除了上面提到的壓縮方法，你也可以調用VB的工具MakeCab.exe（在VB5\setupkit\kitfil32或VB98\Wizards\PDWizard目錄下）生成.cab文件。先構造一個Directive 文件(*.ddf)，然后使用Shell命令調用MakeCAB /f excel.ddf就可以生成*.cab文件。關于Directive 文件的格式，可以參考MSDN Library中的《MakeCAB: A COMPRESSION and Disk Layout Tool》一文。

The Audio File Library provides a uniform programming interface to standard digital audio file formats. This library allows the processing of audio data to and from audio files of many common formats (currently AIFF, AIFF-C, WAVE, NeXT/Sun .snd/.au, IRCAM, AVR, Amiga IFF/8SVX, and NIST SPHERE). The library also supports COMPRESSION (currently G.711 mu-law and A-law and IMA and MS ADPCM) as well as PCM formats of all flavors (signed and unsigned integer, single- and double-precision floating point).

DIGITAL IMAGERY is pervasive in our world today. Consequently, standards for the efficient representation and interchange of digital images are essential. To date, some of the most successful still image COMPRESSION standards have resulted from the ongoing work of the Joint Photographic Experts Group (JPEG). This group operates under the auspices of Joint Technical Committee 1, Subcommittee 29, Working Group 1 (JTC 1/SC 29/WG 1), a collaborative effort between the International Organization for Standardization (ISO) and International Telecommunication Union Standardization Sector (ITUT). Both the JPEG [1–3] and JPEG-LS [4–6] standards were born from the work of the JPEG committee. For the last few years, the JPEG committee has been working towards the establishment of a new standard known as JPEG 2000 (i.e., ISO/IEC 15444). The fruits of these labors are now coming to bear, as JPEG-2000 Part 1 (i.e., ISO/IEC 15444-1 [7]) has recently been approved as a new international standard.

This file contains a new and improved version of the Huffman coder, (June 29. 2001). The name is Huff06.m. There are also some additional files which are helpful when using Matlab for data COMPRESSION: quantizer, different variants of run-length-encoding and end-of-block coding in Mat2Vec, and a program which do JPEG-like entropy coding. A complete COMPRESSION example is shown in TestMat2Vec.m. This file is all you need for Huffman coding in MatLab.

這是06年4月剛剛完成的程序，從opencore.org下載而來。用vhdl語言描寫，以及matlab仿真，testbench，以及在xinlinx上的綜合。 The MDCT core is two dimensional discrete cosine transform implementation designed for use in COMPRESSION systems like JPEG. Architecture is based on parallel distributed arithmetic with butterfly computation.

Wavelets have widely been used in many signal and image processing applications. In this paper, a new serial-parallel architecture for wavelet-based image COMPRESSION is introduced. It is based on a 4-tap wavelet transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is done using a tree of carry save adders to ensure the high speed processing required for many applications. The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis reveals that the proposed architecture, implemented using current VLSI technologies, can process a video stream in real time.
