Isn't VDJ analysis enough for you?
VDJ analyzes tracks after loading them onto the deck, but it can analyze any track highlighted in the library. You can prepare the analysis by first scanning the entire library.
Analysis results can be saved to file tags, so you only need to analyze the entire library once.
Standard analysis includes beats at the beginning and end of the track, while advanced analysis scans the entire track and builds a beat grid with variable tempo.
Track key and volume are also included in the analysis.
You can find the appropriate settings in MallMuzik/opcjeVDJ.
Alt+s to the search field, type anal, and press enter.
Best regards, Zenek

VDJ has AutoGain that should help with normalizing.

if your music library are in MP3, there used to be a small program called Mp3Gain that could normalize all your Mp3s in bulk. not very useful if like me your library is in flac though.

there is also  Goldwave which I think  can also normalize files in bulk 

Hope this helps

Yes, I'm sure it would be, and I've looked for it in the vdj settings, and I found fluid analysis,l and some stuff to do with beat analyzing. Which one do I use, and how do I get it to scan my entire library? Thanks.

In VDJ, in the disk panel, place the cursor on your music disk and press Ctrl+Alt+e until you hear "folder recurse." Confirm the recurse by pressing "e."
Allow a moment for all music files from each subfolder of the selected disk to display.
You can check the number of files in the file list by pressing "a" twice quickly.

Then, go to the file panel and select all files (Ctrl+a), then using the same method (Ctrl+Alt+e), select analyze, and confirm by pressing "e."

The analysis will begin, so give your computer a moment to rest.
You can check the analysis status with the Ctrl+Alt+Space shortcut.
For everyday playing, it's enough to have the following options set:
analyzeSongsOnView; Yes
setTagsAuto; Yes
In MallMuzik/OptionsVDJ, use the F1 key to hear help for each option.
Best regards, Zenek

Hi all. Thanks, Zenek, for that info. It worked very nicely. my next question is, will this analysis automaticly set the gain on the files, or is that what the autogain is for? One more thing--it seems that the pitch on some of the songs, especially in an automix playlist, seems to be not correct. Is there a way to make sure the pitch stays where it should in the original file? Thanks for any help.

The analysis only recognizes the file's initial volume, then autogain adjusts all files to achieve the same volume.

As for maintaining the same pitch, search MallMuzik/optionsVDJ by entering "pitc" and "key"; you'll find several options there to prevent the pitch from changing.
Help for each option can be heard by pressing the F1 key.
