HeadSpace

See the full length video here.

HeadSpace is a project under development since 2025, initially for presentation at ICLC in Barcelona. This performance was peer reviewed and accepted for publication in the ICLC 2025 proceedings. It premiered on Thursday, May 29, 2025 at Sala Beckett in Barcelona, and was since included in The Generative Art Museum’s 2025 Responsive Dreams festival.

HeadSpace at ICLC 2025

In this project, the performer’s live EEG data is used as a control signal, focuses on the naturally occurring octaves (frequency doubling) within the EEG signal spectrum. As a means of sonifying the brainwave signals, they are mapped into a sequence of audible frequencies through live coded sound synthesis, and stepped through a modulating harmonic series derived from Schumann resonance frequencies. The two domains (EEG and the Schumann resonance) essentially overlap in the electromagnetic spectrum, posing an interesting synchronicity and thought experiment. Through this pairing, manipulated by live-coding 40 individual synthesizers and programmatically mixing the signals in real time, the work brings 2 omnipresent but hidden phenomena together in a soundscape narrative of biofeedback in play with atmospheric feedback.

ABSTRACT

Working with biodata as a control signal requires challenging decisions to be made about
how the dimensions of the signal should be mapped onto whatever it is controlling. As most
biodata inherently has a very low signal to noise ratio, the task is to avoid arbitrary
mappings that end up essentially creating a noise filter. The key is to find a focus in
potential patterns, and to amplify these in a way that allows them to articulate themselves.

In this project, HeadSpace, the performer’s live EEG data is used as a control signal, and will
be focused on the naturally occurring octaves (frequency doubling) within the EEG signal
spectrum. As a means of sonifying the brainwave signals, they will be mapped through live
coded sound synthesis into a sequence of audible frequencies, and stepped (over time)
through a modulating harmonic series derived from Schumann resonance frequencies. The
two domains (EEG and the Schumann resonance) essentially overlap in the electromagnetic
spectrum, posing an interesting synchronicity and thought experiment.

Through this pairing, manipulated by live-coding 40 individual synthesizers and
programmatically mixing the signals in real time, the work brings 2 omnipresent but
hidden phenomena together in a soundscape narrative of biofeedback in play with
atmospheric feedback.

This piece draws on previous work with sonified EEG in live performance (see links) and
work with live coded sound performances using TidalCycles, MaxMSP, and PureData to
explore the complex layering of primitive oscillators through AM & FM synthesis, creating
spaces for a rich sound vocabulary to emerge from noise.

The primary inquiry at the heart of this work is to explore live biofeedback in a
performance methodology, that demonstrates (audibly) the recursive effect of live
manipulation of live sonified brainwaves in situ with the brain itself as both transmitter and
receiver. The first member of the audience is the performer, problem-solving the sound of
problem-solving, and the rest of the room is invited inside this intimate space, which is
made intelligible and large enough to share through the application of earth’s own
harmonic series.

Given the personal (and self-reflexive) nature of biofeedback generally, what does it mean
to practice biofeedback in a live setting? Inevitably, the larger audience is part of the
atmosphere and thus part of the feedback being received, and as such becomes a
component of the control signal itself. Liveness itself can be characterized as being swept
up in shared ephemeral experience, a collective witnessing, and it is this expansive intimacy
that this practice seeks to capitalize on, as a further amplification of the control system in
play.

dúo

dúo, a collaboration between Champlin & Niklas Reppel, is an improvisation for bow chime (sometimes also called a steel cello , even though there are subtle differences) and live coding on an multi-channel setup. In play, the broad acoustic vocabulary of the bow chime is picked up with a single microphone in the room, to then be manipulated, layered and spatialized on the multi-channel setup through live coding, blending the two in a dialog between pure vibration and processed sound.

The performance is inspired both by cymbal baths, a kind of sound bath with a more meditative focus, as well as performances involving room resonance and feedback loops, such as the concepts by the late, great Alvin Lucier. Feedback from the loudspeakers, room resonances and background noise, including noises and utterances by the audience, are invariably picked up by the microphone. This augments and blends with the deeply resonant sound of the bow chime, creating a grand, sometimes unpredictable but beautiful feedback loop between performers, space and audience.

