Software

First of all: even if you are not lucky enough to have a GNU/linux system, you should know that many GNU utilities (gawk, grep, sed, sort, tar, gzip, gcc...) have been ported to DOS: cf. www.gnu.org and DJ delorie software.

1. Data analysis, plotting

AWK. A powerful and simple programming language to parse text files. Terrific for analysing data or scanning databases. It is a standard Unix tool, though I suggest you use the more powerful gawk. Versions for DOS (16 bits and 32 bits) also exist: 16bits version, 32bits version. (more daring wannabe programmers should take a look at Perl)
GNUPLOT: a great tool for plotting math functions or experimental data (error bars available, output in postscript, latex, windows metafile...).
GNU's plotutils. command line plotting tools and library (output in X, editable ps...)
|STAT. A set of very handy data manipulation and statistical analysis programs written by Gary Perlman.

2. Sound utilities

PRAAT. A "research, publication, and productivity tool for phoneticians". This comprehensive speech analysis, synthesis, and manipulation package includes general numerical and statistical stuff, is built on a general-purpose GUI shell for handling objects, and produces publication-quality graphics. By Paul Boersma and David Weenink (U. Amsterdam).
MBROLA. A high-quality speech synthesizer based on concatenation of natural diphones. By Thierry Dutoit.
PIPEWAVE. A set of C programs to perform various operations on sound files.
AFsp. This package provides several audio file utility programs and a library of routines for reading and writing audio files. The programs can be used to compare, copy, filter, resample, and play audio files. There is also a program for generating noise and programs for LPC analysis and synthesis.
SOX. A utility to convert between many different sound file formats (.wav, .aiff, .au, .voc, .snd...).(download it)
COOL EDIT. A simple and efficient sound file editor, for Windows. Perfect for editing, but do not expect to much from the spectral routines.

3. Typesetting, postscript

GHOSTSCRIPT & GHOSTVIEW. These programs allow you to display postscript (.ps) files on your pc, mac, or unix system. With them, it is even possible to print postscript files on many different types of non-postscript printers. The latest versions allow you to print in pdf (not need for Acrobat)!
PSTOEDIT. (Unix) translates PostScript and PDF graphics into other vector formats.
IDRAW. (Unix) A graphical editor that alows to read and edit eps files (restricted postscript)
TEX & LATEX. Simply the best typesetting tools for scientific works. Check out the LaTeX Navigator and the Tex User Group site for more info.
TtH. a TeX to HTML translator

4. Unzipping & decoders

UNZIP. A freeware version of pkunzip, provided by Info-ZIP. I find unzip better (e.g. it restores the directory structure by default). Get here 16-bits DOS version and Win32 version, UNIX version.
GZIP. Gnu zip. performs a better compression than pkzip. However, it compresses only individual files (.gz). It is often used in conjonction with tar. To decode a .tar.gz file:
```
gzip -d file.tar.gz
tar -xfv file.tar
```
Get tar.exe or tar32.exe, and gzip.exe or gzip32.exe.
WINZIP. A shareware for Windows that processes many type of compressed or encoded files: .zip, .hqx, .Z, .gz, .tar, uuencoded,...

5. Misc.

GNU/LINUX. I have been a happy user of both RedHat 5.1 and SuSE 6.3
MHonArc: an Email to HTML converter (requires perl).
HtmlToC: A Table of Contents generator for HTML documents (requires perl).
