FreedomAudio is a free Open Source package that lets you stream MP3 and Ogg Vorbis files from your web site. It renders audio using a small Java plugin. The nice part about using a plugin is that you only have to download an install this once. Freedom Audio also now supports a plugin-free mode, but apparently this results in reduced fidelity.

Version 1.08 Build 20 shipped in April, 2003.

From the web site: gtranscode is a GTK+ GUI (graphical use interface) front-end for transcode in order to make this powerful tool easier to use. transcode is a powerful video and audio processing tool that can read in just about any format of video and/or audio and convert to just as many different formats. In addition to transcode’s extremely flexible modular concept for reading/writing different formats and codecs, it can apply filters, do re-sampling, resizing, cropping, and more.

Version 0.1.5 is shipping in April, 2003.

Reader Erin S. raves about gtranscode: Excellent usability, easy to install, and not only supports all the major functions of transcode, but anything it doesn’t support, you can add manually…the most versatile transcode yet!

From the web site:crip is a terminal-based ripper/encoder/tagger tool for creating Ogg Vorbis/FLAC/MP3 files under UNIX/Linux. It is well-suited for someone seeking to make a lot of files from CDs and have them all properly labeled and professional-quality. One thing to note is that the author of this free package has removed MP3 support, and limits you to Ogg Vorbis or FLAC for encoding.

Version 3.4 is shipping as of April, 2003.

This appears to be a tool that is designed to aid you in the process of digitizing your LPs and cassettes to your PC. It will export to MP3 format, which explains its presence here.

This program appears to be a decompressor only - it lets you look at the contents of a Zip file, but doesn’t give you a way to manipulate the contents. It offers the ability to preview files from inside the Zip file, and has a mysterious feature that I don’t understand:

ZipForward™ can burn your package to an Application (.EXE) format. This means that anyone with a Windows computer can run and extract your package, just by double-clicking the icon. From then on they can use the package you gave them to send to their friends, and their friends, and so on.

ZipForward 1.1 is shipping as of April, 2003.

This is another German preprint of Jürgen Abel describing the principles of the Burrows-Wheeler Compression Algorithm. An
implementation of a BWT based compressor with a compression rate of 2.25 bps on the Calgary Corpus is presented. The paper will be

(Gesellschaft für Informatik eV.)

ezMPEG is an easy-to-use and easy-to-understand MPEG1 video encoder API. The author says I started this project because I wanted to know how MPEG works and the best way to learn it is to implement my own encoder. So I downloaded the ISO specs and began to read and code. My implementation doesn’t have the goal to be better than all the others. The goal is to have a simple, portable and esay to understand code for all the people (and for me) who wants to know how a MPEG1 video encoder works.

Version 0.1b of this library shipped in April, 2003. It is still listed as being in Alpha status, so temper your expectations for right now.

LuraDocument represents an innovative compression software custom-tailored to the compression of scanned color documents composed of both images and text. The documents are partitioned into pure picture and pure text segments through the use of its state-of-the-art segmentation algorithm. Each of these segments is then compressed using an algorithm optimized for this type of data. As a result, scanned color documents can be stored at extremely high quality despite small file sizes. LuraDocument is capable of reaching compression rates of 1:150 to 1:500 while still preserving full readability of the text and excellent quality of the pictures. This makes LuraDocument far superior to even the wide spread PDF format.
