Adaptive Response
Response Sensitivity65%

How quickly the controller reacts to speech onsets and level changes.

Formant Bias Depth55%

How far synthetic formants are pulled toward the live detected F1/F2.

Max Adaptive Boost2.0×

Upper bound on closed-loop gain. Higher = more aggressive in loud rooms.

Masking Margin0 dB

Target masker level relative to speech per ERB band. 0 = equal level; +6 = masker 6 dB louder.

Synthesis Character
Base Grain Density50 g/s

Baseline rate of phonetic micro-bursts per second.

Syllable-Rate Mod Depth45%

AM of density/level at the tracked syllable rate (2–8 Hz) for envelope masking.

Consonants & Plosives60%

Transient /s/, /t/, /k/ bursts preceding vowel formants.

Sub-Bass Brown Bed40%

Deep low-frequency rumble to absorb door slams and footsteps.

Voice
Base Vocal Pitch (F₀)125 Hz

Baseline fundamental vocal cord pitch.

Base Master Volume55%

Baseline output before adaptive gain. Keep moderate to leave headroom.
