My results (see reply #7 above) show FFmpeg -threads 1 decoding right in between FLAC with md5 and FLAC without md5.* ffmpeg -threads 1 decodes nearly twice as fast as reference flac at -5, but several times slower at low block sizesOf course I dove into that, because if FLAC can be twice as fast, that would be great! But I cannot reproduce, not on Linux nor Windows, not on SSD nor ramdisk. Can you check your results and see whether a different way of collecting times gives you the same result?
@ktf, of course there is nothing wrong with the file? The blame is squarely on ffmpeg?I see nothing wrong with the file. Maybe the problem is that it consist of a single block?

It's at least partly due to the LACE/noLACE postprocessing for low bitrate voice.
The ability to change between playlist sidebar and album list. I use F2K "for ever" in windows and now it seems another program. Almost crippled.
When my improvements are over, it can be a codec that everyone can use.
Why is there such a huge difference in size between the encoder (676 352 bytes) and the decoder (5 625 344)?
