Note: This video was produced with binaural sound. Please listen with headphones to experience the binaural effect.

In this “duet” I am using the Korg Monotribe to join in with the laundromat ambience as if it were a conscious participant in an improvisational ensemble. The activity in the space produced oscillations that caused sound waves forming drones and rhythmic patterns. I responded with basic oscillators like pulse, saw, or triangle waves. I manipulated the filter, LFO and pitch to create more complex textures that alternately blend and contrast with the ambient sound.

The ambience was recorded with a set of binaural microphones. When wearing stereo headphones the playback of a binaural recording accurately positions the direction of each sound for the listener, immersing them in the spatial soundscape. In contrast the synthesis was recorded in mono, without additional processing. This simulates a process called phonomnesis, or imagined sound, by placing the signal in the center of the listeners sound-space.

Motherboard.tv has an article on what is probably the world’s largest synthesizer (let’s not forget T.O.N.T.O) created by Joe Paradiso over about twelve years starting in 1974. It has recently been installed at MIT. What is amazing is that you can listen to long audio files of patches that Joe creates every couple of weeks, or (now for the really crazy part) visit an online interface to literally control the synth remotely with other users doing the same thing!

This is not my usual kind of topic, but I just came across an exciting new development. Sony has introduced the Xperia Sola with what they call floating touch capability. The screen on the device detects the presence of a finger up to 20mm away allowing for mouse-like hovering behaviors. What this means for me is that it would be an easy matter to create a velocity sensitive touch keyboard or set of pads on a device with this feature. Simply measure the time between entering the field and actually touching the device and then apply the number to the amplitude, or any other attribute of the sound. There is a significant amount of potential for expression with this technology. I would love to see this on a tablet and develop an instrument it. How would you like to see floating touch (or something like it) used for music applications?

I have recently become aware of an excellent sound design and music event series held at the Bleicher Gallery in Santa Monica, CA. The series is titled The Art of Music and on March 25, 2012 they will feature a showcase by one of my favorite sound artists, Diego Stocco, as well as a performance by Nat Evans. The purpose of the series is to present “…an oasis in Hollywood for criminally overlooked music, giving media professionals a unique chance to discover new resources, discuss upcoming projects and forge new creative partnerships.” Checkout the details at artofmusicla.com.

Recently I participated in a performance with a collective of musicians called Coloring Time. The show took place on Saturday, January 28, 2012 at the History Theatre in downtown St. Paul, Minnesota and was sponsored by McNally Smith School of Music. Performers include: Crescent Moon (Kill the Vultures), Kristoff Krane, Chastity Brown, Aby Wolf, Peter Pisano (Peterwolfcrier), Joe Horton (No Bird Sing), Michelle Kinney and Melissa Mathews (Mississippi Peace), Chris Thomson, Bobby Mullrennan (No Bird Sing), Casey O’Brien (Face Candy), John Keston (Ostracon, DKO), Graham O’Brien (Mississippi Peace, No Bird Sing), and many others. This video is from the last six minutes of the performance. Apparently there’s much more to come. If it’s as lovely as this segment I will share it here when it shows up. Enjoy!

The first ever Eyeo Festival was last June and the second iteration looks to be just as amazing as the last. Here’s a video of a presentation that I gave at Eyeo last year on using digital imagery to generate sound. I also have the HTML5 slideshow available (use the left and right arrow keys to navigate). A big thanks goes out to Dave Schroeder for creating Eyeo and sharing these videos.

My trio, DKO performs Tuesday, February 21st @ Acadia Cafe. 9pm/all ages/free. More for information about DKO visit AudioCookBook posts tagged with DKO, or checkout our tumblr page.

Midnight Playground is an interactive, kinetic, installation by Peng Wu, Jack Pavlik, John Keston, and Analaura Juarez. Peng initiated and directed the idea, Jack built the jump rope robot, and Annalaura helped refine the concept and promote the piece. My role was to produce the music and track it to the still images that Peng had selected. I ended up making a one hour video with thirty minutes of the image from the moon followed by a four second transition into another thirty minutes with an image of Mars. To produce the sound I gave Peng a list of audio excerpts that had all been previously posted on AudioCookbook in One Synthesizer Sound Every Day. He picked the two that he thought would work the best and I went back to my original recordings and processed them specifically for the piece by adding some reverb and delay to enhance the spacial properties of the music. The piece will be on display in Gallery 148 at the Minneapolis College of Art and Design through January 29, 2012.
