Today I sorted a new method for sonification of OpenBCI EEG data. This process has gone through many forms, but it needed to be cleaned up and clarified. This iteration uses the average amplitudes of each brainwave type to set the parameters of a hybrid AM/additive synth. The synth sounds the max frequencies for the 5 wave types, modulated by the amplitudes for each, and then adds them all together – for each of 8 data channels.
This results in a much more natural sounding representation of the data – the wave types are in fact octaves of one another! This new patcher also makes it incredibly simple to spatialize the data set over 8 speakers to model the 8 electrodes in the EEG instrument. Arrange these speakers around you in the same configuration, and you will hear my brain as if you were inside of it…!
Haha… maybe a bridge too far for some of you! 🙂 Start with your audio low; the sound begins after about 30 seconds of setup.
A note: There is a considerable amount of clicking you can hear when the gain is up, but I believe this is actually a low frequency beating, artifacts caused by the different channels interfering with each other. I can’t wait to test this on a multi-speaker system to find out how that works in real space, instead of cramming 8 layers into a stereo headset.
Stay tuned! I’m in the process of booking a venue for the first 8.1 3D sound performance of “I Am Sitting…” in early May.
An installation of photographic work is showing at UMaine’s IMRC Center between November 27 and December 1, 2017. The show, TRANSFER, is being exhibited in the Graduate Studios (Room 118) and is open to the public during staff hours (9am to 7pm), and features large format images in abstraction of the still-life compositional form.
An artist reception is scheduled for Thursday, November 30, in conjunction with Studio Ajar’s latest event. During the event, the installation will also showcase a selection of these fantastical images via larger-than-life projections.

On Wednesday, July 12, Alicia will give a brief talk about her work leading up to and including her current research into the combination of biosignals and generative feedback loops.
Hangar.org hosts the monthly event, Paratext, at which a roster of artists-in-residents or other local collaborators have a chance to introduce their work and ideas to new audiences.
Paratext˚19 begins at 7PM in Hangar’s Sala Ricson. For directions and updates, you can follow the event on fb.
Alicia has been awarded a research and development grant by Hangar Interactive Labs in Barcelona, Spain, for the summer of 2017. With this opportunity, she will be continuing development of “I Am Sitting…” by building a research-grade EEG headset based on the OpenBCI Ultracortex Mark III Nova.
The Ultracortex is a 3D printed harness for the EEG sensor array, supported by OpenBCI’s Cyton Biosensing Board, a microcontroller with an open-source development platform for biodata research.
Champlin will be in residence in Barcelona from June 1 to August 23, 2017. A brief talk about her work is scheduled for July 12, as part of Hangar’s Paratext series.
On May 6, Alicia will participate in a collaborative installation at Fort Knox. Read the Bangor Daily post here.
On Friday, April 28th at 7 p.m., the IMRC Center will host an evening of experimental performance. Studio Ajar: Performance Edition is a showcase of performative works developed by UMaine Intermedia MFA students over the course of several months or more. Alicia will be one of four showing as part of a program entitled “Four Aspects of Contemporary Performance.”
Composer and performer Steve Norton is a first year MFA student with over 30 years of music performing experience; he will perform an experimental music composition inspired by a Samuel Beckett text. Josh Couturier is a pop media artist exploring meditation as a source of enlightenment and direction during construction of art projects; he will perform a piece entitled “Entangled”. Alicia Champlin and Eleanor Kipping are both second year MFA students. Alicia’s work, entitled “I am Sitting”, draws inspiration from Alvin Lucier and Nam June Paik and presents itself as a performative installation. The piece exploits biometric data and feedback loops to explore issues of neutrality and mediation. Eleanor’s work explores the identity politics surrounding the black female experience in America in light of colorism and racial passing. Her piece, “I Will Not Say Nigger”, is a spoken word performance that explores the language, both spoken and unspoken, between races throughout generations of segregation and racism in the United States.
This performance will be followed by a reception with the artists. Light refreshments will be provided and audiences are invited to bring beverages and additional refreshments and delights.
