Hand-built for drone-y aggression.
I love handmade soundmaking devices, but outside of my beloved Grendel Drone Commander, a lot of the weird noise boxes and effects I have are, well, noisy. They tend to be aggressive, loud, and blippy. Some accept MIDI, some accept CV, some accept no sync signal at all.
One evening I wondered if I could coax them into some semblance of ambient drones, to loosen myself up and not record to a fixed tempo, and to not get too “precious” with editing in post. Somehow the angry nature of these devices just seems to bleed through anyway. Or is that my angry nature?
So, the result of this cathartic experiment was “angry ambient.” Or, angrient.
This track features the following:
- All takes recorded live into Logic Pro X: No sync to anything, no MIDI, no CV.
- One track of a Bleep Labs Nebulophone, with its alligator clip clamped onto a key for a sustained drone, recorded through a Red Panda Particle pedal set to Reverse, both tweaked live. The dry and effected track were tracked simultaneously.
- Another droned Nebulophone track went through the Particle set to Delay, and then through a Seppuku Memory Loss pedal, with its clean microchip inserted, all three tweaked live. The dry and effected track were tracked simultaneously.
- One track of the RareWaves Grendel Drone Commander, recorded 100% dry. That thing needs no love, especially when its bandpass filters gets overdriven at low frequencies. Yummy.
- One track of the Bleep Labs Bleep Drum, played live in Noise mode, but then run through Glitchmachines’ Fracture plugin first, and the Michael Norris Spectral Partial Glide filter. That’s what generates the bright, granulated shimmers. These are the only digital effects plugins on any channel.
- Volume automation was done in one pass, “live.”
- The whole thing is run through U-He’s Satin tape emulator plugin for some additional harmonics and mid-high sweetening.
It is what it is.

Sometimes sound design requires thinking inside of multiple boxes.
I’ve developed a small collection of handmade and boutique electronic effects and instruments over the years, like the Grendel Drone Commander, Lite2 Sound PX, and many more (perhaps the subject of another post). Longtime readers may recall that I just love supporting independent makers and small cottage industries: That’s where all the weird, truly innovative stuff happens, and I (like many of you, dear readers) am more interested in cool sound design possibilities than straight-up distorted guitarrrrrrrr sounds.
Beyond this, I’ve also been expanding my collection of effects pedals. My latest three are definitely the weirdest: The Great Destroyer and Robot Devil from Dwarfcraft Devices, and the Wow & Flutter from Snazzy FX.

Rare Waves’ Lite2Sound PX, by Eric Archer: A photonic microphone!
I’ve previously written about the heavily-built, wickedly cool Grendel Drone Commander synth from Eric Archer. I check his site, Rare Waves, from time to time for new handmade electronic toys, and I was really intrigued by his newer Lite2Sound PX unit. This small device, in Eric’s words, “extracts audio from ambient light.” It’s a photodiode amplifier. Or a photosensitive microphone. Point it at light, it makes sound. It runs off a 9-volt battery, has a volume control, and a headphone jack. Simple, exciting, and a whole new world of sonic insanity. You can buy them as kits or, as I did, fully assembled.
Sounds pretty straightforward. If you just point it at bright, broad light sources, it’s kind of disappointing. It’s when you start listening to artificial lights in otherwise dim environments that some serious magic starts to happen. My experiments were conducted in and around high tech computer equipment, running an 1/8″ mini jack from the headphone output into my Sony PCM -D50 recorder.
Lights inside of PCs, modulated by fans…and further modulated by speaker grills as I passed the Lite2Sound from side to side. Ethernet network activity lights. Server disk access indicator lights. A close up of the power button of an XBox 360 while booting up. Pulsing lights of devices in standby mode. Halogen lamps behind spinning desk fans.
Lightly armored for future fieldwork!
The resulting sounds were astounding in their range: Static, glitches, distorted synth pads, pure sinewave tones, sawtooth-like tones, and much more. You can’t control it, really. It’s a tool of discovery, and its very nature encourages constant experimentation. It was so small and so perfectly complemented a handheld field recorder, I just wanted to take it everywhere and point it at everything! It imparted the same joy as when you start recording with contact microphones, or hydrophones: A new way to listen to the world around you. The more I used the Lite2Sound, I put it in a small plastic container (hacked with an XActo knife for access to controls and the headphone jack) in order to keep the components better protected.
Lite2Sound is a pretty narrowly-focused device and how useful it is to you depends on your taste for the unpredictable. Me, I adore this thing. Hell, I bought two (for future stereo photo-phonic insanity). It encourages constant experimentation, weighs nothing, and I can see using its output in both sound design and musical contexts. Eric Archer nails it again with an odd concept and a rock-solid, focused execution that results in a toy that just begs to be played with.

