The restorer's note
The swept-sine rig that captured a room's impulse response — which is to say, a machine for taking spaces and playing through them. Point it at a hall, a cabinet, a piece of hardware, and keep the result. Measurement, quietly become convolution.

Demonstration recordings, prepared at the bench.
Room 04, as measured
The hits run dry for five seconds, then Mix rises to 50 % and Room 04 answers — four tenths of a second of measured space behind every strike. Mode stays on Convolve; nothing is embellished.

Plate 18, cut short
Plate 18 with Length at 45 % — the measured decay cut mid-fall, a gated read of the archive. Mix rises to 65 %; at twenty-two seconds the direct signal leaves and only the clipped plate remains.

Reversed, then measured
Chamber 11 played backwards — Reverse on, Tilt at +6 dB/oct, Pre-delay at 120 ms — every hit answered by a swell that builds instead of decays. At twenty-four seconds Mode switches to Measure and the Trigger fires the sweep: the instrument taking its own reading.
