MqaAudioWeights interface

Weights controlling the MQA-AUDIO composite score aggregation (SVTA registry 24). Same start-at-100-subtract-penalties model as MQA-VIDEO; see the PureScript QualityMetrics module for the exact math.

Properties

Property	Type	Description
clipWeight	number	Multiplier on clip_ratio × 100 (clipping never is).
deadChannelPenalty	number	Flat penalty while a channel is dead.
humEnergyThreshold	number	Hum energy at/below this is noise floor, ignored.
humWeight	number	Multiplier on (hum_energy − threshold) × 100.
loudnessTargetLufs	number	Integrated-loudness target, e.g. -23 (EBU R128) or -24 (ATSC A/85).
loudnessToleranceLu	number	No penalty within target ± tolerance (LU).
loudnessWeight	number	Penalty per LU beyond the tolerance band.
silencePenalty	number	Flat penalty while silent (silence can be legitimate content).
toneRatioThreshold	number	peak_ratio at/below this is normal content.
toneWeight	number	Multiplier on (peak_ratio − threshold) × 100.
truePeakMaxDbtp	number	True-peak ceiling (dBTP); at or below is free.
truePeakPenalty	number	Flat penalty when true peak exceeds the ceiling.