This thing was given to me as a Christmas gift. I immediately wanted to not froth milk with it, but to record it. With a hydrophone.
It was initially disappointing…until I put it into a metal pan and realized that its interaction with the pan, not the water, was far more interesting. The hydrophone was still in the water, but the frother was used in the water, inside the pan, and outside the pan as well, at varying speeds.

“Construction 129,” a never-completed gun emplacement overlooking the entrance of the Golden Gate, Fort Cronkhite, Marin Headlands, California.
When a winter storm was forecast for the San Francisco Bay Area, I decided to head to the Marin Headlands and try my luck recording bad weather in the abandoned gun emplacements and military fortifications of Fort Cronkhite. I had previously found some great metal sounds at Fort Baker, also in the Headlands, and I was also inspired by Tim Prebble’s high-wind-sub-bass-generator post.
Unfortunately for me, the storm track was slower than predicted, and I wasn’t able to record in peak wind, although some moderate rain started to fall. Such things happen, even with the best of intentions. So, what do you do when your primary plan doesn’t pan out? You reset your expectations and record what you can. I mean, c’mon, I’m in these amazingly evocative ruins! Surely there’s something that’s audibly interesting!
So, I decided to record rain in the tunnels. A recent re-viewing of Ridley Scott’s Prometheus reminded me that tunnels and caverns in films often feature water drops that are drenched in heavy reverb. I pressed the “record” button in several settings and closed my eyes: Was I in the bowels of an ancient spacecraft? The Mines of Moria? The hull of a leaky, empty freighter?
The gun emplacement at Construction 129. No weapon was ever installed.
Occasional wind blasts forced me to enable a high pass filter at 120Hz to try to remove some of the ambient rumble that didn’t help the recording. In addition, there are no fewer than three foghorns in the Marin Headlands, so I had to make an edit every 50 seconds to eliminate the lonely bleat of the Point Bonita lighthouse horn.
There is always something worth recording. You just need to let your disappointment go, reset your expectations with some beginner’s mind, and just start rolling.

The Uptown, Mission District, San Francisco. Photo source unknown.
The Uptown is the closest bar to my office, and is a classic Mission District hipster dive bar. One hot, Indian Summer day in the fall, it was filled with patrons, windows flung open…but the jukebox was off. And everyone was concentrated by the bar and front door, leaving the back area empty.
Anyone who tries to record diffuse crowd sounds, or “walla,” knows that this is a golden moment. Human voices, but little intelligible conversation, no background music, not too far away from the noise source. I ordered a beer, sat as far away from everyone as I could, and started rolling on my handheld recorder.
I did a little trickery by taking a segment of the recording, swapping the left and right channels, and layering it with another segment, to effectively double the number of people in the room. Luckily there wasn’t too much background noise to also get multiplied. Perhaps not the most interesting of moments on its own, but the little details of the cash register ring, squeaky door hinges, and the general density of the human sounds represents (to me, anyway) a surprisingly hard-to-capture scene without the intrusion of music.

Look carefully: Deep impact zone, short period, wind parallel to the shoreline. Not a good day for recording single waves. So...what is?
It’s easy to get recordings of roaring surf – which can often just sound like constant white noise – but it can be tough to get relatively clean recordings of individual waves. I’ve found that picking a good day and place to record single wave hits are a combination of marine forecasts and location, and that the size of the waves really doesn’t matter.
The only online article I’ve seen that mentions both field recording and marine forecasting has been published by Tim Prebble. In that excellent article, he describes finding gentle-surf days to record his amazing Seal Vocals SFX library. Sometimes finding those small- to moderate-swell days are sometimes the best days to record single wave crashes…but that’s not the only factor.
Single-wave recording conditions are largely defined by a mix of swell, wind, and location.
Swell is due to the large movements of water over great difference; swell is not the same as waves, which are usually wind-driven. Swell is usually forecast based on buoys offshore, and is forecast days in advance. However, I find that 2-day swell forecasts are the most accurate. Swell is defined by wavelength and amplitude, just like audio: Wavelength is is measured in seconds (usually called period), and amplitude (usually called height) is based in feet or meters. Ideally, you want swell with long periods, because that means there’s a greater volume of water moving, but tall swell is also your friend, because that also influences breaking-wave heights at the shore. (Tip: Waves come in “sets” of big and small, between 3 and 8 waves each, depending on if there are multiple wavetrains that are in or out of sync. That means record for far longer than you’d otherwise think in order to get a good range of big vs. small waves over time.)
Getting back to the topic of wind, not all wind is bad (and we all know what wind does to field recordings: huge amounts of badness.) Offshore winds (those that come off of the shore – yes, that is totally confusing!) will might wave faces up longer than they’d be up otherwise, causing a moment of quiet before the wave breaks (or “closes out,” in surf parlance) and a potentially taller wave face. Wind coming onshore (onto the shore from the water) often smears the wave tops and can cause premature toppling…not to mention the fact that the wind will be blowing directly at your microphone capsules. (Tip: You can’t be at the shore without shorebirds, often noisy ones. Bird feeding activity, and therefore noise, may peak before an oncoming storm. Watch the forecast and choose clear weeks with low-pressure days, when it requires more energy to fly, when possible to reduce avian noise. Gulls are complete bastards in this regard!)
Finally, this brings us to location. Some of this is taste: Do you want to record breaking waves against sand, or against rock? Very different sounds will come out of each; bigger crashes will happen on rocks as opposed to sand. But beyond that, know a bit about your location. What direction is the swell and wind coming from, relative to where you’ll be facing? How does the land curve around, creating refraction waves? What is the slant of the land below the shoreline? This last one is especially critical, as the gentler the slope, the bigger the wave. The “impact zone” – where the waves actually break – can be deep or narrow, and a narrower impact zone will generate fewer audible breaking waves at once. Knowing if a beach has a “dumping break” is useful: It makes it terrible to launch from or surf near, but that also means the waves break right at the shoreline, which is far better for audio recording. Just watch out for your gear. (Not a tip, but trivia: Waves always break when the water depth is 1.3x to 1.5x the wave height, as the horizontal energy of the swell gets forced upwards to create breaking-wave heights near shore.)
Never turn your back to the sea. The sea is huge, powerful, indifferent, and above all, unpredictable. Rogue and “sneaker” waves are not legends or myths: They occur regularly, anywhere in the world. Don’t let a recording session end in tragedy.
A final note on technique: If you’re on a beach, angle the mic a bit more downwards than you’d think would be wise, and you’ll get nice sounds of the sand being pulled back as the breaking waves recede back into the ocean. Not always good to have in every recording, but this adds a lot more character. On a beach with fist-sized rocks, this can be especially cool!
I had a recent session at a sandy beach in the Point Reyes National Seashore that exemplified some of the better (but not quite perfect) conditions that I describe above. First, the wind was blowing at 20 knots…but from the opposite direction of the beach I was on, which was backed by hills. That meant delayed wave breaks and being protected from the wind. There was a southerly swell that came right into the dumping-break beach (I can tell the period is averaging 14 seconds by looking at the waveforms of the audio!), so it was all breaking swell and no wind-driven waves. It was a low-pressure day with a long-term clear forecast, and it wasn’t winter, when the masses of migratory birds come through Northern California. Only one swallow’s call made it into the recording.
The recordings aren’t all that dramatic when you consider the breaking waves were only 3-4′ high. But listening to this loud on headphones, eyes closed, I find that the sense of scale is quite exaggerated without an accompanying visual reference…a little Waves LoAir or layering some low-frequency booms can definitely can tip it into cinematically-big breaker territory if desired. However, even in a 90-second clip, there are only three really distinct wave “claps” as the bigger waves close out at the beach.

