Topic: Problem correcting VBR headers< Next Oldest | Next Newest >

Hello Magnus,

I am having a problem with the section of the program which is designed to repair VBR headers.  I have many (about 10,000) files which were encoded with a Xing VBR  at 320K, but the file info on all of them has bitrate=32k.  Needless to say, the duration of these songs is way off.

I tried using MP3Tag/Studio to correct this problem, but its results too were way off.  It changed the bitrate to 106 and the length to 9:28.  The CORRECT numbers (as calculated by FooBar) are bitrate=202 and duration/length=4:57.

Interestingly, the correct VBR (202) is reported by MP3/Tag Studio in the "Browse/Edit Tags & Flags" section BEFORE the repair, but is changed to the incorrect value (103) after the repair.  Similarly, the song length reported there prior to the repair (4:59) is VERY close to the actual length of 4:57, but this info too is changed to an incorrect value of 9:28 after repair.

Any idea what to do??

Thanks,
Randy

Magnus,

One other piece of info you might find helpful...

There is a program called vbrfix at  http://www.willwap.co.uk/Programs/vbrfix.php
that properly corrects the headers.

It is open source, so you might be able to identify where your algorhythm differs.

Thanks for the info, if you send me a sample file having this problem I can take a look at it.

Magnus,

How exactly do I send you the file as an attachement?  Do you have an e-mail address I should use?

Randy

Yes, there is an email address on the "Contact info" page of the Mp3/Tag Studio website (http://www.magnusbrading.com/mp3ts).

(I don't want to put it here in text format, for spam reasons)

Try to cut off a chunk of it in the end (keeping 1-2 MB should suffice) with the trime tool (if the size calculation is incorrect there too you might have to try different cut-times to get it right).

Magnus,

Sent you 2 files.  Please ignore first one ("If it doesn't come naturally).  It doesn't work either, but info in e-mail is incorrect regarding correct values.

I sent you "Midas Shadow" and correct info on that file.

It is smaller so should go through.

Randy

PS:  I have more if you need them...plenty more...
