The Big Machines collection consists of 43 stereo recordings of 12 rare, industrial machines used many decades ago in German power plants and industrial sites. It includes the sounds of massive 10KV power switches, a Siemens exciter machine (power generator) built in 1945 and many other vintage machines. All machines were recorded in isolation without background noise and at high sample rates (192 kHz / 24 bit) with a Sound Devices 633 recorder and the Sennheiser MKH 8040 Microphones in close ORTF, taking full advantage of the extended frequency range (30 – 50000 Hz) of the microphones. Some machines were additionally recorded with a stereo setup of Barcus Berry 4000 series contact mics.
