📖 Acoustic Engineering Parameter Definitions (Table 2 Reference)
Parameter Acoustic Definition DSP Simulation Implementation Perceptual Audio Impact
Volume (V) Total enclosed or effective 3D air capacity in m³. Scales mean free path (l = 4V/S) and impulse buffer memory duration. Controls boundary bounce frequency; smaller volumes sound tight, larger sound vast.
Dimensions (L×W×H) Axial room boundary dimensions in meters. Calculates tri-axial Rayleigh modal eigenfrequencies: f = (c/2) × √((n/L)² + ...). Simulates room standing waves; prevents unphysical square flutter ringing.
RT60 (1kHz) Standard Sabine reverberation decay time for energy to drop 60 dB. Sample-accurate exponential envelope: h(t) = noise(t) × e-t / τ. Dictates persistence of spatial tails and harmonic elongation.
DRR (Distance) Direct-to-Reverberant energy ratio in dBFS (-24 to +18 dB). Constant-power gain scaling: directGain = 10DRR/20 / √(1+10DRR/10). Controls listener proximity to the sound source without altering overall gain.
Pre-Delay & ITD Initial boundary gap plus Woodworth interaural time difference. Discrete silence buffer padding + channel 1 time offset (0.03 to 50 ms). Creates true binaural head-related spatial width on headphones.
Bass Warmth (BR) Bass Ratio: low-frequency (125-250Hz) decay relative to mid-band. Time-dependent exponential low-frequency booster applied during IR synthesis. Replicates physical mass wall reflection behavior, enriching spatial body.
