Compresses music from 1/50th to 1/100th its original size by removing dissonant parts of sound and also optimizes it for lower speaker-stress, dynamic equalization (2-3 times less hearing stress at high volume), non-compression modes and much more.

Major looseless compression algorithms library and documentation. First project: Arithmetic, Huffman, LZ77, LZ78, LZW, RLE. Second project reimplements Deflate. Documentation explains major Entropy Compression Methods.

Compression/decompression library, capable of operating on a stream and intended to be used on systems restricted in code and stack size.

LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language. I expect a severe performance degradation, but I leave optimizing for speed to other people.

A Huffman Coder/Compressor.

THIS PROJECT HAS BEEN MOVED TO GITHUB: http://github.com/drichardson/huffman

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/

Help implement an industrial strength Burrows-Wheeler transform compressor! Initial release covers block-sort, MTF coding, RLE coding, Huffman coding

Iterative Compression Algorithm: trying to prove Shannon was wrong.

Kexis - A lossless WAV file compressor. Kexis' main goal is to develop prediction and encoding schemes to minimize compressed file size. Kexis strives to be the premier lossless sound encoder.

LICOM is a compression/de-compression tool that sits in-between the browser and content from the server. It aims to facilitate compression of ASCII text, RTF, DOC, PDF, HTML, GIF, JPG, BMP and similar filetypes.

LZO is a portable lossless data compression library written in ANSI C. It offers pretty fast compression and very fast decompression. Decompression requires no memory. In addition there are slower compression levels achieving a quite competitive compres

Rsync friendly encryption that runs on the UNIX command line. Encrypt a file and backup the changes to an untrusted host.

Open MP accelerated implementation of distributed network storage system.

NuFX or "ShrinkIt" archives are the de-facto standard in the Apple II (and A2 emulator) world. NufxLib is a full-featured library of functions that manipulate NuFX archives (.SHK, .SDK, .BXY). NuLib2 is a command-line utility built on top of NufxLib. THIS PROJECT HAS MOVED TO GITHUB https://github.com/fadden/nulib2

OzVM is a simple, lightweight, secure virtual machine. The current target application of OzVM is OzStream, allowing platform-independent self-decoding data, which abstracts encoded data from client applications.

This program parallelizes the BZIP2 compression process to achieve a near-linear performance increase on SMP machines. On a two-processor Xeon machine, the speedup is around 180%. The tool's main purpose is to aid performing heavy-duty server backup

rpmdiff is a utility to create a binary patch from one version of an rpm to another. This binary patch can then be distributed to end-users of a distribution who have installed the first version of the rpm and they will be upgraded to the second version.

A simple project for use with SDL that loads a zipfile into memory and automatically converts all known files (such as text, graphics, fonts, and sounds) into data that is ready to be used in a game or multimedia project. It is the SDL equivalent of an A

Shoelacer generates C code to compress short strings based upon provided sample data. The resulting routines use small models with low memory overhead.

TNT Mocha Backup Platform Independent backup utility written in Java. Uses ZIP files for data storage. Now supports file permission backup for restore by standard utilities in linux such as unzip.

Tcl Channel drivers for gzip'd and bzip2'd files. Read and wirte compressed files directly from within TCL. This library allows you to use two new commands (openBzip and openGzip) in your tcl scripts. Since they take exactly the same Options as the st

This software zips and unzips a .txt file, using the Huffman encoding algorithm and the list and tree data structures. The result files are named zippedFile.txt and unzippedFile.txt and can be found at the same directory as the Text Zip executable file.

This project should be deleted because the name "Garp" was already taken. This project will continue under the name "Arpix" (that is, if the SourceForge staff approve my "Arpix" project).

A compression engine based on the Huffman trie algorithm. The algorithm is pretty cpu-light, and as such, runs much more quickly than RAR or other 'heavy' algorithms, but could still achieve decent compression. Use with tar for multi-file archives.
