HTML5 Audio Visualization for Illuminator Console

Recently I have been investigating some of the new capabilities of web browsers that support HTML5 and include JavaScript enabled audio APIs. This video excerpt above is a screen capture of an audio visualization that I produced with Processing.js, HTML5 and the Audio Data API that’s built into Firefox 4 Beta. The audio analysis is based on code from this example by Corbin Brook.

Circles are drawn that vary in size dynamically based on the amplitude of the music. The track is Illuminator Console by Ostraka (John Keston) from the album Precambrian Resonance on Unearthed Music. This application will only work in Firefox 4 Beta. To view the full visualization visit the following link:

What is Your Favorite Poly Synth?

For the last few of years I have been craving the sound of polyphonic, analogue synthesizers. Although I’ve got a collection of aging monophonic (and one duophonic) beasts, I haven’t owned an analogue polyphonic slab since I had an Oberhiem Matrix-6. Before that, it was one of my first instruments, the Korg Poly-800. Both of these synths sound great, but I can’t forget the frustration I experienced with their lack of tactile potentiometers. Although I wish I still had it now, the membrane buttons on the Matrix-6 were especially annoying.

Recently I joined a trio name DGK (Jon Davis, Tim Glenn, and John Keston) that I think would benefit from a versatile polyphonic analogue instrument on top of my Rhodes electric piano. I have few rigs in mind (insert vintage Korg, Roland, or Akai), but I’m looking for a good knob to dollar ratio (more knobs and less dollars). What are your favorite poly-synths and why? Ever get rid of something you wish you hadn’t? Or have you been assimilated by the latest software synths?

Electric Independence: Oneohtrix Point Never

I just checked out the latest episode of Motherboard‘s series, Electric Independence, on synthesist Oneohtrix Point Never. I have no argument against his return to the rich tone of instruments like the Roland Juno-60. Just have a listen to some of his work and check the interview above.

Words to Dead Lips Closing Night Excerpt

As I’ve mentioned in some previous articles, I have been working on a multi-media dance collaboration, Words to Dead Lips, with Annichia Arts since last December that has finally come to a close. We staged three performances at Intermedia Arts in Minneapolis this weekend to a mostly full house. My part in the collaborative effort was to produce the music, and I was given an open mandate to do so. As is my preference, I opted to perform the work to the dance and projected imagery, rather than submit pre-recorded material. Although I adhered to an agreed framework for the soundscape, the improvisational nature of this approach made every performance unique.

The main tool that I used to generate the sound was my Max for Live patch, Grain Machine that explores granular synthesis via a multi-touch controller. I loaded it with five samples including Snow Melting into Lake Superior, One Hundred Sounds in Eight Seconds, High and Low Frequency Drone, and a couple of others for the piece.

Another component to the sonic environment was the noise shield. This device, that I built into saucer sleds, was used by the dancers to synthesize sounds using body contacts and a light dependent resistor. Here’s a five minute excerpt of audio from the closing night’s performance.
