I decided to try out the excellent new WavPack 4.2 release to day with the new options. Here are my encoding speed/size comparisons this morning, for those who may be interested. Not sure if I should have posted this as a separate topic but it isn't a "listening" test, so here it is:
Equipment: WinXP P4 3.0 GHZ HT w/512 DDR RAM
Clips:
Green Day - American Idiot -- Chosen because it is short and loud (not acoustic by any means). 2 minutes 54 seconds - WAV is 30,030 kb (29.3 MB)
Tom Waits "I Hope That I Don't Fall in Love With You" (quiet and should compress well) - 3 minutes 54 seconds - WAV is 40, 403 kb (39.4 MB)
I used the following options:
-h

So, the sizes didn't change much, but as stated in the documentation, the encoding time here shows that it is much higher. I wonder if I am using the right settings? The file sizes are sometimes larger than the -h standard....
