A new FLAC encoder has been developed, which is proposed for inclusion in ffmpeg. The author claims that in high-compression mode, it can compress certain files better than libFLAC.

Album: Toto - Legend (in a single file)
Playing time: 72m 35s Original File Size: 768284896 bytes Computer specs: Apple PowerBook G4, 1.5GHz, 1GB ram, 7200rpm HDD. Encoders: flac 1.1.2 and flake 06 CODE flac: level enc time bytes ratio kbps dec time ----- --------- -------- ----- ------ --------- 0 1m 50s 518214304 0.675 1m 15s 5 3m 34s 496252171 0.646 1m 14s 8 13m 46s 494499692 0.644 1m 26s flake: level enc time bytes ratio kbps dec time ----- --------- -------- ----- ------ --------- 0 3m 21s 526551866 0.685 967.2 1m 21s 5 6m 53s 495548928 0.645 910.3 1m 30s 8 13m 37s 492004491 0.640 903.8 1m 14s The compression rate is comparable to flac, but it encodes noticeable slower at -0 and -5. Anyway, you have done great work so far!  Download the Mac OS X univeral binary here: direct link |

Anyway, you have done great work so far! Thank you for the feedback. It looks like I have a long way to go to make level 5 comparable to the reference encoder on PPC. At least level 8 is on par. I finally let my system run for a while to test a whole album. Here is what I got at level 8. Smashing Pumpkins - Siamese Dream playing time: 1h2m15.8s flac: encode time=1h1m35.42s ratio=0.583 flake: encode time=35m43.75s ratio=0.582 I know...it really is about time for a major upgrade...I'm still holding out for 10 good years out of my '97 IBM.  Thanks, Justin |

Here are my results for four albums lying around. CPU AMD K8 1.8GHz, 64-bit OS, everything cached in memory, so the harddisk wouldn't be a bottleneck. Included is also decoding speed of another decoder that is very sensitive to higher LPC order. Versions used: flake-06 and flac CVS.
