The Nexto DI NVS1501 is a burly, professional, and pricey way to back up flash media in the field without a host computer.
[Editorial note: This is an expression of my opinions about this piece of equipment. It was purchased and not provided by the manufacturer. I have no relationship with any company listed below.]
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?
There are lots of under-the-radar software toys out there for mangling audio, but one that I have yet to hear anyone really discuss much is Spongefork, created by Ryan Francesconi over a decade ago. It’s been around for a long time, and is intended as a live improvisation instrument. Its incredibly sparse interface belies a lot of sonic mangling possibilities, with multiple sample banks and a live-control XY controller. For $65, it’s a fun toy. (Even the demo fully works, just without the ability to save work.) Heck, I’ve used it so long that I upgraded when I made the move from Mac OS 9 to OS X!
Here’s a set of live tweaks to some sheet metal hits (recorded when we had a custom heat shield fabricated for our wood stove). In my library, when I see “forked” in a filename, I know it’s gonna get weird…

The home studio, circa summer 2011.
Following on my previous post, here’s how I break down data storage, redundancy, and backup in my own home studio. These strategies won’t work for everyone, but having tried lots of different configurations, this setup balances redundancy, backup, flexibility, speed, and most of all, cost. And, of course, this breakdown is only useful in the small home studio. Larger studios have totally different needs!

Bits and bytes are mighty tasty. How does one store them for maximum freshness?
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.
Hand-built one at a time by Eric Archer, the Grendel Drone Commander is a two-oscillator synth built inside of a metal surplus ammo box. Its apparent simplicity belies its sonic complexity. I’m still feeling my way around the thing, but I wanted to post an example of what it makes possible. (Next step: Play with CV control!)
This heavy, drone-y, smeary track was created using only the Grendel Drone Commander, recorded live thee times, each on a different track, in Logic Pro (with a few plug-ins as well).
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 thought it might be interesting to share what I’m bringing with me to this interesting outing. (Well, OK, fine, I really needed to make a packing list and I just suckered you into reading it.) Later this summer, I’ll not only share some recordings and photos from the field workshop, but will recap the gear used and how it all performed.
To paraphrase Ned Flanders, "That set my beatbox all the way up to Roomba!"
Lavalier microphones (“lavs”) are used with wireless transmitters and receivers all the time in the world of film and video production because, well, actors move. Sometimes it’s the best way to mic someone if you can’t keep up with their movement or a boom can’t get close enough, as with a wide shot. They’re not usually the first choice for miking talent, but they’re a common one and a good tool for certain conditions.
Wireless lavs are also handy in sound design for the same reason: Some things move. When they move, you need to pan your mic with it, or accept off-axis sound falloff, or be trying to get a Doppler effect. If you want your mic point-of-view to stay on something moving, and a cable’s going to get in the way, then a wireless mic system is just the ticket.
