The Nexto DI NVS1501 is a burly, professional, and pricey way to back up flash media in the field without a host computer.

There aren’t many options available for in-the-field, no-computer backups for those of us recording to flash media, like Compact Flash cards, Memory Sticks, and SDHC cards. The most readily-available solutions are usually oriented towards photographers, focusing more on being digital photo albums than professional devices that makes our data more secure, and sometimes only accept JPGs, not arbitrary file types (like, oh, say, .wav files). Some devices, like the Sound Devices 700 series field recorders, will let you write to two pieces of media at once, but what about trips so long that you might need to reclaim CF card space? Or the other devices that we bring with us, like cameras, which can’t do that? Or the majority of trips that I take where carrying a laptop is more hassle or risk than it’s worth?

Portrait of the Artist as an IT Professional
Artists, designers, composers, mixers, and audio folks of all stripes must be conversant with the tools of their trade, and in this digital world, that means playing some role in managing hardware and software. This is where your hard-won creative output of blood, bits, and tears will be stored…and possibly lost.
This article is meant to help frame the challenge of selecting hard drives for one’s own home studio. I’m no IT professional, but I’ve been dealing with digital multimedia production for nearly 20 years, so I’ve at least got some perspective as a creative professional. I’ve seen my share of hard drives literally catch fire, glitch out, play the national anthem, and just simply stop working, sometimes one a day for three days in a row. I’ve had to manage IT issues from single machines to small clusters to an entire small studio. What follows, then, is what home-studio creatives of all stripes should consider when thinking about storing their creative output on hard drives.
Pipes along the side of the road. This is the kind of "a-ha!" or "ooh!" moment recordists wait for!
[Just had to post something orange and slightly eerie. Happy Halloween, all!]
It was a quiet night in a San Francisco warehouse district: Calm wind, not a lot of people on the streets, the sun was going down. A bunch of pipes – probably for redoing water lines beneath the street – were stacked on the sidewalk, perpendicular to the street.
This is precisely the reason that I carry a small, handheld field recorder with me at all times. I shoved it into a few pipes to check out what I could hear. I got some really nice drones with that added pipe/tube resonance and comb filtering, which will definitely go in my growing and rather extensive “unsettling drone” library. Some of the car passbys in the street had a resonant, screaming quality, which may make good spaceship pass-bys as well, or aggressive layers for expressive car ‘bys.
But, I quite liked some of the passages where this drone mixed with the activity of the street. Today’s sound is recorded within a 12″ diameter concrete pipe about six feet long. A lone man walks down the street singing, followed by a bicycle, he continues singing then crosses the street in front of me, a breath of wind really amps up the resonance for a moment, and then a few cars pass by, kicking up loose asphalt. Although it sounds like a mix of street noise with a synth drone underneath it, this is unedited except for some compression and normalization. The imaging is incredibly tight because there was about six feet of 12″ pipe in front of the mic capsules, narrowing the stereo field.
The general public knows of parabolics mostly from seeing people use them on the sidelines of sporting events. In nature recording, they’re for capturing species-specific sounds rather than ambiences. This is because the microphones in parabolic dishes are mono, and have sound pushed into them by the dish itself. This creates a very narrow “beam” of listening. Perceptually, parabolics seem like they “zoom in” on sounds, but this is simply due to such microphones just attenuating all the sounds outside that narrow cone.
Parabolics are also interesting because the frequency response is directly tied to the size of the dish. For most song birds, this is fine. Besides, making and transporting a 17-meter-wide dish just to get a 20Hz-20kHz frequency response just seems silly. At that point, you’re practically into SETI territory! :-)
I got the chance to use one at the Nature Sounds SocietyField Workshop. The unit you see in the photo above was the one used by the founder of the NSS, Paul Matzner, so I was holding a bit of history: Hand-made of fiberglass and aluminum, the NSS archives have lots of photos with Matzner holding this thing. Had I looked at the archives before heading into the field, I’d have gotten a way better handling technique. Holding it by its edges introduced horrendous amounts of handling noise.
Today’s sound is from this unit, recorded at 5:01am at Yuba Pass, off California Route 49. As far as I can tell, this is a chestnut-backed chickadee. You can tell, even in this recording, he’s got a lot of pals around (woodpeckers and sparrows at least).

