Acoustic Frequency Spectrum
Real-time FFT Response
Mechanical sound reproduction in the 1890s-1920s cut off high frequencies (~1.2 kHz) while introducing mechanical needle friction, speed fluctuations (wow/flutter), and severe horn resonance. Visually, this acoustic age mirrors heavy sepia vignetting, metallic brass glare, and physical surface grain.
