    Zstandard

    Zstandard

    Zstandard - Fast real-time compression algorithm

    Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8478. The negative compression levels, specified with --fast=#, offer faster compression and decompression speed in exchange for some loss in compression ratio compared to level 1, as seen in the table above. ...

    LZ4

    LZ4

    Extremely fast compression algorithm

    ...It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open-source software using a BSD license. This benchmark simulates simple "static content transfer" scenario such as OS Kernel compression or video game's static assets (text/images/tables/scripts/etc) which loading from Flash Memory / HDD / SSD. In this case, compression time is completely ignored. Because only content developers compress the data at once and usually they don't care about its computational cost. ...

    gzzzzzz

    makes a "big" gzip file

    gzzzzzz enlarges a given file 6 times and writes it as a gzip file. It therefor can be "decompressed" (which makes it 6 times smaller) with the standard gzip. This shows that gzip (and deflate and any compression tool that uses one of them) but also, as I expect, any other compression format can be used to augment data significantly.

    TTA Lossless Audio Codec
    Lossless compressor for multichannel 8,16 and 24 bits audio data, with the ability of password data protection. Being 'lossless' means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original.

    Huffman Stuff

    I want to test some ways to store the data for the Huffman Tree

    Lectures on Huffman Code mostly focus on creating the Huffman Tree and converting the given data into the new bitmap. But what about the informations needed to create the Huffman Tree? They must be stored as well. With this project I want to test some possibilities to store these data. gmp,h is needed to compile. See: http://gmplib.org/

    Gemc

    Gemc

    Prepare your CD images (BIN,CDI,NRG,CCD or similar) for compression

    Gemc lets you prepare CD image files (such as BIN, CDI, NRG, CCD, or similar) so that they'll compress far better in programs such as WinRAR. HERE`S HOW TO USE IT: Run the CD image file (i.e. filename.bin) through GEMC to create an ECM file (i.e. filename.bin.ecm). Compress the ECM file (i.e. filename.bin.ecm) using your favorite compression program (i.e. 7Z,RAR,ZIP..). Back up, transmit via Internet, or whatever you normally do with CD images! When you want to burn the CD again,...
