Computer Algebra System written in Common Lisp
Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. For example, Maxima solves x^2-r*x-s^2-r*s=0 giving the symbolic results [x=r+s, x=-s]. Maxima can calculate with exact integers and fractions, native floating-point and high-precision big floats. Maxima has user-friendly front-ends, an on-line manual, plotting commands, and numerical libraries. Users can write programs in its native programming language, and many have contributed useful packages in a variety of areas over the decades. Maxima is GPL-licensed and largely written in Common Lisp. Executables can be downloaded for Windows, Mac, Linux, and Android; source code is also available. An active community maintains and extends the system. Maxima is widely used: annual direct downloads exceed 300,000. Many other users receive it through secondary distribution.

A loudspeaker phase linearization, EQ and filtering tool
rePhase is a FIR generation tool for building fully linear-phase active crossovers with arbitrary slopes. It also let you manually compensate for the phase shifts of your loudspeakers and existing crossovers, be it active or passive. Once generated, the FIR can be applied using any hardware (openDRC, miniSHARC, Najda, ...) or software (foobar, convolver, JRiver, ...), stereo or multi-way convolution engine. Donate: rePhase is free software. If you like it you can support its development with a donation. - paypal: https://goo.gl/v44mmD Tutorials: - miniDSP application note: http://goo.gl/9krGT8 - Pat Brown's prosoundweb article: http://goo.gl/gJG1Of - mwillems' tutorial: http://goo.gl/oKgmhx - Jimmy Thomas' tutorial (in French): http://goo.gl/7kBt7Q Support: - diyaudio forum thread: http://goo.gl/KA5ilz - miniDSP forum section: http://goo.gl/U78IXD - direct email: http://scr.im/rePhase rePhase - Copyright © 2012-2016 Thomas Drugeon

A program for fitting structural models to small angle scattering data
SASfit has been written for analyzing and plotting small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, Porod constant. Furthermore it can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of (global) parameters. This last option is especially important in contrast variation experiments or measurements with polarised neutrons. The global fit helps to determine fit parameters unambiguously which by analysing a single curve would be otherwise strongly correlated.

YouTube Downloader - Cross Platform
YouTube-DL-PyTK (formerly known as YouTube-DL-GTK) is just a graphical launcher for the popular youtube downloader youtube-dl . Its purpose is simple; to facilitate the downloading of non-copyright-protected videos from certain internet websites including YouTube. It is written in Python, so it should run on Windows and Linux systems alike. I don't have access to an Apple computer to test it on OSX, but it might also work on that platform. It includes the Windows and Unix version of youtube-dl, so there's no need for you to go download it yourself for this to work. This little project packages everything you need to start using it in one package, and all the appropriate licensing information is located in the archive. If you have ran the installer on Windows, you can find the source code and all of the documentation in the installation folder.
