Audio analysis (do I have to do it again?)
« on: April 21, 2024, 08:16:27 pm »

I have over 250,000 tracks in MC. All of them have been analyzed for volume leveling etc. But now, when the box is checked to skip tracks already analyzed, MC wants to do it again. Why? And how can I identify the few remaining tracks that haven’t been analyzed if the program can no longer distinguish?

Don't know why it's trying to redo those already done if the correct box is checked, but....

In standard view go to the "Files" view.  On the title bar (where the categories are listed), right click on it, this should bring up a box listing separate fields.  Scroll down to "Volume Level (R128).  Select that and it should create a new category listing.  You can then left click on the title bar where it should now have "Volume Level (R128).  This will list all files by their volume level.  Any that are blank have not been analyzed.  They should be grouped at either the bottom or the top of the file listing.

Highlight those and run the analyzer.

How long ago did you run the analysis? Because it might be trying to re-analyze the files for the newer waveform or maybe HDCD data.

Some, many years ago. Maybe as far back as 8 years. I’m seeing the numbers in the Volume Level (R128) column and these same files are being queued to re-analyze.

Following up on this because MC is trying to reanalyze all files that have data in this category. Why is it doing that? It's very frustrating.

EDIT: it's wanting the "audio CRC" data. Do I have to rescan my entire 250k+ song collection for that?

Audio CRC is the latest bit of metadata added to the audio analysis feature. IMO, it and any new data added to audio analysis in the future should be optional like Waveform and HDCD is because having to re-run audio analysis on very large libraries is very time consuming (especially if you have backups in place and have to sync them) for little to no benefit from having the new data.

I have the Audio CRC field set to not write to files, and I clear the field after import and audio analysis runs in MC for new files. It's kinda annoying having to do that, wish it was optional too.

OK, so at this point there's nothing I can do about it? Too bad.
