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... -

Brotli
Brotli compression format
Version 1.0.9 contains a fix to "integer overflow" problem. This happens when "one-shot" decoding API is used (or input chunk for streaming API is not limited), input size (chunk size) is larger than 2GiB, and input contains uncompressed blocks. After the overflow happens, memcpy is invoked with a gigantic num value, that will likely cause the crash. Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm,... -

LZ4
Extremely fast compression algorithm
LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). 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... -

Snappy
A fast compressor/decompressor
Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. Snappy is intended to be fast. On a single core of a Core i7 processor in 64-bit mode, it compresses at... -

ccccd
Channel Code Copy of Compact Discs
Channel Code Copy of Compact Discs: This project has the goal to archive the complete content of CDs on the channel code layer. Here, the NRZI signal which stems from the laser-pickup of a CD player is recorded directly, providing sort of a pit-land photo of the CD. The resulting image file, in turn, is demodulated and decoded in software, i.e. within a virtual CD player. The digital audio channel code on LaserDiscs and CD Video discs can be handled as well. Note: The image extraction... -

akaidatdecode
akaidatdecode: tool for the AKAI S1000/S3000 DAT-backup format
The tool "akaidatdecode" can be used to decode the AKAI S1000/S3000 DAT-backup format. "akaidatdecode" converts a suitable WAV-file (DAT-backup signal) into a tar-file (file archive). Notes: * The WAV-file must contain a bit-transparent copy of the DAT-backup signal, signal-manipulation (for example level-scaling, filtering, dithering, or lossy audio compression) is not allowed. * The resulting tar-file for example can be imported to a disk (or image file) for AKAI samplers via the... -

diffpak
A huge files block differential compressor
A differential compresor (or a binary diff) for huge files. Unlike other tools, e.g. xdelta3, it searches for matching data through the whole source file, even if it weights several gigabytes, while using much less memory (with default configuration approx 25x less than the size of the source file). Output files are not compressed, so you can use any compressor you like with great results. It is quite fast for very similar files (about the speed of hdd, however it reads input files twice)... -
