Module pair_phase 

Corrected phase and cancellation checks between main-channel pairs (ADR 0035).

Constants

BAND_HZ

ADR 0035. Inspection range in hertz.

CENTERS_HZ

One-third-octave centre frequencies in the inspection range.

FLOOR_DB

Lower bound for cancellation values in decibels.

LOSS_DB

Cancellation threshold in decibels.

MAX_PAIRS

Maximum number of reported pairs.

Functions

band_edges

The band edges in hertz: BAND_HZ.0, the geometric means of neighbouring centres, then BAND_HZ.1, so the outer bands reach the ends of the inspection range.

bands

Measure phase difference and cancellation in each one-third-octave band.

check

Report main pairs with at least one band at or below LOSS_DB.

Type Aliases

Band

One band’s (low Hz, high Hz, phase degrees, cancellation dB) result.
