Expand description

ISO 3382 single-band acoustic metrics for one RIR.

Fields§

§edt_s: f64

Early decay time — Schroeder slope over 0 → −10 dB, extrapolated to a 60 dB drop. In seconds.

§t20_s: f64

T20 reverberation time (−5 → −25 dB, extrapolated to 60 dB). Seconds.

§t30_s: f64

T30 reverberation time (−5 → −35 dB, extrapolated to 60 dB). Seconds.

§c50_db: f64

Clarity at 50 ms (in dB). Higher = more speech-intelligibility-friendly.

§c80_db: f64

Clarity at 80 ms (in dB). Standard music clarity parameter.

§d50: f64

Definition: ratio of early (≤ 50 ms) to total energy. Dimensionless.

§ts_s: f64

Centre time (seconds). The temporal centre of gravity of h².

§edt_r2: f64

R² of the EDT linear fit (0..1). < 0.9 is a quality warning.

§t20_r2: f64

R² of the T20 linear fit.

§t30_r2: f64

R² of the T30 linear fit.
