Projects and Research
The following partially outlines some of the work I'm doing and have done in recent years.
I have been working on the SoundWIRE Research Group at CCRMA, Stanford University for the last couple of years as part of my PhD studies.
We are concerned with the use of Internet networks as an extension to computer music performance, composition and research. Research areas include:
» Professional-Quality Multi-Channel Audio Streaming
» Internet Physical Models and Virtual Acoustics
» Sonification of Network Reliability
» Human factor (psychoacoustics) in Network Performance
» Internet/Computer/Acoustic Music Performance Practice
We are exploring ways not only of minimizing network delays so as to allow distant players to perform together live, but also to employ delay as a structural musical element that may, for example, give rise to works that are heard differentially on either side of the internet divide.
The MvW group deals with the intersections between musical performance/composition and the use of virtual environments as controlling and performative spaces. I've been working mainly with Robert Hamilton on performances that involve virtual world musicians and acoustic performers, in particular with the Stanford Humanities Lab and computer science project Sirikata.
Chris Chafe and I have been developing JackTrip, a Linux and Mac OS X-based system used for multi-machine network performance over the Internet. It supports any number of channels (as many as the computer/network can handle) of bidirectional, high quality, uncompressed audio signal steaming.
JackTrip has been widely used in network performances concerts. It has recently been selected as the software of choice for the European CoMeDia project.
We are always looking for developers so if you're interested, please contact me!
We've been doing a lot of music in the network in the last few years. Or, as Chris Chafe put it, "We're getting to a point where it feels strange sometime to play in the same room".
Some highlight include performance with Pauline Oliveros, a highly produced and press-covered concert with China (picture), performances in conferences like ICMC, Siggraph and ICAD.
The Net vs. Net Collective, a collective of musicians that Alain Renaud and I founded, performs regularly between the US and Europe.
A team at CCRMA worked in this project to create a masker to use in office and other types of spaces. This was a joint project with Yamaha's Center for Advanced Sound Technologies Innovative Technology Group.
The aim of a solution is to carpet a living or working area unobtrusively in a way that enhances privacy and minimizes unwanted intruding sound. Synthetic sound masking has been important in audio compression, but seems also to be gaining popularity for ambient sound applications.
During my undergrad studies (and my previous life) in Structural Engineering I worked for some time in a dynamic structural analysis toolbook for MATLAB called SAT-Lab. I programmed and tested several of the elements for non-linear seismic analysis of structures.
My undergrad dissertation details some of this work.
