I made reference in the Yalac thread when I posted my initial results that I had never previously considered WavPack's- -f option, and was surprised at the speed and compression. It's impressive that WavPack can compete with FLAC -5 in speed, and still surpass Flake in compression.
I also find it interesting that the changes in 4.4 are geared toward faster, less processor-intensive decoding, and that has come at a small cost in compression. I must admit, I think I may be sticking with -h (-hh), but it's very possible that I may switch to the new -h for a little faster decoding at the cost of a few MiB, as it seems the difference to me would only be around 4MiB per GiB encoded, which really is negligable.
Edit: David, can you see the presets changing at all for the release version, or will I be able to rename to 4.4 and leave the results as is?
