On Monday September 5th I took part in Netrooms performed at The University of Nottingham Ningo, China campus.

Netrooms: The Long Feedback is a participative network piece which invites the public to contribute to an extended feedback loop and delay line across the internet. The work explores the juxtaposition of multiple spaces as the acoustic, the social and the personal environment becomes permanently networked. The performance consists of live manipulation of multiple real-time streams from different locations which receive a common sound source. Netrooms celebrates the private acoustic environment as defined by the space between one audio input (microphone) and output (loudspeaker). The performance of the piece consists of live mixing a feedback loop with the signals from each stream.

Experiments in balloon motion and sound using an MS Kinect depth sensing camera.

Created for the Carnegie Mellon 1st & 2nd year MFA Graduate show entitled “Fresh Baked Goods” at Bakery Square, April 2011.

Description

A machine stands in a room surrounded by balloons. Circulating fans blow the balloons over the machine which creates sound based on their movements.

Mode 1: Tones

Balloon height and x/y position control the pitch and panning of a treble and bass voice. The tones can be quantized into a certain key or a glisssando can be employed for a theremin-style effect.

Mode 2: 99 Luftballons

The playback speed of Nena’s 99 Luftballons is controlled by balloon height. The balloons must be kept in the air for the song to play. Feed the machine.

Built using Open Frameworks, ofxKinect, and OpenCV for balloon tracking and Pure Data for sound generation/playback.

Music: 99 Luftballons by Nena

Fellow student Luke Loeffler and I both presented Richard Serra and Nancy Holt’s 1974 “Boomerang” audio/video piece to separate classes at CMU. A delay line is used to throw Holt’s voice back at just the right speed to where her brain becomes confused and her speech and comprehension slows. She is filmed on live television as she explains the experience.

Pure Data

We made a simple Pure Data patch which replicates the experience. Plug in a microphone and headphones (preferably closed ear types) and give it a shot.

EDIT: The original patch was using a 100 ms delay. Later on I was told the original piece used 283 ms, calculated form research into cognitive perception, etc. I have updated the speed and, indeed, the effect is much more pronounced.

RjDj

I took the Pd patch and then made an RjDj scene which can be run on an iPhone or iPod Touch. RjDj is a “reactive music” environment that runs live, interactive songs.

Install RjDj on the App Store and download Boomerang from the Soundtrips section. The effect works really well with earbuds, just make sure to turn up the volume. You can also make recordings and upload them to RjDj if you create an account.

On Sunday April 4th I took part in Netrooms [for percussion].

This is an invitation for a special Netrooms performance Netrooms [for percussion]. The performance was commissioned by percussionist Jonathan Shapiro and will take place on Sunday 4th April at the Staller Center music wing, Room 0111 (choral room) at Stony Brook University in Stony Brook, NY

Netrooms [for percussion]
Pedro Rebelo, 2009

Netrooms [for percussion] explores the sound of a local percussionist as it travels through various acoustic environments. Each participant will set up a microphone capturing a space as nearby loudspeakers stream the sound of each percussion instrument. Please choose unique and perhaps extreme acoustic spaces such as bathrooms, concert halls, outdoors, domestic spaces, outdoors etc…
Participants will not be required to produce sound but incidental sound from the environment is welcome…

Tim Devine and I made 4 improvisations for the radiospotting project in Linz, Austria which is taking place Sep 11 – Oct 31 2009. Small radio transmitters tuned to 103Mhz are situated at multiple locations around the city and participants are encouraged to bicycle about the city with portable radios.

Writers and musicians collaborated on each space, with the writer’s text used as inspiration for locational compositions.

We developed and improvised 4 pieces for Pure Data, Roland drum pad, and electric guitar:

Performance for Christmas calendar project in Gothenburg Sweden on Dec 9 07. I accompanied Oscar Ramos as he played a window with a speaker and contact mic using feedback through an amplification system.  The performance lasted about 15 minutes and was viewed from the street below.

first take frenzy

this album is an exercise in spontaneity. what can we do with 1 microphone, 2 days, and no experience playing together? the title is correct as 80% of the tracks are first takes, the rest being 2nds.

At the beginning of my Art and Technology masters program, all of the new students were required to present both their background and their work.

I made a music video for “The Sloppy Bytes” (4 of me) in one night as part of my presentation.

A simple blue screen using the color test of a projector provided the back drop and my friend Daniel provided the DV camera.

“sloppy” is the theme as I am tired of digital music being “perfect”
