Mp3stat is Linux a utility program to compare encoders against an MP3 that was VBR encoded. It outputs a linear graphical bitstream analysis of each MP3 being compared and gives you a breakdown of how many frames of each bitrate are found in the MP3. It basically allows you to see how encoders treat areas in the same MP3s differently and lets users discover some of the bitrate effects of different quality levels of the same encoder. Mp3stat also supports Oggs.

Version 2.5.10 of mp3stat is shipping as July 2004.

PicoZip is an award winning file compression utility that runs on all 32-bit Windows platforms such as Windows 95, 98, ME, NT4, 2000 and XP. It is extremely easy to use, yet contains many advanced features that helps you create or unzip ZIP files, as well as most other popular archive formats like RAR, ACE, LHA, JAR, etc.

PicoZip 3.0 shipping as of July, 2004.

DataCompression.info user Derek P. had this to say: This is one of the best Zip Utilities out there! The Batch Testing of Archives tool is fast and accurate!!! Other Zip Utility Makers need to take notes!.

DynaZIP offers just about everything you’d want to work with Zip files in a Win32 environment.

DataCompression.info user Mike L. had this to say: Creates huge output executables. Features contained in multiple packages are contained in a single package in comparable products. Pricing is very steep compared to comparable products.

OggPlay is an Ogg vorbis audio player for smartphones. I started working on this project in early April 2003. The 1st version for the SonyEriccson P800 was released end of April. Many people have contributed localized versions, new skins, documentation, and are helping with porting the application to other phones since then. OggPlay has become a true open source project

Unlike some other compressor comparison sites, I won’t be looking for a compressor offering for the last bit of compression. Instead I’ll try to find the most practical compressor out there.

This site compares compressors on the basis of compression ratios only. Speed is not an issue.

I’m pleased to announce with my co-authors availability of a preprint on our new algorithm to estimate the Shannon entropy rate (bits/symbol) or (bits/sec) of an observed sequence of low-alphabet symbols. It uses the Context-Tree-Weighting universal compression method, but doesnot use the compression ratio directly as an entropy estimator but as a scaffold for a Bayesian estimate. The result is significantly lower bias.
