Weights driving the single composite MQA-AUDIO score (SVTA registry 24). Same start-at-100-subtract-penalties model as MQA-VIDEO (see computeMqaAudio in Avp.Types.QualityMetrics for the exact math).

Description |
silence_penalty |
flat penalty while silent (silence can be legitimate) |
||
clip_weight |
multiplier on clip_ratio x 100 (clipping never is) |
||
dead_channel_penalty |
flat penalty while a channel is dead |
||
loudness_target_lufs |
integrated-loudness target, e.g. -23 (EBU R128) / -24 (ATSC A/85) |
||
loudness_tolerance_lu |
no penalty within target +/- tolerance |
||
loudness_weight |
penalty per LU beyond the tolerance band |
||
true_peak_max_dbtp |
ceiling; at or below is free |
||
true_peak_penalty |
flat penalty when true peak exceeds the ceiling |
||
hum_energy_threshold |
hum energy at/below this is noise floor, ignored |
||
hum_weight |
multiplier on (hum_energy - threshold) x 100 |
||
tone_ratio_threshold |
peak_ratio at/below this is normal content |
||
tone_weight |
multiplier on (peak_ratio - threshold) x 100 |
