Expand description

Null-test metrics of b against reference a.

Fields§

§offset_samples: i64

Samples by which b lags a (negative: b leads). Found by FFT cross-correlation.

§offset_s: f64§alignment_correlation: f64

Normalised cross-correlation at the chosen offset (−1..1).

§polarity_inverted: bool

b is polarity-inverted relative to a.

§compared_frames: usize

Frames compared after alignment.

§length_difference_s: f64

Duration of b minus duration of a (seconds).

§rms_diff_db: f64

RMS of a − b over the aligned region (dBFS, floored at −240).

§null_depth_db: f64

rms_diff_db relative to the RMS of a (how deep the null is).

§diff_peak_db: f64

Peak of a − b (dBFS).

§peak_delta_db: f64

Peak of b minus peak of a (dB).

§rms_delta_db: f64

RMS of b minus RMS of a (dB).

§loudness_delta_lu: f64

Integrated loudness of b minus a (LU); null when either is unmeasurable.

§gain_db: f64

Least-squares gain that best maps a onto b (dB).

§si_sdr_db: f64

Scale-invariant SDR of b against a (dB, capped at 200).

§identical: bool

Same length, zero offset, and bit-identical samples.

§verdict: String

identical, transparent (null below −90 dB), gain_only, similar, or different.

§notes: Vec<String>
