It is what is says, people! ;-) I ducked out some handling noise, but for the most part the audio is unaltered. Enjoy.

Use gear made by those who make gear they themselves use, and make gear for other users. That's prosumerism.

The title of this article isn’t what you think it is.

You can’t shop for electronics or technology without hearing “prosumer.” People assume this portmanteau is a contraction of “professional-consumer.” Only marketing wonks have made it so.

That is neither its original meaning, nor the topic of this post.

The term was coined in Alvin Toffler’s seminal book Future Shock as a contraction of “producer” and “consumer,” predicting the merging of the roles of consumption and production into the life of one individual, primarily due to customization of mass-produced objects and the creation of highly specialized products. That is, person A makes widget X, who sells X to person B who makes widget Y, which person A, in turn, buys…it’s a massively networked set of cottage industries. This trend has exploded in the last decade. When Wired writes about micro-manufacturing and “no more factories,” we’ve probably arrived at a prosumer tipping point.

That, dear friends, is what this post is about. And yes, this is audio-related. Chances are, this article is probably about you, too.

Prosumerism: Why Now?

The growth of this trend can be largely attributed to the Internet and economic globalization for increasing individual access to tools, techniques, and materials. Things may be designed anywhere, be manufactured in the same factories that major brands use, and shipped anywhere…if it’s even a physical product at all. A prosumer can build pro-level anything in his or her own home by ordering parts from anywhere in the world.

If you doubt that we’re in the era of the Tofflerian prosumer, one need look no further than two trends: The proliferation of products that can be customized online, and the increase in cottage industries – often just one person – making technically advanced or unique products for niche markets that compete in every way with mass-produced products. Even if you’re not into Marxist theory, this shift has interesting implications for those of us who use audio hardware and software.

Prosumerism in the World of Audio

ZVex pedals and Livewire synth modules.

Let’s look at those two big themes as they pertain to the world of pro audio: Mass customization and the creation of niche/unique products.

First, “mass customization” is common in the world of audio hardware. There’s Michael Joly, who modifies cult-favorite Oktava MK-012 microphones to make them lower-noise and with better frequency characteristics. The well-known Oade Brothers who modify off-the-shelf, mid-level (the marketeer’s “prosumer” range!) audio recorders to produce lower-noise results with better dynamic range that compete with higher-end professional units.

Next, consider those who basically create gear for themselves, and then wind up turning that into a business to sell those products to others like them. You have Robb Nichols from Aquarian Audio, producing some of the best-quality, low-cost hydrophones out there. Dan Dugan of San Francisco makes automatic mixers used by huge networks in his one-room (albeit massive) workshop. Musicians make their own audio hardware, like the insane effects pedals Zachary Vex, and the analogue synth modules of Mike Brown (Livewire), Tony of MakeNoise, and Scott “Harvestman” Jaeger.

This doesn’t apply to just hardware! Shareware is made by individuals, to say nothing of audio plug-ins. Most apropos to this site, individuals like Chuck Russom and Tim Prebble, who use sound effects for a living as sound designers, create sound effects for other sound designers, bucking the aggregate-effects-house business model. I’d not be surprised if each of them will wind up purchasing each other’s effects collections…the ultimate in prosumerism.

The Benefits

What I think is most interesting and exciting, though, is it puts the users of this equipment into direct contact with the manufacturer. No marketing layers to penetrate, no call centers to deal with, no email-only front-line tech support. I don’t know how many of us take advantage of this, but it’s an amazing experience. The consumer directly can influence the producer by providing feedback, or even just doing something unique with the product that the producer never intended, and letting them know about it.

So…what’s all this got to do with you?

1. I know that some of my readers are these people I’m describing, so consider this the longest thank-you letter you’ll ever get for the killer products and amazing customer service.
2. If you use these products, close the loop. Call or email the Makers of Your Things and tell them what’s great, what sucks, how it can be improved, and what you’re using it for. Otherwise they produce things that get sent into an abyss, and I suspect that’s not what they want to do. They want to make things for people, not widgets that fly off the shelves for the absolute lowest cost. It’s about relationships.(Their attention to detail also can make for better products.)
3. If you’ve been wary about small-batch, hand-made products, that’s OK…and smart. But do some research and ask around, and you’ll find that there are a lot of very experienced and smart people out there making solid products. BUY FROM THEM. It stokes the independent spirit and gets money into the hands of the makers, not the sales department or marketing team.
4. If you’re interested in electronics or make things for yourself, get online and talk about it. The law of averages would suggest that you’re probably solving someone else’s problem, too.

Be a part of the greater ecosystem and community of products, or make some of your own. You’ll be all the richer for it.

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.

Bowed cymbals are one of the classic clichéd horror movie sounds…clichéd because they’re awesome! (coincidentally, just yesterday, Chuck Russom posted some great examples on his blog.) I recorded some a while back, borrowing some cymbals from a friend at work who keeps his drum kit at work. During that session I also realized that the wok lid from my kitchen made similar sounds, but with a different timbre: More groany, throaty, less musical, but with a quality I liked.

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.

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 in previous posts.

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.
