We all know sound occurs through the vibration of air molecules, but what happens when you deliberately manipulate the pressure? We've employed a vast range of devices for exactly that purpose:
a five ton steam engine, an air compressor with many different attachments, truck air brakes, a domestic pressure cooker, spray cans, fire extinguishers, balloons, shaken up soda cans, paint ball guns & the most essential device of all; the human breath!
Every one of these devices provides a unique source of design material, whether its many varied forms of aggressive attack, or the sustained shriek & decay as the pressure drops… Use these as elements in their own right or convolve them with your favourite source material or impulse responses – the noise component means they cut through even the densest mixes. We also took the opportunity to record some very interesting ambiences – air hissing through a variety of pipes…
