soundy_thingy

soundy_thingy is a collection of self-contained, browser-based audio instruments and tools focused on generative sound design, resonance, and ambient synthesis. Most tools are single-file and work completely offline when opened directly. Main Project: synth.html — A fully client-side generative ambient synthesizer. A polished, playable instrument that generates evolving, musical, never-repeating ambient drones and melodic sequences using only the Web Audio API. - Zero dependencies, zero build step, zero network calls. - Open the file and it just works (even from file:// or USB drive). - ~37 KB total. Key Features: - Generative Engine: Uses a seeded PRNG for reproducible yet endlessly varying music. - 6 Voice Types: Pad, Pluck, Bass, Bell, Drone, Noise-wash. - Scales & Geometry: 14+ scales + geometric pentatonics (circle of fifths, golden spiral, pentagram, equilateral, etc.). - Modulation Matrix: Route LFOs to parameters, FX, density, etc. - FX Chain: Ping-pong delay, procedural reverb, chorus, drive, stereo widener + limiter. - Mood Macros: Warm / Calm / Glass / Dark / Bright. - Visualizer: Spectrum, oscilloscope, and orbit view. - Transport, persistence, presets, keyboard shortcuts, and mobile-friendly layout. Resonarium × Biosentinel: An actively maintained audiovisual instrument with a toggleable Sentinel Mode overlay and a headless CLI controller. Its distinguishing property is that the Python and JavaScript halves agree bit for bit, producing the same 64-bit seed, PRNG stream, and placements. Offline behaviour: Every file opens from file:// with the network off, making zero off-host requests.