Using live coding (in Mégra, an abstract, high-level language) to manipulate the sound allows to interact and improvise through concise code gestures, while sharing the thought process with the audience through projecting the code. The language embraces a certain degree of non-determinism, and also allows the performers to lean back and listen to the sound unfolding.

Four instances of the project have been performed so far:

Düsseldorf 2024 (video)
Karlsruhe 2023
Barcelona (/*VIU*/) 2023 (video)
Barcelona (Antic Forn de Vallcarca) 2022 (video)

Neowise 5.8 V/E

This work was peer reviewed and selected for presentation and publication in the proceedings of ICLC’23 in Utrecht, NL.

Neowise 5.8 V/E is a constructed/deconstructed soundscape, last of a series of minimalist and ambient improvisations inspired by the unfathomable orbit of the comet they are named after. An earlier iteration was published on Down the Rabbit Hole (Call It Anything Records, 2021)

Using just 2 or 3 samples in TidalCycles, it layers the ringing of the spheres, and beams out harmonics like a prism splitting light into distinct colors. The samples used are recordings of a bow chime, a very physical instrument which plays you in return. Recordings of this acoustic behemoth cannot track the experience of it live, but by manipulating these samples, we find new means to engage with the tangible shapes of orbits and conjunctions. In this last scene of the series, the live bow chime also joins the stage as recompense to the early studies’ original explorations of ebb and return. Dedicated to Matt Samolis in gratitude for his mentorship.

Unfortunately, audio and video documentation of this performance have been lost due to a failed hard drive before it could be published. I’m holding out hope that somewhere a copy survives, but I haven’t found it yet.

Down the Rabbit Hole

Down the Rabbit Hole is a compilation album made by the TOPLAP Barcelona live-coding community, released in March 2021. Champlin’s contribution to the album, the track “Neowise3,” is a minimalist study of resonance and timbre.

The album, published by Call It Anything Records, is available via Bandcamp as a digital download or CD with a limited edition laser cut booklet containing personal bios and insights about the pieces from each artist contributing to the project. A digital copy of the source code for each track is included with both formats.

From the booklet:

“Neowise3” is a constructed/deconstructed sound- scape, one of a series of minimalist improvisations. Using very few samples, it layers the ringing of the spheres, and beams out harmonics like a prism splitting light into distinct colors. The three short samples used were sounded and recorded live on bow chime by Matt Samolis of Barre, Mass. The bow chime is a very physical instrument which plays you in return. Recordings of this acoustic behemoth cannot track the experience of it live, but by manipulating these samples, we find new means to reckon with the tangible shapes of orbits and conjunctions. Many thanks to Matt for his collaboration and mentorship.

La Obra Invisible (Incorpórea)

‘The Invisible Work’

La Obra Invisible is a collaboration under the collective name Incorpórea. Quoted from the collective’s website:

algorithmically generated interference waves overlaid with the text "Incorpórea"

Incorporéa is a collective of two artists, Yalili Mora and Alicia Champlin, who have both worked extensively in the task of manifesting the invisible of our inner human worlds.

Yalili uses painting / portrait as a metaphor, with concerns about a deeper exploration of technological interfaces. Alicia has a history of using technological interventions as a mediator between creativity and data.

In collaboration between these two multimedia practices, “The Invisible Work” aims to reconcile the emotional and empirical realms, reaffirming our physical agency within our environments while simultaneously exploring the implications of our most ephemeral traces. In this mapping process, what we hope to emphasize is the balance between individual sovereignty over this psychological landscape, and its vulnerability to environmental and interpersonal forces, as well as the limits of our agency as these traces spread throughout the world in general.

The piece is an interactive installation featuring a Chladni plate as a visualization of the sonified brainwaves of both artists, signal-mixed together by visitors in real-time using a custom application built by Champlin, and presented along with the artists’ painted portraits (part of Mora’s series “Retratos sin rostros aparentes”, or “Portraits without apparent faces”).

This work was installed as part of Recorreguts Sonors: Accions i Mutacions Sonores at the Convent de Sant Agustí in Barcelona, 19-23 November of 2019.

Last week, I took my turn at the table during the monthly TOPLAP-bcn session, and we had the opportunity to capture a 3D/ambisonic recording.

