This isn't a bug report, and it isn't a suggestion, it is a query as to what could be happening in a strange case.

I received several long files (single mp3 of complete sides of LPs).  When I load them into Cooledit they seem to be truncated, a few seconds are missing from the ends.  Note that these file only have V1 tags, and are VBR.  On an off-chance (a whim?) I looked at them in mp3 TS.  They did not show a red length, but despite that I ran the VBR header repair on them.  After that Cooledit had no problem loading them correctly.

Note that another editor (DC Millennium) was able to load them correctly before the repair was done.

I know this isn't an mp3 TS problem, but I just wondered if anyone has an idea as to what is going on here.

A VBR header contains more complex data than just the specific one that Mp3/Tag Studio quick checks for the red/black test. For a non-corrupted VBR tag this test should be enough, but if the VBR header is incorrect or corrupted, strange things may happen even though it is reported as ok in the quick test.

Another theory is that the files did not contain any VBR headers at all to begin with, before the Mp3/Tag Studio repair on them?

That is possible (no VBR headers), but I will have to download one of them again to check.  If that IS the case, why would fixing a non-existent header make the file readable in CoolEdit?  (And why was DC Millennium able to read it in either case?)

CoolEdit might assume that all files without VBR headers are CBR files, while DCM might not (and rather check to make sure), and that would cause this behavioral difference.
