Rain on tin

Sessions

Forty-one sessions were recorded over two winters, mostly at dusk, under corrugated sheds and across a flat sheet roof on a cold store. Rain on tin depends on the gauge of the metal and on how much water is running off it, so each entry names the surface. The collection is the smallest of the three, and its files are the lightest to work with.

1. KA-R-003 Corrugated shed, light rain, no wind
   • Format: Broadcast WAV, 48 kHz, 24-bit, stereo
   • Size: 18 GB, 2 h 00 min
2. KA-R-012 Flat sheet roof, heavy rain, drumming
   • Format: 32-bit float, binaural, 96 kHz
   • Size: 96 GB, 3 h 40 min
   • Note: the drumming is loudest near the roof edge, so placement matters

   • Size: 44 GB, 1 h 55 min

Choosing a roof

Heavy rain on a flat sheet gives a dense, even drum that suits a bed under dialogue or a long establishing shot. Corrugated sheds are brighter and more rhythmic, with a ring from each ridge that carries well through a mix. Gutter files are the most specific, and they work best where a scene needs running water with a clear source. Editors who need a longer loop should use the flat sheet sessions, since the rain there changes least across a take.
