Hi,

When I use the tag window to update tags (esp composer) is MC13 updating ID3v.1, id3V.2 or the MC13 database?

Thanks,
Nicholas

MC always updates its database and by default also the file tags if adding metadata to the files is supported with the used file format. MC allows to adjust the behavior. File tagging can be disabled completely or only for specific fields.

The ID3v1 and ID3v2 tag formats are used only with MP3 audio files. By default MC writes both versions (also this can be adjusted). The older v.1 supports only certain basic tags. The v.2 supports various standardized tags and an unlimited amount of user defined tags. The composer tag is one of the standard ID3v2 tags and it will be updated by default.

I'm updating a bunch of files now.  As I go through and update something like a track number, it takes MC13 several minutes to update the tag.  I did a couple albums today, and now the queue is 145 items long and has been chugging away for hours now.  It's eating up 8-70% of my processor for hours and hours at a time.

Something's wrong.

Not normal.

A network drive?  Virus checker?

I turned off my virus software and Online Armor, took the external drive off the hub and plugged it directly into my computer, and updated the tags from the library about 20 minutes ago.  588 files.  It roared through the first 60 or so, and now it ticks through one file every five minutes or so.  It's just crawling, and sucking up the processor on my computer up to 70-80% at times.  Mostly it's 8-30%.

[ayoob]

I just cancelled the 588 file update and just picked one 20-track album.  It ripped right through the first fifteen and hung on the 16th.  I cancelled and counted forward 16 files and just updated that one, Library from Tags.  It took a couple of minutes, but it finally went through.  Same with #17.  Then the rest as a batch, none of which hung.

Then I went back and selected all 20 of the same tracks again and updated Library from Tags again, and this time it was almost instantaneous for all 20 tracks.

Virus checker or something similar.  It's not MC.

Thanks for the info Alex.  How do I know if my mp3's use id3 v.1 or v.2?  Does MC13 show this somewhere?

Cheers,

ayoob,

I just tagged a mixture of 388 FLAC and MP3 files in 12 seconds on an older PC (Athlon XP 3200+, a local, almost full 300 GB sata drive). The files contained padding area that reserves some empty space for tag changes so there was no need to rewrite the files even though these file formats store tags in the beginning of the files (Vorbis/FLAC comments and ID3v2).

By default MC includes some padding when the files are created or tagged for the first time. Small textual tag changes should be almost immediate. A worst case scenario could be embedding high resolution cover art to big FLAC files through a slowish old wireless LAN. The padding area is only a a few kilobytes so a complete rewrite would be needed. For instance, if the file size is 50 MB and the actual practically achievable network bandwidth is about 5 mbps (= 625 KB/s) tagging would probably take about 3 minutes (read 80 s + write 80 s + some additional time for local file operations, network congestion, etc).

You can select a file and click the very first text line in the "Action Window > Tag" to open the "detailed format info" window. It shows a direct tag dump from the file.

Here is an example of the displayed info:

You can adjust the ID3 tagging behavior in Tools > Plug-in Manager > Input > MP3 Plugin > Configure, but the default settings should be fine.
