the difference between both terms.
Regards.

I don't see any reason it would not work.

Volume Leveling will adjust the volume of analyzed files during playback so that the average volume is the same. (with a fixed target of -23 LUFS average volume)
If you have a mixed playlist with tracks from lots of different albums, it will mean that the volume should not change between the tracks as it would without volume leveling.
Files from the same album will have one adjustment for all tracks. (to keep intended differences in volume between those tracks)
Adaptive Volume tries to make playback as loud as possible. If volume leveling is not enabled, tracks will be adjusted individually to be as loud as possible, so there may be large variances in volume between each track.
If your files are analyzed, adaptive volume can be combined with volume leveling. This means that all tracks in the current playlist are equal in volume, but the playlist itself is made as loud as possible. (while still keeping the tracks at the same volume)

Thanks for letting me know. Will try to play with this.

All these features are optional. If you want it "pure", then just turn it off, and you get the audio as it was encoded in the file.
