sloop.splitter is a realtime sound effect program. It samples sounds from any source and dissects them. It searches for waveforms and repeats them from one repetition to thousands. So, it generates synthetic sounds from natural ones. The waveforms are never deformed, only repeated, so always natural waveforms are played, but in a more or less synthetic way. The number of repetitions constantly changes from one (the identical sound) to thousands and back. It tries to show the transition between the synthetic and the natural.
Songwrite is a tablature editor. It supports many string instruments in addition to traditional staff notation. You can edit tablature (guitar, bass, banjo, etc.) and staff notation, add lyrics, create your own songbook, play your partitions, print your partitions and your songs, automatically convert staff notation to tablature and vice-versa, export songs to many formats (PDF, MIDI, ASCII tablature, GNU Lilypond, LaTeX, PostScript, etc.), and import Guitar Pro 3/4 files (experimental).
PyMP3Cut is a Python command line tool designed to cut huge (> 100MB) MP3 files at high speed without requiring the extra disk space and processing time usually needed by visual audio editing tools, which convert the MP3 format to more easily manageable formats like WAV before doing anything. It reads and cuts simultaneously according to the autodetected MP3 frame rate and a timeline passed as a command line argument. It doesn't currently deal with Variable Bit Rate (VBR) MP3 files, though.
Autocomp is an accompaniment generator for Perl and Csound. It takes as input a text file containing chord changes, plus time signature and bpm information, and outputs a Csound .sco file containing a simple arrangement of those changes. A sample Csound .orc file containing a bass instrument, a selection of keyboard instruments, and a small sample-based drumkit is provided.
Audiality is a highly scalable and portable audio engine and synthesizer. MIDI files are used in combination with scripting and modular synthesis, to minimize file sizes and maximize flexibility. Audiality can be used as a music and sound effects player in multimedia productions, or as a realtime MIDI synthesizer.
Csound is a powerful and yet easy to use musical synthesis package. Csound was constructed in the tradition of so-called music-N languages, among which the best-known is Music V. It consists of an orchestra- and score-driven executable, written in C for portability. Since Csound is a computational language, it is highly flexible and efficient; complexity is gained only at the expense of computation power. Basically, Csound reads some files and creates the result as a sound file on disk or, on faster machines, in real time through a DAC.
Pysco is a neat utility for CSound. It generates CSound note events and saves to a score file, with unlimited separate output time-streams ("tracks"), unlimited simultaneous different tempos (each track can have its own tempo, including independent accelerandos and ritards), unlimited named "chunks" of events, and many more functions to provid automatic time updating so that the user doesn't have to count beats all the time. It also selects ranges of musical chunks by beat value.
WaveSurfer is a sound visualization/manipulation tool for novice and advanced users, with a simple and intuitive user interface. It can be adapted to different tasks, such as speech research and education, speech/sound analysis, and sound annotation/transcription. You can also make more advanced/specialized applications by extending it with custom plugins or embed WaveSurfer components in other applications. Its flexible interface handles many different file formats, and it runs on many flavors of Windows and Unix. It also supports encoding and Unicode with unlimited file size, and more.
