linuxDSP aims to provide high quality 'plugin' audio processing software for PCs running linux.

The beagle synth will be a full featured MIDI synth based around the beagleboard. This project is to be a learning experience with the intention of exploring using DSP for music synthesis.

iRedux is a Sound & Music Re-Appropriation and Re-Interpretation System for Gallery Installation & Live Performance. iRedux aims to generate discourse surrounding issues fundamental to music download-culture – those of ownership and authorship. Through a combination of pre-set digital signal processes and aleatoric remixing, iRedux generates unique and original music, utilising the compositions of other composers. iRedux will re-appropriate an album, chewing up old music and giving birth to new sounds – using the original album as inspiration whilst simultaneously corrupting and destroying it.

The Echo Nest Remix API lets you manipulate music and video from the web. We've done the following: rearranged the syllables of a vocal line, walkenized and cowbellized hundreds of thousands of songs in a week, mixed up the hits of a drum beat and synced it to another loop, beat matched two songs, split apart DJ mixes by their individual tracks, made new kinds of music, synced a video to a song, transitioned between two covers of the same song, made a cat play piano. We're making this available as an open source SDK for Python that can currently be easily installed for Mac OS X and Linux. It accesses the Echo Nest Analyze API at http://developer.echonest.com seamlessly through a web services interface and parses the results. You'll need an Echo Nest API key to use this SDK.

PWGL is a free cross-platform visual language based on Common Lisp, CLOS and OpenGL, specialized in computer aided composition and sound synthesis. It integrates several programming paradigms (functional, object-oriented, constraint-based) with high-level visual representation of data and it can be used to solve a wide range of musical problems.

This tutorial is designed for self-study, principally for composers. It begins with explanations of basic programming and acoustic principles then gradually builds up to the most advanced electronic music processing techniques. The book’s teaching approach is focused primarily on hearing, which we consider a faster and more enjoyable way to absorb new concepts than through abstract formulas.

The Open Prosthetics Project is producing useful innovations in the field of prosthetics and freely sharing the designs. This project is an open source collaboration between users, designers and funders with the goal of making our creations available for anyone to use and build upon

Ducking', or lowering the audioscape volume, can create greater engagement for listeners, and Day 1's Quarles explains how it's done in this fascinating game audio feature

WaveScope is a system for developing distributed, high-rate applications that need to process streams of data from various sources (e.g., sensors) using a combination of signal processing and database (event stream processing) operations. The execution environment for these applications ranges from embedded sensor nodes to multicore/multiprocessor servers.
