Cool, maybe now I can find and fix that 'infinite newlines' bug I have with it on NT so I can finally update the FLAC comparison page.

OK, finally got around to this (took me a couple of hours to get it to build). For me the problem appears to be caused by the code that shows the progress on the window title (display_progress()). If I remove that guy, problem solved. I have no idea why.

The data points I have:

3.91 binaries: both wavpack.exe and wvunpack.exe had the problem
3.96 binaries: only wvunpack.exe had the problem
3.97a compiled from stock sources: only wvunpack.exe had the problem

Bryant, hope you're watching!

Oh yeah, and see how WavPack works smile.gif

The code is very interesting. I have not delved too deep but it looks like a novel method. It seems it would be hard to prove that nothing in there is patented though. But such is the way in the U.S.A.

After running my big batch o' tests, the compression in the 'high' mode has improved a lot: in between MAC 3.96 "normal" and flac 1.0.4 "-5". The encoding time is about the same as FLAC but decode time is twice as long as FLAC.

The normal mode is 50% faster than flac -5 and about as fast decoding, with about 1% better compression.

I will have the full results on the comparison page when 1.0.5 comes out. After that, Bryant, if you're conducive to the idea it might be fun to try a WavPack+FLAC hybrid.
