How the 1-minute AI Symphony Orchestra works (HTML + Web Audio)
  1. Load Audio and (optionally) click Analyze 60s to auto-detect notes & tempo.
  2. Export CSV (t,m,b) then load CSV into A and/or B panels.
  3. Choose A (10–16) and B (6–16). Total stays 32, no overlap. Locks respected.
  4. Set Conductor/Key/Tempo/Quantize/Swing/Humanize/Reverb/Spread, plus Cadence & Pace.
  5. Use Per-Chair Variants (bright/warm etc.).
  6. Press Play for a 60s render; lights blink on sounding chairs. Export WAV to save audio.
  7. Need to start over? Use Clear buttons (Audio / A / B) or Reset for a full reset.

How the 32-Chair Symphony Works — Methods & Math (v1)
  • Pitch & Bass Detection: autocorrelation + zero-crossing estimate → MIDI map.
  • Key Detection: Krumhansl-Schmuckler profile correlation → best major/minor root.
  • Tempo: onset deltas → median IBI → BPM normalized to 60–180.
  • Quantize & Swing: snap to grid q = round(t/grid)*grid, odd positions get swing offset.
  • Routing: pitch range + family opening bias (Strings→Winds→Brass→Perc) to seats.
  • Scheduling: look-ahead event buffer streams notes to WebAudio buses.
  • Timbre: SoundFont playback per seat → panned buses → hall reverb + compressor.
Key: argmax_r ⟨profile_r , histogram⟩ BPM: bpm = clamp( round( 60 / median(Δonset) ) × 2^k , 60..180 ) Quant: q(t) = round(t / grid) · grid; swing: if odd grid → q += s·grid/2 Assign: section = f(pitch, isBass, familyOpen_t)
This is an early HTML-only AI symphony. As the codebase grows, it will fuse analyzer, arranger, orchestration, and rendering into a single unified pass.
Interstellar Star Clock — Relativity, Energy ↔ Mass & Stellar Geometry
  • Special Relativity — Orbital Time Dilation
    Proper clock vs fast-orbit clock:
    Δt' = Δt · √(1 - v² / c²)
    Δt = time for a stationary observer (mission control)
    Δt' = time for the moving probe / ship
    v = velocity of the orbiting object, c = speed of light
    → Use this to show subtle CST "time slip" on high-speed arcs or slingshot maneuvers.
  • General Relativity — Gravitational Time Dilation
    Near massive bodies (stars, gas giants, black holes):
    Δt' = Δt · √(1 - 2GM / (r c²))
    M = mass of the body, r = radial distance from its center
    → Clocks deeper in the gravity well run slower; your clock can show this as a subtle offset ring.
  • Energy ↔ Mass Balance (Engine / Computer Core)
    Einstein link between "stored mass" and "usable energy":
    E = m c²
    m acts like stored "memory mass" inside the CST core / SPR-C brain
    E is active processing power, RF, photons, logic transitions
    → In visuals you can let high-E bursts glow, while high-m zones render as dense, quiet memory lattices.
  • Star Coordinate Mapping — RA/Dec → 3D
    Celestial coordinates:
    • Right Ascension α (sky longitude from vernal equinox)
    • Declination δ (sky latitude from celestial equator)
    For a unit celestial sphere:
    x = cos(δ) · cos(α)
    y = cos(δ) · sin(α)
    z = sin(δ)
    → Plug real catalog RA/Dec into this and the Interstellar Star Clock can place actual stars / constellations around the orchestra.
  • Sidereal vs Solar Drift — True Stellar Day
    Solar day ≈ 24h, sidereal day ≈ 23h 56m 4.1s.
    • Drift per day ≈ 3m 55.9s (~1° of sky rotation)
    → Over many days, you can let the star backdrop slowly rotate relative to the solar clock, revealing the real galactic rhythm.
  • Light-Time Delay — Seeing the Past
    Signal / photon travel time:
    t = d / c
    d = distance (km, AU, light-years, parsecs)
    t = delay between emission and observation
    → Your clock can tint or fade objects by how "old" their light is, showing that every orchestra performance is already slightly in the past.
These equations let the Interstellar Star Clock stay poetic but physically anchored: relativity for time slippage, E↔m for engine/computer load, and RA/Dec + light-time for accurate skies.
