Cecilia is an audio signal processing environment. Cecilia lets you create your own GUI (grapher, sliders, toggles, popup menus) using a simple syntax. Cecilia comes with many original builtin modules for sound effects and synthesis.

Previously written in tcl/tk, Cecilia (version 4, deprecated) was entirely rewritten in Python/wxPython and uses the Csound API for communicating between the interface and the audio engine. Version 4.2 is the final release of version 4.

Cecilia5 now uses the pyo audio engine created for the Python programming language. pyo allows a much more powerfull integration of the audio engine to the graphical interface. Since it's a standard python module, there is no need to use an API to communicate with the interface.

For those intrepid live-coding adventurers that are looking for that more immersive connection with your Overtone musical processes TouchOSC is an excellent tool to play with:

It's super easy to use it to control and trigger synths and other functionality you might build on top of Overtone and it's an excellent way to start playing around and exploring with parameters whilst you're just starting and finding your way around the vast library of ugens.

Let's look how we can get TouchOSC talking to Overtone.

NodeBox for OpenGL is a free, cross-platform library for generating 2D animations with Python programming code. It is built on Pyglet and adopts the drawing API from NodeBox for Mac OS X (http://nodebox.net). It has built-in support for paths, layers, motion tweening, hardware-accelerated image effects, simple physics and interactivity.

The DSP Dimension started out as a platform for online courses and tutorials on Digital Signal Processing in 1999 as part of Stephan Bernsee’s lectures on advanced audio DSP held at various institutions around Germany. The DSP Dimension quickly became a standard resource for specialized DSP topics like time stretching and pitch shifting and is part of engineering classes at several universities across Europe as well as a frequently featured content in many popular magazines. Today Stephan and his team are providing consulting and development services to the audio signal processing market and are developing applications marketed through their partners around the world.

liblo is an implementation of the Open Sound Control protocol for POSIX systems, started by Steve Harris. liblo is written in C and works on many platforms including Linux, Mac OS X and Windows. It has support for all the OSC types, threaded servers, dispatching and timestamped delivery of bundles. It is released under the GNU General Public Licence.

There are many implementations of OSC in the form of C language libraries. How do you choose which one to use for your project?

Open Sound Control (OSC) is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is optimized for modern networking technology. Bringing the benefits of modern networking technology to the world of electronic musical instruments, OSC's advantages include interoperability, accuracy, flexibility, and enhanced organization and documentation.

PXDK is a GUI cross-platform development kit, designed specifically for audio plug-ins. It is the perfect tool for making stable, professional plug-ins for multiple targets, without sacrificing any advanced features.
PXDK is an object-oriented system, using C++. Yes, this means you can produce Cocoa plug-ins on 64-bit OSX, without even reading 1 single line of Obj-C. This is the power of PXDK. Instead of using your energy on ever-changing APIs, you can focus on the value which the end-user can appreciate.

PXDK is available for VST 2.4, VST 3, AU, RTAS and TDM, Windows and OSX, 32- and 64-bit, Carbon and Cocoa. And for every single one of those platforms, your code is the same (although, for TDM you would obviously need to write extra DSP code).

Mercurial is a free, distributed source control management tool. It efficiently handles projects of any size and offers an easy and intuitive interface.

Mercurial is a modern, open source, distributed version control system, and a compelling upgrade from older systems like Subversion. In this user-friendly, six-part tutorial, Joel Spolsky teaches you the key concepts.

Disco is an implementation of the Map-Reduce framework for distributed computing. As the original framework, which was publicized by Google, Disco supports parallel computations over large data sets on unreliable cluster of computers. This makes it a perfect tool for analyzing and processing large datasets without having to bother about difficult technical questions related to distributed computing, such as communication protocols, load balancing, locking, job scheduling or fault tolerance, which are taken care by Disco.

TCP, UDP, and SCTP all use port numbers to identify the logical communications between hosts. The combination of a port and IP address identifies a TCP/UDP/SCTP Endpoint, and the endpoint pairs on either end of a "connection" make up a TCP/UDP/SCTP Conversation.

This book is a gentle introduction to digital filters, including mathematical theory, illustrative examples, some audio applications, and useful software starting points. The theory treatment begins at the high-school level, and covers fundamental concepts in linear systems theory and digital filter analysis. Various "small" digital filters are analyzed as examples, particularly those commonly used in audio applications. Matlab programming examples are emphasized for illustrating the use and development of digital filters in practice.

This book was written for my introductory course in digital audio signal processing, which I have given at the Center for Computer Research in Music and Acoustics (CCRMA) since 1984. The course was created primarily as a first course in digital signal processing for entering Music Ph.D. students in the Computer Based Music Theory and Acoustics program. Due to the nature of CCRMA research, this book will emphasize audio and music applications, although the material on the subject of digital filters itself is not specific to audio or music.

This intro provides a ``getting started'' guide for the Synthesis Tool Kit (STK) [1,2] under Linux [5] and Mac OS X. This guide is aimed at developers of STK software, as opposed to mere users. As a result, a couple of modifications will be introduced to facilitate software development (i.e., debugging C++ code). It is also assumed that some variant of UNIX is the resident operating system. It is assumed that the reader already has some familiarity with programming in C and ideally also C++

FAUST is a compiled language for real-time audio signal processing.
The name FAUST stands for Functional AUdio STream. Its programming model combines two approaches : functional programming and block diagram composition. You can think of FAUST as a structured block diagram language with a textual syntax.

The Linux Audio Developers (LAD) list is dedicated to the development of audio applications and infrastructure for the Linux Operating System. With its proven stability and scalability, it is a perfect foundation for the handling and processing of large amounts of audio data.

Our goal is to encourage widespread code re-use and cooperation, and to provide a common forum for all audio related software projects and an exchange point for a number of other special-interest mailing lists.
