Mp3tag slow


#1

I tried to import a folder of mp3 tracks and found mp3tag 2.29 took almost a minute to import one album !!

Is there something i need to tweak, was hoping it would be much quicker.


#2

These files have probably a lot of invalid padding (many zeros) at the beginning of the file or very big embedded cover art.

Try to remove the ID3v2 tags and re-write them via the undo feature - this should do the trick.

They do have ID3v2 tags in them, which would be at the beginning of the tracks.

It's difficult to do re-writes as i have thousands of tracks tagged this way.

I'm unsure why you would say the padding is invalid. winamp, fb2k seem to read them fairly quickly.


#4

AFAIK, neither Winamp nor foobar2000 are detecting invalid padding. Can you provide me one of the problem files, so I can analyze them?


#5

That is quite possible, which raises the question why detect the padding at all in mp3tag ?

As far as i understand padding is there to reduce time taken for subsequent re-wites. I think this is a good idea when small changes need to be made to lots of files at a time. Especially if they are ID3v2.


#6

Mp3tag detects invalid padding, because otherwise it wouldn't be possible to remove the invalid padding - I'm not talking about regular padding within the ID3v2 tag boundaries here, but about invalid padding outside the tag which was added by MusicMatch IIRC.

This won't be changed.


#7

OK, is there a tool i can use to find if an mp3 does have invalid padding ?

..now its clear what kind of padding we are talking about :slight_smile:

I also wonder whether i should import and mp3tag alone for some time...

does mp3tag build up a database of what it imports, so in the future its quicker to access imported albums ?


#8

Nope and this is not planned either. :slight_smile:
