Whenever I move into a new place, I try to go through and record all the vents, doors, cabinets, and anything else that might make a noise. I recently unearthed a few recordings of some air ducts I did shortly after moving into my current place. Each vent has its own personality and some of them get REALLY loud. In the following clip, I moved the mic around to different locations within the airflow and then started tweaking the vent position to get different tones. There’s some really cool stuff…including me almost falling off the ladder at the beginning. Woohoo, I’m a klutz!

Nerd talk: I recorded this with a R0de NTG-3 and a Sennheiser MKH30 in M/S configuration into a Sound Devices 702.
