360 Degree Sound

Wave Field Synthesis 32-channel Loudspeaker Array

gurley_3d

The new Wave Field Synthesis (WFS) loudspeaker array will be installed in the Gurley Lab this week. This hybrid virtualization system will provide from a highly spatial accurate (wavefront synthesis up to 1.1 kHz) frontal array coupled to a 2D HD video projection system. Room modeling will be accomplished in real-time using a custom convolver coupled to a surround speaker array. The WFS system will spatialize up to 16 virtual sources in a modeled room with up to second-order reflections. This reproduction system is similar to that used in my Master’s research, but with half the spacing between speakers in the frontal array (9.5 cm). The WFS system will be used for real-time telematic musical performances, research on audio-visual interactions and multi-modal distance perception.

Performance at RPI for NY Times

A NY Times reporter is coming to RPI on Tuesday, August 5th to tour the Ca3rl Lab and EMPAC Facility. During the visit Jonas Braasch, myself, and Pauline Oliveros will be performing telematically with Chris Chafe at Stanford University. The visit will focus on our research into live improvised music over the internet. The Times will be also visiting the Workspace Unlimited installation as well as other projects at EMPAC.

Workspace Unlimited

I have been working with the group Workspace Unlimited to develop a 360 Degree sound spatialization patch to auralize there visual work. Using an adaptation of the ViMiC Wooster environment, we created a virtual surround panning algorithm which places an array of virtual speakers outside the array of virtual microphones. The virtual microphones pick up the loudspeaker signals and present them ins 360 degrees over the 32 loudspeakers. Provisions for room modeling are also added to generate a virtual recording space for the virtual loudspeakers. The patch is done, but we are having several clocking/jitter issues that will most likely be ironed out monday.

Summer Work at EMPAC

I haven’t updated this site in a while and I will try to be better at this from now on. I’ll start off with a quick summary of what I have done since 2/3/08 when last i’ve last posted. It’s summer now and I have been working with the Electronic Music Foundation performing IT, acoustical design, and LEED tasks for the construction of their new headquarters in Albany, NY. This has been a fun a challenging project and should turn out quite nice when it is planned to be open (Sept 1, 08). I have also been working with EMPAC, RPI doing Max/MSP programming for a performance to be planned for the fall of this year. I can’t say much about it other than it calls for lots of speakers, computing power and high-resolution projectors. My ACTA Acustica-united with Acustica paper has been accepted with revisions which I am currently working on and plan on resubmitting in a week or two. I have a JASA paper in the final stages of draft form and I am also working on my Dissertation proposal, planned for September of this year. It’s been a busy last couple of months and hopefully all of my current projects will turn out well.
