Pearl Jam - Ten (new european version) / Track 11: Release / Length: 543.426 seconds
System: Athlon XP 3200 - 1GB DDR400 - NForce2
Flac version: libFLAC CVS 20060425
Flake version: flake-06
encode | ratio | bitrate | speed | dec. speed
---------|-------|---------|--------|-------------
flac 8 | 0.534 | 754.? | 11.93x | 192.30x
flake 8 | 0.533 | 752.1 | 23.31x | 187.11x
flake 12 | 0.531 | 749.8 | 4.27x | 162.23x
Commandlines for encoding:
timethis "start /realtime /b /wait flac -8 test.wav -o NUL: -f"
timethis "start /realtime /b /wait flake -8 test.wav -o NUL:"
timethis "start /realtime /b /wait flake -12 test.wav -o NUL:"
Encodes were done three times, fastest run counts. Spread between runs was small, no more than 0.1s. Speeds are rounded.
Decoding speed was measured with Foobar2000 0.9.1, 10 passes, no dsp, high priority, buffer in memory.
Flake -8 file decodes about 44% faster with flacdec.
A 95.5% speedup. Impressive. Flake -8 is my new god.
I still miss some options, most important to me is -V as i like to overclock my hardware. Veryfying doesn't slow encoding down much anyway. Also reading from stdin doesn't seem to work on windows, it will say "invalid wav file: -" and then proceeds create a 0 byte flac output file, another feature it could do without
For the rest it's nothing metaflac can't handle.