Neither dirt, nor fog, nor clouds of mosquitos keeps a field recordist from his crack-of-dawn tasks!
I’m finally unpacked and rested from the inspiring (and exhausting) 26th Annual Nature Sounds SocietyField Workshop in California’s Sierra Nevada. Since my last post was a compilation of high-level personal experiences, I thought that I’d report back about what worked, or didn’t work, in the field on the technology side of things…as well as share a recording from our first early-morning field session.
Outdoor Gear. My REI trail stool was instrumental in keeping my body still (I can be a fidgety so-and-so), the importance of which can’t be understated when your preamp gain is at 80% of maximum and you can hear birds’ wing flaps 20 meters away. [Hint: For nature recording, more layers of softer materials - like fleece, soft-handed polyester, and wool - are the best for staying warm and silent. Consider gaffer-taping your metal zippers, too!]
Microphones. My primary MKH 50/30 rig performed brilliantly, with a strong signal-to-noise ratio even in the quietest moments. I also got a chance to try out a rather large parabolic microphone…more on that in a later post. [Hint: If you want a mic for nature recording, you need to be looking in the <-16dBA self-noise range, the lower the better.]
Recorders. The ol’ 702 worked its usual wonders. I monitored as mid-side in the field, only converting to left/right once I returned. A +8dB side signal using Tom Erbe’s +Matrix plug-in made for a wide, enveloping sense of space without losing center imaging. [Hint: Batteries drain faster when cold. Store spares inside your jacket, or in your sleeping bag with you overnight!]
The gear list across everyone was pretty insane: many Olympus LS10 recorders, several Sound Devices 744T’s, a Sony PCM-D50, and mics from DPA, Neumann, Røde, Sennheiser, and Telinga. Recording techniques varied from mono to mid-side stereo, XY stereo, ORTF, Jecklin discs, and even two binaural dummy-head rigs (see this site for a good explanation of all this alphabet soup). An outdoor mic directionality seminar helped to illustrate what each is good for, which was a rare opportunity and extremely educational.
Yeah, yeah, whatever. But what did it sound like?
Today’s sound was recorded around 5:45am on a day with a slight breeze and scads of ground fog. The location was Sierra Valley, north of state route 49 in the Sierra Nevada. This recording includes at least swallows (cave or barn, I’m unsure), American bitterns, red-winged blackbirds, white-faced ibises, yellow-faced blackbirds, and a bullfrog, and certainly more that I can’t identify.
Get those headphones on and close your eyes…

I’m just back from the 26th Annual Nature Sounds SocietyField Workshop. I thought that I’d share some video diary entries that I shot with my new iPhone 4. As far as I know, this is the first time that video of this workshop has ever been seen online.
I’ll be sharing more of the learnings, experiences, and recordings in the coming weeks. For now, I hope you enjoy this set of dispatches from the field.
The European Starling is a common bird that yammers like a manic street preacher. They have a really varied voice, quite expressive for standard birdsong.
I recorded one in my backyard and found that the frequency content really held up well under creative processing (unlike the raspy, high-mid-peaked calls of crows). Today’s sample is a continuous utterance from a starling that’s been pitched down 800 cents and run through the GRM ToolsPitchAccum filter, which I just adore for thickening sounds in unusual ways.
For me, it’s evocative of an exotic or alien ecosystem, especially with those other weird R2-D2-like tones in the background…but, again, the vast majority of those tones are being made by a single Starling.

Thanks to SocialSoundDesign.com, I’ve discovered the joys of iZotope RX, an amazing noise reduction tool that has made real one of my hopes: To capture reasonably clean sounds in my own back yard. I live pretty close to a major highway, so getting usable recordings has been impossible up until recently.
A neighbor’s willow tree harbors a very chatty and schizophrenic-sounding European Starling. While recording some of its yammering, a crow flew in, circled over me three or four times not more than 20 feet overhead, and then left, as if to warn me that I was too close to the community tree in Birdsville. I tracked him with my mic as he flew. Well, after that, I packed it in. It wasn’t going to get better than that.
The sounds of the background are still there, of course, but much less prominently than they were. The crow was close enough and I tracked accurately enough that while there’s a volume dropoff, there’s not a lot of apparent Dopplering. The caws are fairly shrill, so don’t turn this up too loud. (Note: From a sound design standpoint, pitch shifting crow vocalizations down doesn’t sound that interesting. They sound like asthmatic dogs coughing up a cat’s hairball, and not in a good way.)

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.
