Andrew Spitz's new site, Social Sound Design, gathers great talent and attitude...a rare combo.
I’ve been using the new SocialSoundDesign.com for about a week or so, and I’m mighty impressed. It’s a strict Q&A format, but with some spiffy features. Most importantly, it’s got people way smarter than me involved, and I learn something every time I visit. (Ooh, plus it uses a fabulous red and black and white palette like another sound design website I could possibly mention. :-p)
While this is true of other forums (some of my faves are listed in the sidebar), so far SocialSoundDesign.com (SSD) has an extremely low signal-to-noise ratio of content to attitude. Everyone is giving with their knowledge. No one’s copping attitude. Questions range from the remedial to the advanced, and answers are informative and varied. It’s amazing to see many of the major sound design bloggers and active online professionals starting to gather in one place. It’s like a family barbeque for the Online Sound Clan…with very strange noises. Andrew Spitz deserves huge kudos for bringing this great resource to life.
As with any such website, the community is only as rich, giving, and patient as its members. If you’re interested in sound for film, games, and any other medium, it needs your voice. Check it out, register, follow it on Twitter for new-question updates, and join the conversation.
Horse hair, water, mic, and wok lid. Now we're cookin'!
My last post featured teensy finger cymbals being dipped in water while resonating, recorded with a submerged hydrophone. This time we go a bit bigger.
So, I played the wok lid with a violin bow as I moved it into and out of a tub of water, again with the trusty Aquarian H2a-XLR hydrophone tracking to a Sound Devices 702.  The H2a can be overly bright on some material, but for this stuff it was pretty good! (Next time I should record the above-water sound to a second channel with a small condenser mic for more mixing flexibility.)
The recording below is 100% unedited except for some slight compression and normalization.
Dipping struck finger cymbals into water creates some great filtering effects.
[Credit where credit’s due: This is a technique I’ve always wanted to try, and I first heard of it in a great video by Roger Gregg, at around 02:45. The entire series is worth watching.]
So a fellow gets a hydrophone. He’s excited, and starts recording all sorts of crap. But then he has a free hour to himself and realizes that he’s got a box full of sound-making toys and objects that could sound pretty interesting underwater.
Let’s say I’m that fellow.
Before work one day, I sifted through said toybox and decided to give this a whirl. In search for a large container to fill with water, I decided to record in the executive washroom of Noise Jockey World Headquarters, and the photos in this post will give you a glimpse of the sumptuous luxury in which we conduct our noisy business.
Since our high-tech executive spa didn’t have a stopper handy, I grabbed a plastic tub and filled it with lukewarm water. I put the hydrophone halfway between the surface of the water and the bottom of the tub, suspended from a boom arm so the cable would be isolated from noise and the mic element wouldn’t sit on the bottom.
An Aquarian H2-XLR hydrophone set into a tub of water.
The Aquarian H2a-XLR hydrophone is pretty heavy and holds quite still. One gotcha is that a high-frequency hiss can occur from air bubbles forming on the microphone casing. This can be a challenge if the water coming out of your spigot is highly aerated. I’m still working on solving that one.
I donned a pair of finger cymbals (truly something every sound recordist should own!) and dipped one or both of them in the water after striking them together. They went into the water at a 60°-90° angle, so that they’d not create entry splashes or secondary water drips. This created a really neat tone that combined a pitch bend with a very resonant filter cutoff.
I’ve attached an edit of the raw recordings to this post. Pitch-bent down or up, obviously, there’s a lot of sonic possibilities for sound design. As with all such experiments I do, I tracked at 192kHz to ensure enough latitude for further sonic malfeasance.
Hydrophone + Ice + Tonic. Sound and cocktail design in one easy step.
The latest addition to my microphone quiver is the Aquarian H2a-XLR hydrophone. For less than US$200, you get a really well-built unit with a high specific gravity (less sway in moving water) and a thin, flexible cable with an extremely supple “hand.”
I also got the rubber cup that enables it to be used as a contact microphone, and I must say that it also excels in this capacity: Super-low noise and very articulate, even recording human heartbeats with clarity (Hint: Aim for the sternum, the pecs have too much muscle and fat in the way). The H2a’s weight, however, prevents it from being easily taped upside-down or held in odd positions like my other contact mics I’ve used inpreviousposts.
