To make this 4:15 minutes long recording I found a creaky spot on the wooden floors of my house, rocked back and forth in place and pointed a stereo mic at my feet. I remember doing this years ago, but thought I’d give it another go using a faster sampling rate and bit depth so the quality is not reduced as much when pitched down. Before making the recording I set the sampling rate and bit depth to 96kHz and 24 bit. I pitched it down two octaves and then normalized the results before rendering the final output.
I’ve suggested this technique on several occasions to students and sound designers to manufacture a realistic simulation of a creaking ship. It’s sounds as if I added reverb, but it’s just the natural sound of the room itself. I was not particularly careful about recording in a quiet environment. I heard a car go by outdoors at one point, but it’s not too noticeable after the down pitching.
Down Pitched Wood Floor Creaks
To create this sound I took the bubbles sound from yesterday and programmed it into a simple sampling VST. I built a pattern of chords in a MIDI clip that covered a wide range of frequencies for the sample simultaneously. This created a sort of spectrum of pitches. The next step was to spread that spectrum of pitches by resampling the output in a processor called Fragulator that effectively chops up the sample into fragments that can then be automatically looped at different frequencies. 
Ever get yelled at by your parents for blowing bubbles through your straw? Well, now it’s my job to blow bubbles through a straw. For this recording I blew bubbles in a glass of water (not Guinness as the photo suggests) while recording the results. I used this sound to create the underwater atmosphere for Aaron Dabelow’s 3D animated short, “Drown”. You can hear the pitched and processed version in the post, 
I have yet to use this recording for anything. I made it about a year ago when I was working on the sound design for a 3D animated short. It was one of many sounds that didn’t make the cut, but still has an interesting characteristic or two. We’re all familiar with the sheet metal wobble. The plastic mat wobble is similar, but with less racket and a sort of low frequency rubbery quality. I must have been holding my breath during the recording because you can hear me breathe in deeply at the end.
Here’s another sound that I would label as “Pro-One Dub”. I guess all that really means is knob turning and delay, but when you get good results with this instrument you know it. I love the fact that you cannot store presets on old analog gear. It makes you create a new sound every time you turn it on. I had the knobs in a pretty good position to start this time, but after a few more adjustments I got this great modulated effect with the LFO near top speed and at maximum amount. Just tapping a key gave me this nice squirty raygun effect, so I dropped that in the track before getting my sound for the melodic line I needed for the piece. Here’s a chunk of it pitched down a bit and running through a short delay with lots of feedback to create a vintage raygun effect.
