If you really want to use the full potential of FLAC, there is another string that creates smaller files.
flac.exe --super-secret-totally-impractical-compression-level(which uses: --lax -P 4096 -b 4608 -m -l 32 -e -E -p -q 0 -r 0,16)

Edit: Warning...this setting results in vvvveeeeeerrrrryyyyy sssllllooowwwwwwww processing. My P4 2.0GHz takes 1 minute to compress 5% of a 7-1/2 minute track, hence ~20 minutes for the whole track (and that's only one song, mind you).
Edit 2: Compared with simply using -8, the above setting compressed my sample track at a ratio of 99.829% compared to an instance compressed with -8 (48931KB vs. 49015KB), and the latter compressed much more quickly (40 seconds vs. 20 minutes). The moral of the story...use -8
As you see it compresses files better than -8/--best, but takes 30x the compression time!

Most interesting! I was unaware of this extra-compression, albeit, as the name implies already, impractical setting in FLAC.
Just for the records, would it please the gentlemen
Speek and
Hans Heijden to perform some encoding/decoding speed and compression ratio testing with this setting? I'm particularly curious to know whether thus encoded FLACs still
decode equally as fast as in any other compression level.
