Freeware: Compression

	CyberArchive  License: Freeware
	Cyber Archive is a data compression and archival program which also serves as a demonstration for the Cyber Compression Suite and Cyber Operations' data compression services. Our service includes taking your existing data or file format and creating a matching compression algorithm for maximum optimization of the data structure. Using our large array of compression algorithms and strategies we can produce a product that far outperforms off-the-shelf compression engines such as zlib. We can custom produce a compression algorithm with emphasis on throughput, compression ratio, memory requirements, or any other factors that are important to the customer. Numerous algorithms working together in Cyber Archive allow the proper emphasis on speed, compression ratio, and memory requirements for a particular application. Cyber Archive includes an abundance of algorithms, but is also designed to allow new (or special purpose) algorithms to be easily integrated into the system. A sequence of algorithms is applied to raw information based on several factors. Some algorithms are used for speed critical situations. More complex algorithms are used when maximum compression is a priority. Cyber Archive can determine the most effective algorithm based on heuristics of the data being compressed, and the required data throughput of the system. Cyber Compression Suite is OS independent. Cyber Compression Suite compression methods and algorithms include zlib, LZP, LZFast, arithmetic encoding variants, BWT, and the Markov model based X1 algorithm. Please visit the Cyber Operations website for more information on CyberArchive including a whitepaper on our Compression Suite. Author: Cyber Operations, Inc.| Date: 15-11-2006 | Size: 647 KB

	NTFSRatio  License: Freeware
	NTFS offers file based compression but the compression rate isn't displayed anywhere. For any folder on an NTFS volume, NTFSRatio shows the size and the compression rate of this folder and also of its subfolders. Compression and decompression can be done inside NTFSRatio with immediate review of the result. Results can be printed or exported. NTFSRatio can be called from the Explorer context menu of any folder. Author: JAM Software| Date: 22-10-2007 | Size: 946 KB

	Pixel-Zip Decompressor  License: Freeware
	Pixel-Zip is a raster image compressor and decompressor designed specifically for the graphic arts and related markets with especially developed large file, 16-bit and native CMYK mode compression support with algorithms tailored at maximum colour and quality retention. You may not know this, but many similar technologies in the market actually convert CMYK images into RGB, compress and store this RGB data and then decompress and convert RGB back to CMYK, distorting and changing colour — a devastating effect in the graphic arts business. Maximum lossless compression is delivered whilst noise and grain can also be removed at the same time, improving image quality further. Pixel-Zip's cutting image compression algorithms are based on Wavelet Analysis combined with several other unique technologies, which puts the product far ahead of any similar software in the image compression field. It is possible to achieve 200 times compression with no image quality loss! Author: Pixel-Zip Team| Date: 01-05-2007 | Size: 753 KB

	BIGSPEED Voice Compression SDK  License: Freeware
	BIGSPEED Voice Compression SDK is a simple, low-complexity, low-cost voice engine for quick development of VoIP applications. It incorporates audio recording/playback and voice compression/decompresion in a single COM automation object, along with some advanced voice processing features.    The used audio format is wideband, 16kHz, 16Kbps, PCM. The compression ratio is adjustable and can vary from 4:1 to 50:1.    A lot of bandwidth can be addionally saved thanks to the silence compression. A voice activity detector (VAD) with an adjustable threshold level is used to distinguish between regions with normal speech activity and those with silence or background noise.    An optional echo suppression can be employed thanks to the robust double talk detector. When a double talk situation is detected, the output signal is faded (half-duplex).    An automatic gain control (AGC) system is implement with a dynamic range 10:1. A noise reduction is performed on the microphone signal to decrease the white noise.    BIGSPEED Voice Compression SDK utilizes an elegant event-driven paradigm for easy integration into Windows applications. A special attention is paid to provide responsive user interface while maintaining low CPU usage. Carefully designed set of properties, methods, and events offers great flexibility to develop innovative communication software. Sample applications are included in Visual Basic .NET, and Delphi 7.

	7-zip++  License: Freeware
	7-Zip can also open any file format that uses a supported compression method. For instance, it is possible to open MSI files in 7-Zip that include the files to be installed with the file itself (otherwise, the files are stored in CAB files, also supported). This makes 7-Zip a good tool to check if a file is an archive. For ZIP and gzip files, 7-Zip uses a modified implementation of the DEFLATE algorithm that is tuned for higher compression levels at the expense of speed. This implementation is also used in the AdvanceCOMP tools. The native 7z file format is an open, modular architecture which allows it to contain files compressed Unicodeusing different algorithms.7-Zip supports a number of other compression (and non-compression) archive formats. These supported formats include ZIP, Microsoft cabinet (CAB) files, RAR, ARJ, gzip, bzip2, LHA, tar, cpio, rpm and Debian deb archives.-Zip also supports ISO CD/DVD images.

	Chilkat Create Self-Extracting EXE from Zip  License: Freeware
	Create self-extracting ZIP files optionally with unbreakable AES encryption. The ChilkatZip Self-Extractor can safely encrypt the contents of your ZIP file with 128, 192, or 256-bit AES Encryption. To unzip, a user must provide the same password that was used when creating the self-extracting EXE. AES encryption is much stronger than standard ZIP encryption, which is regarded by security experts as being unsecure. Chilkat's streaming compression and encryption technology allows the ChilkatZip Self-Extractor to create an EXE from any size ZIP file. The streaming compression and decryption technology also ensures that it will be possible to unzip the archive on your end-user's computer, even if that computer has very little memory.

	Tweak PDF  License: Freeware
	The initial view of a PDF document can be tweaked. Is it a secret of PDF file? Well, we are not sure about this, and very few pieces of software can tweak PDF files. With the freeware utility Tweak PDF, you are allowed to set the initial view preferences of a PDF document, such as whether to center window of the PDF file when opened, whether to display document title, to fit window, to hide menubar, to hide toolbar, and to hide window UI. When window UI is made hidden, a PDF file is just like a PowerPoint slide zoomed to full screen. You can even set the page mode of a PDF document, such as show PDF files in full screen mode, outlines mode, thumbnail mode, or simply without any special mode. Page Layout also comes as an option for you to tweak. PDF document properties such as title, subject, author, keywords can be modified with Tweak PDF. You can even tweak PDF version from 1.0 to 1.5 for compatibility concerns, and shrink PDF files by setting the compression level and choosing the compression algorithm.
