Audio (Visual) Programming Frameworks
dublin - Dublin is an object oriented framework to generate events in pd, short for [http://iem.kug.ac.at/pd/ Pure Data], a graphical Computer Music System written by [http://crca.ucsd.edu/~msp/ Miller S. Puckette]. Every object is defined in python and then it interacts with other objects in pure-data. The goal is not only the provide an external python facility to pd but also to give the functionality of a sequencer. As for the user interface, it uses Idle, the Python IDE to edit and run event scripts. [http://seqdublin.sourceforge.net/ >]
pySonic - pySonic is a Python wrapper around the high performance, cross platform [http://www.fmod.org/ FMOD sound library]. You get all the benefits of the FMOD library, but in a Pythonic, object oriented package. [http://pysonic.sourceforge.net/ >]
Loris - Loris is an Open Source C++ class library implementing analysis, manipulation, and synthesis of digitized sounds using the Reassigned Bandwidth-Enhanced Additive Sound Model. Loris supports modified resynthesis and manipulations of the model data, such as time- and frequency-scale modification and sound morphing. Loris includes support and wrapper code for building extension modules for various scripting languages (Python, Tcl, Perl). [http://www.cerlsoundgroup.org/Loris/ >]
Snack - The Snack Sound Toolkit is designed to be used with a scripting language such as Tcl/Tk or Python. Using Snack you can create powerful multi-platform audio applications with just a few lines of code. Snack has commands for basic sound handling, such as playback, recording, file and socket I/O. Snack also provides primitives for sound visualization, e.g. waveforms and spectrograms. It was developed mainly to handle digital recordings of speech, but is just as useful for general audio. Snack has also successfully been applied to other one-dimensional signals. The combination of Snack and a scripting language makes it possible to create sound tools and applications with a minimum of effort. This is due to the rapid development nature of scripting languages. As a bonus you get an application that is cross-platform from start. It is also easy to integrate Snack based applications with existing sound analysis software. [http://www.speech.kth.se/snack/ >]
Pyper - Pyper is a musical development environment. It allows you to write Python scripts that generates music in real-time. Pyper uses QuickTime Musical Instruments for synthesis. [http://www.stanford.edu/~andyszy/pyper/ >]

Csound
Csound / CsoundVST - Csound is a programming language designed and optimized for sound rendering and signal processing. The language consists of over 450 opcodes - the operational codes that the sound designer uses to build "instruments" or patches. Although there are an increasing number of graphical "front-ends" for the language, you typically design and modify your patches using a word processor. Usually, you create two text files - a .orc (orchestra) file containing the "instruments," and a .sco (score) file containing the "notes." In Csound, the complexity of your patches is limited by your knowledge, interest, and need, but never by the language itself. For instance, a 22,050 oscillator additive synthesizer with 1024 stage envelope generators on each is merely a copy-and-paste operation. The same goes for a 1 million voice granular texture! Have you ever dreamed of sounds such as these? Well in Csound you can. And in Csound these dreams can come true! [http://www.csounds.com/ >]
blue - blue is a java program for use with Csound. It's interface is much like a digital multitrack, but differs in that there timelines within timelines (polyObjects). This allows for a compositional organization in time that seems to me to be very intuitive, informative, and flexible. soundObjects are the building blocks within blue's score timeline. soundObjects can be lists of notes, algorithmic generators, python script code, csound instrument definitions, and whatever plugins that are developed for blue. these soundObjects may be text based, but they can be completely GUI based as well. [http://csounds.com/stevenyi/blue/index.html >]
PythonSound - The Python Sound Project aims to develop a productive community around Python, Csound and other synthesis engines as tools for algorithmic and computer assisted composition of electroacoustic music. [http://pythonsound.sourceforge.net/ >]

MIDI Mania
PyPortMidi - PyPortMidi is a Python wrapper for PortMidi. PortMidi is a cross-platform C library for realtime MIDI control. Using PyPortMidi, you can send and receive MIDI data in realtime from Python. Besides using PyPortMidi to communicate to synthesizers and the like, it is possible to use PyPortMidi as a way to send MIDI messages between software packages on the same computer. For example, Using PyPortMidi and MIDI-YOKE on a Windows machine, it is possible to send realtime MIDI messages between programs on the same computer using loopback virtual MIDI ports. [http://web.media.mit.edu/~harrison/pyportmidi.html >]
KeyKit - KeyKit used to be called Keynote. It is a programming language and graphical user interface for MIDI, useful for both algorithmic and realtime musical experimentation. (Note: Although technically not a python product, if you're into MIDI, KeyKit is one of the best free cross-platform tools to use with the python apps on this page. I guarantee you will love it! -- AliaKhouri) . [http://nosuch.com/keykit/ >]
milk - Superceding the older [http://www.quitte.de/nam.html Nam], milk provides Python with classes representing key MIDI sequencer components: MIDI I/O, EventLists, Plugins and a realtime Flow class. The components can be freely interconnected in a fashion very similar to physical MIDI cabling, however the milk event system is not limited to MIDI events alone; you can define your own extensions should the need arise. [http://www.quitte.de/milk.html >]
PMIDI - The PMIDI library allows the generation of short MIDI sequences in Python code.The interface allows a programmer to specify songs, instruments, measures, and notes. Playback is handled by the Windows MIDI stream API so proper playback timing is handled by the OS rather than by client code. The library is especially useful for generating earcons. [http://sourceforge.net/projects/uncassist >]
PyMIDI - The MIDI module provides MIDI input parsers for Python [http://www.hyperreal.org/~est/python/MIDI/ >]

Pymprovisator - Pymprovisator is a program that emulates the program Band in a Box from PG Music. You can think in it like the electronic version of the books+CD from Jamey Aebersold. You set the basic parameters in a song: title, style, key, chords sequence,... and the program will generate a Midi file with the correct accompaniment. [http://pymprovisator.sourceforge.net/ >]
MMA - Musical Midi Accompaniment. If you follow the above link you will find that Pymprovisator is no longer developed due to the fact that there is this similar, but more powerful GPL Python software.[http://mypage.uniserve.com/~bvdp/mma/index.html >]
MP3 stuff
mpgedit - mpgedit is an MPEG 1 layer 1/2/3 (mp3), MPEG 2, and MPEG 2.5 audio file editor that is capable of processing both Constant Bit Rate (CBR) and Variable Bit Rate (VBR) encoded files. mpgedit can cut an input MPEG file into one or more output files, as well as join one or more input MPEG files into a single output file. Since no file decoding / encoding occurs during editing, there is no audio quality loss when editing with mpgedit. A python development toolkit enables Python developers to utilize the core mpgedit API, providing access to mp3 file playback, editing and indexing functionality. [http://www.mpgedit.org/mpgedit/ >]
