When loading a a WavPack file into Songbird it shows the incorrect track time. It shows the other tags, artist, etc, correctly. After playing the track for a few seconds, the track time updates to the correct time. And stays correct from then on.

Does anyone have an idea of why this is? I was thinking that maybe it's due to the Ape or ID3v1 tags. Reading some other posts on this board I'm wondering if it has to do with WavPack files having the metadata at the end of the file?


Does anyone know why WavPack supports only ID3v1 and not ID3v2? Just curious...

File tags don't store the duration of a file, and those tags are at the end of the file, not the start.

Seems like Start Time and End Time are part of the extended tag for ID3v1 (from wikipedia), no?

How would a player determine track length then?

Start time and end time as arbitrary points to exclude portions of audio that the user doesnít want played, yes. Duration, no.

This kind of basic and quite essential technical information should be an indispensible component of the header of any audio format. Granted, there were issues for a while after the large-scale debut of VBR MP3, but thereís no excuse for that sort of thing now (and I know the developer of WavPack is above it!).

Iím not sure why ID3v1 is supported at all, but my uninformed guess would be that ID3v2 was skipped in favour of the more flexible (e.g. field-neutral) APEv2.
