One of the guys at work loves camping gadgets (as do I), and he shared a video of his odd little Mr. Heater camp stove making some weird unholy racket. Naturally, I asked to borrow it and did some recording sessions with it over the holidays.
A metal reflector lets the unit be used as either a heater or a camp stove. This ring of steel doesn’t make much sound when it’s running (all you hear is the hiss of gas emission, much like this recording), but it sure resonates when the stove fires up, starting as one tone and diverging into two separate tones, creating a harmony. Very effective or driving away bears, or as a means for summoning the dead.
The only processing applied to this sound is some noise reduction to minimize the gas regulator’s hiss, to pull the resonance forward. Recorded at 192kHz, a clip like this is ripe for pitch shifting for even scarier tones! (Mic placement was tricky; placing the mics right in front would melt them instantly.)
