wavpack can't compress large wav (4gb+)
Hi, I record lots of live concerts to multi track audio (24bit, broadcast wav) some shows can be 4-5 hours and some of the stereo files can get into the 5gb area...
Wavpack does a stunning job when it comes to archiving audio, but it doesnt even attempt to compress these large files. (And I don't want to split them) is there a switch or something else I need to do to allow it?

Thanks

Technically wav is limited to 4GB files. If your .wav files are bigger they are probably some extension. Do you know which? See if you can find a frontend that supports it.

Hi thanks,
these files are broadcast wav rf64,  bwf - (just with the extension .wav)
http://en.wikipedia.org/wiki/Broadcast_Wave_Format

they are 44.1, 24bit


all of the mono, and stereo files pack just fine with wavpack, im using the frontend

however once a file gets over 4gb it doesnt get compressed, it just gets skipped.


thankyou!

Use a frontend that supports rf64.

RF64 files smaller than 4 GB can be made fully compatible with WAV format.  RF64 bigger than 4 GB cannot. And apparently WavPack doesn't support RF64.

P.S. Many players don't like WV files bigger than 4GB. No problems with decoding and playback, but some problems with seeking.

Ok thanks for the info.

I'm not looking to play these.. They are just being compressed to save space..
Should I ever need the projects again I would decompress.

The current version of WavPack does not support either of the extensions that allow wav files greater than 4 GB, however this is planned for the next major release (which will be fairly soon, with any luck).

I am still planning on this as my next enhancement for WavPack (after I release a quick update for the 4.75.0 release). Unfortunately I've been working a lot on paying work the last two months, which has slowed progress on WavPack. As soon as I start testing something, I'll let you know!
