Thanks to Arindelle for taking the time to write this detailed explanation. Strange as it seem, I really do believe I understand what is going on (that the analysis stats do not change the original sound files, that they are only added as tags for use if and when I choose to use the DSP features during playback, etc.). 95% of my listening is to 20th/21st century "modernist" classical music, which has an immense dynamic range, both among and within tracks. My primary purpose in creating a cache of music via MC's Sync Handheld function is, needless to say, to convert tracks to a lossy format that will take up less space, whether it be on an SD card or a portable USB drive. My choice of lossy format at present is OGG-Normal. The original tracks in my library are in a variety of formats: flac, wav, mp3, higher resolution ogg. But for me there is also a secondary purpose in creating this cache. It enables me to apply a certain amount of volume leveling in advance, so that I can then take these files around and listen to them on my office computer or on any number of portable devices using a variety of playback apps. That is why MC's facility for applying DSP Volume Leveling during the conversion process appealed to me. Of course you can argue that if I were a purist this is not something that I would want to do, and I certainly respect that argument. But there is very little point in being purist if the result is that the music you are trying to listen to is simply too soft to hear on the subway, or in your work environment -- or too loud to hear without bothering other people. (And you would be amazed -- or perhaps not -- at how low a tolerance most people have for Boulez and Schoenberg, coincidentally the composers of the tracks for which I posted the clipping screenshots.)
From my perspective we always come back to the same place: I used a feature in MC following MC's instructions (as quoted in my last post), and the result was that I got unlistenable tracks, unlistenable because the level was raised so high as to cause serious clipping. When I run a straight format conversion, either using Media Center or Audacity or any other software, I never get this, which leads me to believe that it has nothing to do with my sound card or any other component on my system. So I see this as a bug in the MC20 software, and as a bug it is something that JRiver should address. It seems to me that JRiver has two alternatives: either to fix the bug, or to remove the "Apply DSP Settings" option from Sync Handheld. I am at a loss as to why Volume Leveling and Adaptive Volume should work during playback (and yes, I have set import and ripping to analyze all tracks automatically -- and the tracks I posted were re-analyzed immediately prior to running Sync Handheld), but not during format conversion. Again, this is looking like a bug, and one that is serious enough to be addressed in some fashion.
