Solar Choir
A ten-thousand-mirror solar array starts singing in tune.
When the heliostats of Array Field 4 begin tracking a harmony instead of the sun, a maintenance technician and a field acoustician have eleven days to work out what the array is aiming at.

Sound design — every person, action and object
- Nour Adeyemi — The array started singing four days ago. Nobody wrote the part.Field lav, no reflection at all, -23 LUFS
- Petr Havel — It's in tune. That is the problem.Boom at 1m, open-air
- • Open desert with a total absence of reflection
- • Wind between the mirror rows
- • Distant transformer at the tower base
- • Motor chorus, always present
The array is the choir — motor pitches harmonised into a real chord that resolves at the sweep's apex
Mix- • 5.1 and binaural stereo folds rendered from one bed
- • Dialogue -23 LUFS, trailer master -14 LUFS, true peak -1 dBTP
- • Every element is placed from its on-screen position and tracked as the camera moves
- • The motor chord is generated from each mirror's on-screen angle, so the harmony changes with the camera
- • No library loops on visible actions — each hit is cut to the frame it happens on
