📊 Real-Time Octave Spectrum (RTA)
Profile: Balanced
31.5 Hz — 16 kHz
Cathedral Room Mode & Low-End Boom
Analyzing low-frequency energy (<150 Hz) vs midband. Cathedral ceilings frequently induce resonance buildup that masks speech clarity.
Ear Fatigue & Harsh Vocal/Cymbal Resonance
Monitoring presence frequencies (2.5 kHz - 4.5 kHz). Highly reflective plaster/stone surfaces can cause piercing listener fatigue.
