Colour's doctrine, transposed: a sound system that cannot fail an audibility check does not have one. The check is a MARGIN over the floor.no extension

(no comment in the source: the name reads as a sentence) declared floorno extension

The margin now uses LoudnessOfSupport: the SAME K-weighting and the same -0.691 + 10log10(z) formula, over the sound's own length. It is not a standard LUFS figure and the metric name says so -- but it is the ear's own weighting rather than a flat average, which is the difference between a gate that models hearing and one that models arithmetic.no extension

The gate. A cue needs 10 LU of headroom over the room; an alert needs 20.no extension

THE DECISION IS A PURE FUNCTION of (state, meaning, now), so a guard can assert the contract on a machine with no audio device at all. Fire() calls exactly this, with the transport's clock.no extension

The state advance, separated from the decision so both the real path and a device-less guard drive the same code.no extension

COUNTED, like everything else this plane does behind a listener's back. "Why did that get quiet" must have an answer that is a number.no extension

The gain the RENDER is applying to a value's bus right now. During a ramp this is somewhere between the old value and the target, which is what lets a guard prove the ramp MOVES rather than jumps.no extension

Duck every value QUIETER IN MEANING than this one, and leave the rest alone. Ramped, so it cannot click.no extension

Everything back to unity, on the same ramp. Restoring with a JUMP would click exactly as ducking with one would.no extension

VC4: SAY -- the earcon, then the phrase that says WHICH ------------- Which language the phrase is spoken in. REFUSED rather than substituted if the machine has no voice for it -- speaking French to an operator who asked for English is worse than saying nothing.no extension

Which language it is actually speaking -- empty until one is set and ACCEPTED, so a caller can tell "not asked yet" from "asked and refused".no extension

(no comment in the source: the name reads as a sentence) can speakno extension

Needs no audio device, which is what lets a guard measure the composition on a machine that cannot play it.no extension

Say it: the earcon, then the phrase. Queued, not played immediately -- call TickSpeech() (or SpeakQueueToEnd()) to advance.QCSXTZZZIBWU

One step. Starts the next phrase when nothing is speaking, and reaps the transport when it ends. Cheap; call it as often as you like.no extension

This method OCCUPIES THE THREAD. Nothing can call Say while it runs, so the queue it starts with is the queue it finishes with: there is nothing left to cancel, and rendering the whole of it into one buffer is not a loss of behaviour, only of churn. TickSpeech keeps the per-phrase transport precisely because a program that ticks CAN be interrupted, and there the ability to stop mid-sentence is the point.no extension

The silence between a cue and its phrase, and between two announcements when a queue drains as one. Exposed because a guard has to be able to account for it rather than assume it.no extension

What a caller must not assume. Haro occupancy plus the measured device and OS floor -- see plan S.5 for where each number comes from.no extension

Rule 18 allows 100 ms. This answers whether a sound can be the acknowledgement, and on this pipeline the answer is no.no extension
