Description Gale Andrews 2012-05-12 18:37:26 UTC

Exporting a WAV file that has BOTH a Comments tag containing exactly 61 characters AND three other supported tags will create an invalid file. VLC, Foobar2000 or Windows Media Player will not play this file. There could be other combinations that fail. 

This could be a bug in the tag library we use for WAV metadata or in Audacity. If a tag library bug it is probably yet another good reason to move to taglib (see bug 364).

Hard to test this now as Gale's site with the test data is no longer extant

Comment 2 Steve Daulton 2019-05-13 18:39:36 UTC

I've been unable to reproduce this bug, and unable to find the file "sprookjes_01_andersen_64kb.zip". Also, I've not found any other reports of this bug.

Without more information I see no point in keeping it open.

Marked WORKSFORME on the basis of Steve's Comment #2
