Harmonic Architect

Additive Synthesis & Frequency Band-Limiting Workstation

Audio Output Device setSinkId
Hardware Output Router: Routes master audio to physical outputs (e.g., Headphones, External DAC, Studio Monitors) via Web Audio setSinkId. (Requires Chromium browser or compatible hardware context).
Audio Input Device (Mic / Line-In)
Hardware Input Route: Feeds external audio directly through the parallel frequency band filter bank, allowing you to spectrally isolate live mic input alongside synthesized harmonics.

Additive Synthesis Generator

24 Partials
Timbral Harmonic Preset
Acoustic Breakdown: Additive synthesis constructs complex timbres by summing discrete sinusoidal partials. Warm Pad utilizes exponential amplitude damping with subtle octave reinforcement for a lush, smooth body.
Harmonic Spectrum Matrix Red = Filtered Out | Blue/Cyan = Transmitted
Base Fundamental Pitch ($f_0$) 130.81 Hz (C3)
Inharmonic Partial Detune / Dispersion 0.00
Attack / Release Dynamics (ADSR Envelope) 0.05s / 0.8s

Concurrent Frequency Band Limiter

Frequency Band Window Presets
Preset 1 Mechanics: Generates acoustic windows across deep sub-harmonics (1–50Hz), presence articulation (2–4.5kHz), harmonic sizzle (5.5–8.5kHz), brilliance (10–14kHz), and hypersonic air (15–24kHz). Any partials falling between these bands are strictly brickwalled.
Active Band Slices (Concurrent Filtering) Min Hz / Max Hz per channel
Master Output Gain 75%

Real-Time Multi-Band FFT Spectral Analyzer

Logarithmic Scale: 20 Hz - 24,000 Hz
Green Overlays = Transmitted Band Filters | Cyan Trace = Live Output FFT
