    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (113 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

  • Precomp: More Compression for your Compressed Files (3 Comments)

    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them. Christian Schneider’s Precomp comes to rescue by undoing the harm.

Fixed point OpenLPC codec released under LGPL

Posted by Sachin Garg on 20th October 2005 | Permanent Link

Phil Frisbie of Hawksoft announced in this comp.compression thread that his commercial fixed point OpenLPC codec will now be dual licensed as LGPL or commercial software.

I am pleased to announce that my commercial fixed point OpenLPC codec will now be dual licensed as LGPL or commercial software. The fixed point version of the OpenLPC codec is suitable to run on hand-held devices with CPUs that do not support hardware floating point math such as Arm, Intel PXA250, and other 32 bit CPUs. The fixed point codec is fully interoperable with the floating point codec, so developers can continue to use the floating point codec on desktop computers or servers. It can be downloaded now as a separate archive, and it
will be included in the next release of HawkVoiceDI.

Go to the HawkVoice page at http://www.hawksoft.com/hawkvoice/ for the latest information, and http://www.hawksoft.com/download/ to download the source code.