I can’t hope to improve upon Darren Blondin’s excellent review of the Aquarian H2a, so in the short term, I’ll instead offer some quick and dirty recording results with it, with perhaps some more detailed results and analyses in the future. (Oh yes, some very strange recordings to come…)
When the H2a came in, I placed this device in all the usual places you’d expect for some quick tests: the sink, the bathtub, the cats’ water fountain. But having just discovered some very tasty tonic water for making cocktails, it struck me that I’d not recorded carbonation before. After hearing the clear, but not overly-bright, tones of the carbonation, I decided to mix up the room-temperature tonic water with some ice cubes.
The ice’s cracking, melting, and expansion was largely in the same frequency neighborhood as the carbonation bubbles and added an interesting dimension to the sound. Some initial sound processing makes me think that melting ice in still water might make for a cool creature sound pitched down -3 octaves or so, but for today, let’s listen to the original recording, unadorned and unprocessed.
This wasn't the helicopter I recorded. This is just the only photo of a helicopter I've ever taken! (Shot on the Kaikoura Peninsula, South Island, New Zealand.)
Audio professionals may cringe when they hear this, but I always keep a microphone mounted in my windscreen/blimp/zeppelin, which is always on a short boom pole. No doubt I’ll pay the price when the little mic suspension’s rubber bands stretch and age prematurely, but I like to be prepared for those unexpected moments.
This paid off when I heard a helicopter over my house…much lower and louder than usual. I poked my head outside and could tell the pilot was going in very tight circles over my street. I grabbed my mic rig and my field recorder, and all I had to do was plug in, power up, and hit “Record.” Granted, I happened to have a stereo mic in my windscreen, which wouldn’t have been my ideal choice, but I’d rather use it rather than lose the recording! (Want a horribly embarrassing tale about losing a choice recording opportunity? Read the epilogue after this post’s sound recording.)
I don’t exactly live in a city center, so I’ve got both highway and bird noise polluting most of my backyard recordings. This time, though, the helicopter was so low that the highway was drowned out, and he circled enough times that I was able to do some splicing of the takes to eliminate most of the birdsong. EQ could remove the rest, but I didn’t want to lose the higher-frequency sizzle that I liked in the recording. I did some surgery to make it loop seamlessly, and the result is below.
Epilogue and cautionary tale: I was at a hut on the Kepler Track in New Zealand when a helicopter landed on a nearby pad to drop off some fellow trampers/hikers who were “heli-hiking.” I scrambled for the Zoom H2 in my pack. Through the headphones, the sound was loud, intense, perfectly overwhelming what tiny background noise there might have been. I listened to the chopper landing, idling, and taking off. And then I realized I was only monitoring the entire event, not actually recording. The H2 requires one press of the Record button to arm recording mode, and another press to actually get rolling (a common interface convention in most hand-held recorders). In the moment, I lost track of how many button presses I did, and my fuzzy windscreen prevented me from seeing the time -elapsed readout, which of course wasn’t moving. What is there to learn from this, besides that I’m a complete spastic loser?
Never assume anything. Triple check everything, even if you’re going to introduce handling noise or off-axis sound into the beginning of your recording. Better to have a shorter recording than none.
Gear that’s always in record mode when it’s on is good, gear that audibly gives you feedback when you’re rolling is better, and gear whose display isn’t concealed by necessary accessories is best.
(P.S. The title of this post refers not to what I saw, but the song “Unmarked Helicopters” by Soul Coughing, which has been playing in my head ever since I made this recording. Damn you, catchy melodies, damn yoooouuuu!)
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.
Portage Bay on the Queen Charlotte Sound, South Island, New Zealand.
This will be the first of several posts that highlight some interesting sounds that I gathered from the South Island of New Zealand, from December 2009 to January 2010. Big thanks to Tim Prebble and others for offering advice!
