HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone's headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation. HiJack has been tested with the iPhone 3G/3GS/4G, iPod Touch, and iPad devices.

With WebRTC, we are open sourcing the voice and video engine technologies from our acquisition of GIPS, giving developers access to state of the art signal processing technology, under a royalty free BSD style license. This will allow developers to create voice and video chat applications via simple HTML and JavaScript APIs.

A few years ago, I implemented an S/PDIF encoder object for the Parallax Propeller. When I first wrote this object, I wrote only a very terse blog post on the subject. I rather like the simplicity and effectiveness of this project, so I thought I’d write a more detailed explanation for anyone who’s curious about the gritty details.

This page will show you how to turn a $199.95 (Canadian – Suggested Retail) pair of Sennheiser HD 555 headphones into a pair of Sennheiser HD 595‘s that cost $349.95. And all you need is a screwdriver.

"SuperCollider is an environment and programming language for real time audio synthesis and algorithmic composition. It provides an interpreted object-oriented language which functions as a network client to a state of the art, realtime sound synthesis server."

"The Prism is, quite simply, the best laser guitar on the Internet. At least I think so. I hope that you take these instructions and not only make your own, but improve on my design!

I suppose I should clarify what the Prism is: It's a bit like a guitar with some synthesizer mashed in. It has aspects of a theremin and a laser harp thrown in to boot. In short, it's not like anything else, and you can use it to make some really neat sounds. Anything from cold Sine and harsh square waves to heavily distorted noise.

At its heart the Prism features a VCO (Voltage Controlled Oscillator), based around the very shiny XR2206 monolithic function generator. The octave range is selected by blocking one of four laser "strings," and the pitch is controlled by the position of the musician's hand on the fretboard. The musician has the option of selecting a sine, triangle or square wave. The sine and triangle waves can be skewed using a separate Skew control."

Last weekend I open-sourced a small side project consisting of a JavaScript library that generates MIDI in a simple manner.

"Mixxx is free, open source DJ software that gives you everything you need to perform live mixes."

This particular audibilization is just one of many ways to generate sound from running sorting algorithms. Here on every comparison of two numbers (elements) I play (mixing) sin waves with frequencies modulated by values of these numbers. There are quite a few parameters that may drastically change resulting sound - I just chose parameteres that imo felt best.

After making this video I found that someone already tried to audibilize sorting algorithms:

And someone in comments metions similar attempt on different aproches to Towers of Hanoi problem in 1982; there was also attempt on trying to hear minimax search in chess engine in 2009: http://www.krazydad.com/blog/2009/05/...

"This is a program for stretching the audio. It is suitable only for extreme sound stretching of the audio (like 50x) and for applying special effects by "spectral smoothing" the sounds. It can transform any sound/music to a texture. The program is Open-Source and it's released under the version 2 of the General Public License. You can download the source code for Linux or the Windows binaries."

StartupSound.prefPane is the software which controls the volume of the startup sound of your Macintosh computer. StartupSound.prefPane mute the startup sound without changing the output volume setting. And StartupSound.prefPane limits the startup volume so that it may not become loud even if you make the output volume louder. To set up the startup volume, you select the "Startup Sound" pane added to the "System Preferences."

"Liquidsoap is the audio stream generator of the Savonet project, notably used for generating the stream of netradios. It has tons of features, it's free and it's open-source! Liquidsoap lets you to describe your streams in a powerful and flexible way. Allowing arbitrarily deep-nested composition of streams, it gives you more power than you need for creating an original netradio. But liquidsoap is still very light and easy to use, in the Unix tradition of simple strong components working together."

Also supports video by now.

At the Audio MC at the Linux Plumbers Conference one thing became very clear: it is very difficult for programmers to figure out which audio API to use for which purpose and which API not to use when doing audio programming on Linux. So here's my try to guide you through this jungle:

JUCE (Jules' Utility Class Extensions) is an all-encompassing C++ class library for developing cross-platform applications.
