The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialized messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols, and more.
Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.
FFTW++ is a C++ header class for the FFTW Fast Fourier Transform library that automates memory allocation, alignment, planning, and wisdom. In 2D and 3D, implicit dealiasing of convolutions substantially reduces memory usage and computation time. Wrappers for C, Python, and Fortran are included.
MBFL is a collection of libraries for the GNU Bash shell. It is an attempt to make GNU Bash a viable solution for medium sized scripts. A set of modules implementing common operations and a script template are offered by this package. The author has used them with success in implementing non-small scripts.
POP-C++ is a comprehensive object-oriented system for developing applications in large distributed computing infrastructures such as Grid, P2P or Clouds. It consists of a programming suite (language, compiler) and a run-time system for running POP-C++ applications. The POP-C++ language is a minimal extension of C++ that implements the parallel object model with the integration of resource requirements into distributed objects. This extension is as close as possible to standard C++ so that programmers can easily learn POP-C++ and so that existing C++ libraries can be parallelized using POP-C++ without too much effort. The POP-C++ run-time is an object-oriented open design that aims at integrating different distributed computing tool kits into an infrastructure for executing requirement-driven object-oriented applications. It uses objects to serve objects: the system provides services for executing remote objects.
SpectMorph allows you to analyze samples of musical instruments and to combine them (morphing). It can be used to construct hybrid sounds, e.g. a sound between a trumpet and a flute, or smooth transitions, e.g. a sound that starts as a trumpet and then gradually changes to a flute. Interpolating between two samples of the same instrument (different attack velocity of a piano) could be interesting. The analysis process decomposes samples into a sum of sine waves (corresponding to the partials present in the signal, or the part of the signal perceived as "tone") and additional noise. SpectMorph is thus based on the research on Spectral Modelling Synthesis.
