Primate Methylation Series
Case [R] v. Control [L]
Project: Attempt auditory comparative analysis of DNA Methylation & RNA Expression Data
Design: RNA-Seq WIG files files fed into PureData after adjustments to fill no-coverage base pair locations.
Per base per sample coverage used as waveform, FM Modulator and AM Modulator [as described below sample audio tracks].
Samples merged to left (4x MR samples) and right (4x PR Samples) channels.
Variation between left and right could denote regions of interest for further exploration.
Result: No sufficiently perceptible occurrence was found.
Further exploration is needed to determine if this concept has any utility beyond the artistic.

Sample Patch [Visual]:

Sample 1

Mapped RNA-Seq Reads 15Kbp as waveform at 44.1Kbp/s

Sample 2

Coverage as FM Modulation : 3k base pair segment
Carrier tone frequency shifted up based on per base coverage per sample.

Sample 3

Coverage as AM Modulation : 3k base pair segment
Per sample carrier tones (harmonic) amplitude boosted based on per base coverage.
Kbps = Kilobasepairs or 1,000 nucleotides (letters) of sequence

20 Speaker 3 Zone Custom Hanging Speaker Array
Project: Design a custom 3 zone hanging speaker array covering 326m2(3500ft2)
Design: Custom speaker housing was designed using basic hardware and reclaimed materials.
Cabinets each contained one two-way 165mm 4Ω speaker.
Dense cardboard formtubes were selected for basic cabinet both for simplicity of material and acoustic properties
Acoustic batting to minimize case design frequencies was made using a combination of dense fiberglass duct liner and loose insulation fiberglass
End caps and mounting were custom CNC cut to flush fit from 9.5mm (3/8") plywood
Speaker routing was done using high gauge wire (for length) and a combination of parallel and series circuits to produce a 6Ω line impedance at the amp

Nox Arcana
Project: An immersive environmental exploration of time and space
Design: Video was developed using algorithmic methods intended to produce effects of pre-temporal influence
Sound design as four channel surround using a combination of ambient washes and NASA Voyager data.
Explorations are referenced through concepts of the delay between transmission and receipt of Voyager sounds
As well as the data itself having been delayed before arrival at the probe
Run Time: 30 minute loop
