SOPCOS: Declarative Audio Engine
Precision binaural entrainment & AI-driven subliminal audio
What it does
SOPCOS Brain Lab is a declarative neuro-acoustic audio platform powered by CEP v4.1. Built with Web Audio API and C++ JUCE FFI, it generates precision binaural entrainment, 3D spatial soundscapes, and acoustic shadow masking for subliminal audio processing. By integrating real-time Wear OS biometric data (HR & SpO2), SOPCOS dynamically adapts sound to your physiology—delivering evidence-based audio protocols for deep focus, cellular recovery, lucid REM sleep, and mental reset.
Neural Frequency Modulation Lab
Pioneering the future of cognitive enhancement through binaural industrial precision. Modulate, monitor, and master your neural output with brutal efficiency. "The Alpha modulation latency is practically non-existent. My synaptic response time has increased by 14% since initialization." "Deep immersion in Theta state is unparalleled. The industrial precision of the binaural engine is exactly what my core requires." "Minimalist, brutal, and effective. The interface doesn't get in the way of raw frequency management. Five-star throughput." Synchronize your neural interface across all mobile endpoints for continuous frequencyfrom binaural.sopcos.org

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
