NEW: Improved audio analysis and volume leveling (R128)

in the analyze audio menu, there is a checkbox "skip analyzed files". check this, and never think about which files have been done or not, as MC will skip previously analyzed files
you can analyze any PCM bit/sample rate, and DSD .dff files. you can also analyze the audio for video files using the same tool

Thank you, ferday.
From info you provided, figured out that I had to open up the AUDIO tree to get to the folder where the source files are stored, double click on folder to show all files, do CTRL A to select all files, and then ANALYZE AUDIO. The "skip analyzed files" was already checked (default?)
Does it matter whether you select "1 file at a time", "2 files at time", etc.?
Tried googling on the ANALYZE AUDIO data column headings but not finding a relatively understandable (to me) description of what they mean and their implication on listening. Again, it would be great if the Wiki were expanded to include this information.
I am using MC at probably close to its simplest implementation but continue to be impressed with its capabilities! :D

Just found the TAGS section of the Wiki which has a glossary of all terms including those in the column headers of the ANALYZE AUDIO data screen.
Given site thoroughness with most things, figured that there WAS a description of terms somewhere but did not associate the ANALYZE AUDIO with the TAGS function!
Thanks.

[*]Adoption of the R128 industry standard to analyze the loudness and dynamic range of content
[*]Ability to analyze audio for video files, including surround sound
[*]Smarter Volume Leveling that automatically respects intentional between track levels when playing from an album
[*]Volume Leveling works together with Adaptive Volume's peak level normalization
[*]Peak level is reported in decibels, measured as an R128 compliant True Peak, and reported per channel
This is a big topic, so I'll try to revisit it and post more details about the changes and the motivation at a later date.

Regarding this not uncommon problem https://benchmarkmedia.com/blogs/application_notes/intersample-overs-in-cd-recordings?_pos=1&_sid=0eeb1f150&_ss=r

I had recently asked about it here. https://yabb.jriver.com/interact/index.php?topic=135725.0 , But it's still not clear to me, which if any player improvements allow correction of this specific problem. If yes, how can JRiver be set up to reduce or eliminate this kind of distortion?

Hello, I read about by "turning down the gain", I could avoid inter sample peak distortions but I could not find anywhere in JRiver 33 to turn down the gain. Can someone help please? If I misunderstood the turning down gain method, is there another simple way to avoid or reduce the chance of getting inter sample peak distortions?
Lastly, I tried using internal volume, but the sound output became very quiet, is there an adjustment to make the boost the sound volume back up?
Thank you.

Using internal volume is how you would turn down the gain (i.e. reduce the volume). Have a look at the various volume leveling and adaptive volume options in DSP studio, and you'll find some options that will let you recapture most of the volume.
