From the Maximum Compression home page:
QUOTE
[WinZIP 11.0 beta] now also has a special algorithm to compress .wav files!. Research done by Guillermo Gabrielli shows the audio compressor used for this is WavPack (using Lossless, High compression mode).
Is it true and if so legal?

More info from the guestbook:

>winzip v11.0 beta is out ..

The audio compressor is WAVPACK. The WinZip 11 archives can be decoded with WVUNPACK (Wavpack decoder). According to WVUNPACK -ss (Super Summary) it's using Lossless High compression, but no Extra:
WVUNPACK -ss MWZ.zip

Does the compressor use the switch improving the ratio on mono material? If it's not the case, may David suggest to the editor to support it immediately (I guess it's not too late and that way there won't be any future incompatibility issue between different WinZIP implementation)?

but is 4.4 considered to be stable already? using the most up-to-date WavPack would be obviously the best, but maybe the official, final (non-alpha, non-beta) new WavPack release should be the first. Besides, such a 'new' zip created by WinZip 11 will be incompatible with other archivers anyway, for the time being at least, and the similar problem could occur every time when WavPack is updated in the future, to 4.5, 4.6, ... ,5.0... In reality, most probably they (WinZIP devs) will update the WavPack part less frequently than WavPack is updated, and as long as both WavPack encoder and decoder in WinZip remain the same version, there will be no incompatibility issues.
anyway, I too would like to say congratulations smile.gif

IMO that's not a problem; most WinZip users are not familiar at all with WavPack and will just go 'goshwow' that their .wav's are suddenly compressed smaller than before. They wouldn't care if a newer WavPack compresses 1% smaller than before, as WavPack already compresses waaaaaay better than plain old WinZip can ever achieve.

Oh, and congrats too, David! It's nice to see these advanced free algorithms make it into the mainstream. smile.gif

Although I wonder... is it possible that there's a Corel guy lurking in the forums, which explains how they managed to contact David before he managed to send and email to them... biggrin.gif
