Hello Is it planned someday to implement additional higher (9-12) compression modes like in Flake? http://flake-enc.sourceforge.net/ It's not very important I think. Harddrive space isn't problem today. But it preserves other indepentent work done on Flac and give room for some extra albums on harddrive. I think development of flake is stopped. I plan to test my ~20 GB flac collection how big difference flake -12 gives me. But I still use reference implementation for my main collection. Sorry my english isn't very good. Marko

Does it make smaller compressed files than FLAC? Erik -- ---------------------------------------------------------------------- Erik de Castro Lopo http://www.mega-nerd.com/

If you like the idea of that little extra gain while sticking with FLAC (for hardware/software support) you might look into FLACCL, that encoder is still actively developed.

I don't know how accurate it is but i think it gave little more than 100 MB. I have prog rock, jazz, folk and new age music in this collection.> If you like the idea of that little extra gain while sticking with FLAC > (for hardware/software support) you might look into FLACCL, that encoder > is still actively developed.I prefer reference implementation.

Are you sure that the encoding library was improved, or just the command line? Keep in mind that 1-8 (or 0-8) are just macros for particular combinations of options that are also available separately. I'm just guessing, here, but 9-12 might be nothing more than selected combinations of options that are already available in the official flac command-line, albeit without a short, numerical abbreviation.

Flake is a completely independent codebase. When I used it years ago, I remember it being not only better compression but significantly faster as well. I believe some of the techniques used in libflake were added to libFLAC in 1.1.4. However, some of the improved compression in flake was due to options that are outside the FLAC 'subset', such as larger blocksize, greater number of prediction coefficients, and higher-order Rice codes. -Ben Allison> Are you sure that the encoding library was improved, or just the > command line? > > Keep in mind that 1-8 (or 0-8) are just macros for particular > combinations of options that are also available separately. > > I'm just guessing, here, but 9-12 might be nothing more than selected > combinations of options that are already available in the official > flac command-line, albeit without a short, numerical abbreviation. > > Brian Willoughby > Sound Consulting
