In his work on the information content of English text in 1951, Shannon described a method of recoding the input text, a technique which has apparently lain dormant for the ensuing 45 years. Whereas traditional compressors exploit symbol frequencies and symbol contexts, Shannon’s method adds […]

Ogg Vorbis is a fully Open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. This places Vorbis in the same competetive class as audio representations such as MPEG-4 (AAC), and similar to, but higher performance […]

Source code and demo projects from Ciprian Miclaus. Ciprian said he created this because the only other available port for CE did not include source.
DCL reader Mike P. said Very good … especially that I found on the same site a port of libbzip2 for WinCE. Excellent … exactly what my project needed.

Al Williams wrote an excellent article on using the Info-Zip DLLs to manipulate Zip files. There are lots of commercial libraries that let you access Zip files, but your choices in free software are few and far between. So if you need a free solution, Al’s article is a must-read. Many thanks to Al for […]

Fed up with limited compression performance of Stacker, PKZIP, UC2, ZOO, ARJ and LHA? CRUSH will usually give 5%-50% improved compression over any other DOS compression tool, and yet allows the user to continue using the archiver already in use. CRUSH is fast and the ideal choice for users keen to save disk space. I […]
