Yes, I recorded audio in a bathroom. Draw what conclusions you like, you twisted little Intarweb Monkeys!
Sometimes, you need to record in embarrassing places to get the good stuff. A recent example for me was in a bathroom of a local supermarket.
Longtime readers and listeners to Noise Jockey know my obsession with cool drones. This one was an ancient, badly-needing-to-be-cleaned ventilation fan. It was really not that large, but it made this intense, deep thrumming sound that just had to be recorded. Luckily, no one came in while my recorder was rolling, presenting at best a challenging set of questions I’d have to answer…
[Note: This will be the last post you'll see on Noise Jockey using my battered and worn Zoom H2 Handy Recorder. It's been replaced with the Sony PCM-D50, which you'll be hearing more of this fall and winter! When the card and battery tray doors break off, and you've dented the mic grilles, and you've dropped it two dozen times, and its recording settings won't stick between sessions, it's time to just let go and upgrade...]
Think about it: Wound metal string under tension, wooden resonator. That’s all a guitar really is. What a wooden gate lacks is thickness, like a guitar, but at more than a meter in width and height, that’s a broad-enough surface to send air molecules running for cover.
I had to rosin the hell out of the bow to make it tacky enough to grip this oversized “string.” I found that also spreading rosin on the wrapped steel cable was helpful. I tuned the cable, as much as one can, by adjusting a turnbuckle.
I recorded in mid-side stereo. Today’s sample features is comprised of one mono track totally dry, one mono track run through Michael Norris’ Spectral Blurring effect, one mono track pitch-shifted down by 1.5 octaves, and the one stereo track pitch-shifted down by three octaves. Recording at 192Hz helps for such tomfoolery.
I apologize to my neighbhors for the unholy racket that I’m sure they thought was a demonic violin 101 class.

No sound designer can resist sound-making objects, so I did some recent damage at ThinkGeek for some small, inexpensive musical items…but then I noticed the robots.
However, I did get a tiny solar-powered grasshopper kit. An offset actuator in its abdomen makes the whole thing vibrate on tiny wire legs when it’s solar-cell carapace is hit with sunlight or a strong halogen source.
Of course, that would sound tiny and delicate. Which is OK. But how to make that sound bigger? Well, you put it on something that will resonate: Something with air around it that will conduct vibrations easily. (I’ve had loud, racous luck with this before.)
Being a hot, sunny Sunday, I chose the top of my closed Weber grill. I tested the sound with contact mics, but the steel was too thick. Truly, and unusually, where my ears were – close to the top of the grill – was where the best sound was. I switched to a hypercardioid mic in a windscreen, and captured today’s sound.
To accentuate the lovely low-mid resonant tones, I applied a huge -24dB cut at 5.5kHz , where the metallic feet where vibrating against the grill (I still wanted a tiny hint of chatter in there), tand a +9dB boost at 180Hz. Could make for a nice layer with some other design elements.

The smokestacks of the M.V. Tutoko, motoring towards the sea on Doubtful Sound, Fiordland National Park, South Island, New Zealand.
I went on an overnight cruise on Doubtful Sound on the M. V. Tutoko. Her diesel engines made a throbbing hum that I found enveloping, comforting, and even calming. I headed to the upper deck and recorded her at the exhaust stacks. It took a little EQ to get rid of the splashing water alongside, but this recording should give you a nice sense of the unique timbre and rhythm. Easily looped, this could absolutely make a cool vehicle sound (with granulation and dopplering), or a unique interior thrumming for a vehicle or mechanical interior.