I am new to Tidal Cycles, the language I was performing in, but I still feel like these live sessions are valuable as an exploration of algorithmic composition, even if my own composition strategies as an improviser are still evolving. So far I’m finding ample opportunity to experiment with algorithmic transformations of pattern sequences and samples. This piece has up to 7 lines of code running at one time, no more. The transitions you hear are triggered by recompiling individual lines in real time with updated parameters and conditionals.

The recording was made with Zylia ZM-1, a 3rd order ambisonic microphone, and rendered by Sfëar Studio for binaural listening. Disclosure: I am married to the lead developer at Sfëar. 😉

Enjoy! Please feel free to add comments. If you want to hear more, I am on the line-up for the end-of-season Algorave scheduled for July 19 – more info soon!

I Am Sitting… IV

Past performances:

Link to video of “I Am Sitting… IV” at Without Borders Festival in May, 2018.

I Am Sitting. . . is an immersive performance and sound installation in which a live performer is seated, in meditation and wearing an EEG instrument, in the center of an array of 8 inward-facing speakers. Eight channels of live-streamed EEG data are transformed into a sonic landscape that is both intimate and expansive. The sounds are spatialized in accordance with the geography of the eight electrode sensors of the instrument in order to create the sense of listening to the brain from the point of view of its owner, the performer.

The performance space is defined by the perimeter of speakers, and invites the audience to enter into the space, move about within it, and become part of an immersive bio-feedback experience. The resultant sound responds to the environment, especially the presence of the audience, by articulating external influences on the brain activity of the performer.

This work speaks to the thresholds at work within our perceptions – of self, of environment, and the distinctions between the two.

It also illustrates a dialectic between author and subject. Do our perceptions and actions generate our world, or are we experiencing a determined universe, an algorithm that is simply playing itself out? This quandary extends from the performer in meditation through the audience experiencing the piece, both questioning their role at the threshold of influence.

Finally, I Am Sitting. . . hovers in the space between the intimate and the interpersonal. How much of me is you? Can we fine-tune our perceptions to be more, or less, sensitive to our social conditioning? Which signals qualify as communication? The piece puts the audience (and performer) in an active state of testing these thresholds, teasing our intuitive and intellectual senses to dialogue with one another and form dynamic hypotheses about the nature of perception and interaction.

This piece is dedicated to the inimitable Alvin Lucier.

Lasting and Leaving

“Lasting and Leaving” is a generative sound art installation built with MaxMSP for a multichannel array. Random periodic sequences are triggered by foot traffic in a public space. Its effect is such that a person walking through the space may find a particular sound associated with them upon their entry seems to follow them as they make their way, while layering with the sounds of others doing the same.

This installation was inspired by a 1913 score ‘Musical Sculpture’ by Marcel Duchamp, later interpreted as ‘Sculptures Musicales’ by John Cage: “Sounds lasting and leaving from different places and forming a sounding sculpture that lasts.”

The piece is also a personal recalling for me, at the end of my MFA studies. I began my research into systems thinking and communication thanks to a pilgrimage undertaken in Japan, which cemented for me the idea that an environment becomes the embodied experience of those who travel through it, leaving traces and taking pieces with them. Read the installation’s wall text here.

The first full installation of “Lasting and Leaving” took place in the Without Borders Festival in May-June of 2018.

Duet for Bow Chime & Live EEG

Duet for Bow Chime & Live EEG was a live improvisational performance recorded in the IMRC’s AP/PE on March 27, 2018.

This work uses a modified technique, which includes live EEG (brainwave) data in combination with bowing. EEG data processed through custom MaxMSP programming is converted to a sound signal and output through a pair of transducers attached to the resonator of the bow chime.

The effect is such that the bow chime’s range of frequencies becomes focused where it is resonant with the EEG signal, and the two work together to produce complex layers of sound. Further, the normal haptic feedback loop between the bow chime and player, which allows the player to choose sympathetic bowing actions, is layered with the added element of biofeedback from the EEG sounds generated by the player in action.

An upcoming performance using this technique is scheduled for July 9, 2018, at the Apohadion Theatre in Portland Maine.

Champlin uses a modified bow chime developed by Matt Samolis. She has been studying ‘cymbal bath’ techniques with Samolis since 2017. The instrument is modeled on the original bow chime invented by Robert Rutman in 1967.