I walked the 71km Queen Charlotte Track with my photo gear and my beat-up Zoom H2, and gathered quite a bit of sound over the 3.5 days I spent hiking. The last morning I awoke early to this unusual dawn chorus of birds…the more I listen to it, it might just be a handful of birds or even just one loud one, with echos coming off the walls of the surrounding hills. It sounded synthesized to me, like an ambient song. Give it a listen below, with some occasional post-rain water drips falling from the trees. (While this is unprocessed, I applied some spectral processing to it and it sounded like it came out of Avatar…may share that later on…)
[UPDATE: Reader Tom Williams from Devon, UK correctly identified this as the call of the tui. Thanks, Tom!]
This Mordor-looking photo shows Mono Pass in California’s Sierra Nevada mountain range. 12,000’/3,657m high, we crossed it in August, but we still got snowed, rained, and hailed on, and the winds were definitely in the 40mph range. A forbidding place, an intense day, and freakin’ cold to boot.
I remember the sound of the wind, especially, howling in my ears but also sometimes between spaces between rocks. Very distinctive, almost like the wind that you hear in movies.
I had to travel almost halfway around the world to a cute cottage in a summery, temperate rainforest to actually record wind that sounded like that.
Staying at a lodge along New Zealand’s Queen Charlotte Track on the South Island, a huge southerly wind kicked up around dusk and made this great whistling sound through our bedroom windows. What luck! Rather than be outside in an actual gale, I could position my recorder right near the sound source – tiny gaps between the windows – while having the windows themselves completely protect the microphones from the wind itself. I changed the perspective of the recording a few times, so rather than futz with it all to match or mess with a multitrack edit for this post, I just crossfaded to silence between each wind gust. You’ll get the idea.
So, just goes to show you: What you record, when, and where, can sometimes have little to do with the mental images one gets from the sounds recorded…which is why I included the photo above and not the nice real picture of tree ferns and sunshine!
This remote antenna array provided surprising sonic opportunities...as well as a hell of a workout getting to it...and an embarassment of forgetting some important pieces of gear...
There’s a small antenna array on a ridge near where I live (just above Skywalker Sound, oddly enough) that, like the ruined truck from a previous post, calls to me whenever I run or bike by it. It’s a 2.5, all-uphill, 1000′ climb to get there, but one foggy morning I decided to pack up some gear and run up there to see what sounds it might have to offer. Might the guy wires securing the short tower be taught and fun to strike? Might they sing in the wind? Maybe just a weird hum?
The infamous San Francisco Bay fog was thick that day, and I could barely find the faint side trail to the damn thing. Getting there, I realized that forgot my full-length audio cable (I was under-caffeinated and in a hurry to hit the trail). I’m there with a small-diaphragm cardioid condenser mic and a 12″ cable I usually use in my pistol grip shockmount, holding them with arms all bent and gimpy like a T-Rex. Quite a sight. The wind kicked up to about 15 mph, and I also forgot the fuzzy covering for my windscreen (a Rycote Baby Ball Gag). I wound up putting the windscreen right on the wires, mostly so that my body to shield the mic from the wind. This wound up transmitting both air and physical vibrations that radically broadened the frequency range of the recording, acting as a condenser and contact mic at the same time. Wound up being kind of a neat trick!
I got a lot of material in about 30 minutes of recording, some of which I’ll post later. But what was really neat was just holding the mic against the wires while the wind blew. Today’s sound is a drone taken from those wires humming in the wind.
I looped several pieces and ran it through a subtle spectral blurring plugin, which wound up augmenting some of the metallic, drony ringing tones in the original material. I just thought it was a bit creepy, otherworldly, and not at all what I expected to come away with!
I'm now the proud owner of an NJ-1 Heavy Lifting Utility Unit!
I’m very excited to share a new audio recording: The first steps of my new NJ-1 Heavy Lifting Utility Unit (HLUU). The HLUU is a do-everything kind of robot, and I’m hoping to use it for landscaping and home improvement projects. It was a big purchase in a pretty down economy, but my significant other and I think it’s a solid long-term investment.
I was so excited that I had to grab my field recorder and document its first steps. The manual says to let it charge overnight and then calibrate its voice command recognition system, but I just couldn’t wait to just let ‘er rip. Unfortunately, that meant that it only took a few steps before losing power and automatically shutting down, so that’s why this clip is so short.
This puts my Roomba to shame. Check out the recording below and say hello to HLUU!