My mecca on a foggy morning: Urban Ore!
I went to the granddaddy of thrift stores recently, so much so that it’s more of a glorified junk store…but oh, what glorious junk. I’m talking about Urban Ore in Berkeley, California. Sometimes I’m self-conscious shopping for things by ear, picking up random things and just listening to them, but at Urban Ore – heck, Berkeley in general – I can ear-shop in peace.
I was in a metallic mood, so I filled a bag with things that squeak, resonate, creak, clank, and sproing. Based on the dronetastic results of striking wire shelving last year, I picked up a few thin-wire metal grills that had sonic promise, among other things that will surely find their way to this blog later this fall and winter.
For the grills, I decided to trot out my much-neglected piezo contact microphones. The resonant notes were so subtle that it seemed like the best way to capture the sound at a reasonable volume. I plucked them, struck them, and played them with a cello bow. The magic happened, though, when I realized one was easily played with a bow and the other was not, so I stuck the bowable one inside of the other, and played away, causing both of them to resonate when played appropriately.
The results were like ultra-low-fi bastardizations of stringed instruments played in horror movies, and I just loved the character. The rawness of hearing the actual hairs of the bow on the metal, in my opinion, lends to the eerie charm.

Rusty? Heavy? Covered in graffiti? You KNOW it will sound good.
Many people are unaware that the San Francisco Bay Area was once thoroughly fortified against attacks from the sea. Remnants of this past dot the entrance to the Golden Gate, in the form of bunkers that once housed gun emplacements.
One such installation was Battery Yates at Fort Baker. Located at the best vantage point for southward-facing photos of the Golden Gate Bridge, Battery Yates was meant for nothing other than picking off minesweepers that might try to get through the minefields inside the ‘Gate in wartime…minesweepers, of course, that would never come.
Battery Yates was active from 1905 through 1946. Now, only the U.S. Coast Guard maintains a station at Fort Baker, primarily for saving the lives of boaters and wind/kitesurfers. Now Battery Yates is a tourist attraction, is fun to scramble on and around…and, in swords to ploughshares style, is also a great source for cool sounds!
Each of the gun emplacements has four lockers, each sealed with a massive steel door. Some doors have outer latches that have been left to swing freely in favor of just welding the doors shut. These latches, rusted by more than 60 years of salty mist, are quite expressive when swung, manipulated, and otherwise mishandled. The perfectly square concrete rooms behind these doors caused them to have a lot of low end and resonance.
I decided to try my luck with recording some groaning metal effects on these doors, despite the fact that:
- I only had some time before work one weekday, which meant that…
- I could only record during rush hour, made worse by the fact that…
- The Golden Gate Bridge is only 1/8 of a mile away, plainly visible from the recording site.
All this meant lots of background traffic noise. I mitigated these risks by using a hypercardioid microphone for off-axis rejection of sound (a shotgun would have been a better choice in terms of pattern, but I just loved the sound of my MKH-50 too much to not use it), careful placement of the mic relative to the bridge (making sure that either the mic element faced away from the bridge or a thick concrete wall blocked line of sight), and the judicious use of the Denoiser plugin from iZotope RX. And, for effects like these, the small-condenser-mic proximity effect only helps!
The result came out pretty well, all things considered…although the editing in today’s post is pretty sloppy, so apologies for that. Everything was recorded at 24-bit, 192-kHz, as best befits complex groaning metal sounds, since pitching this stuff down can yield pure sound-design gold. I recorded even more massive metal hits from this session, which may be a topic for a separate post… (And until then, you can hear yet more heavy metal hits/impacts here, here, and here.)

Eton Mine, Lucky Boy Trail, Joshua Tree National Park, California, USA.
[One in a series of posts from my spring 2011 trip to the southern California desert.]
Joshua Tree National Park is beautiful, but much of its history (prior to being designated a National Park) has scarred and pockmarked its landscape. In the Gold Rush, the Joshua Tree hinterlands held some of the most productive mines in California until well into the 1900′s. These mines were big, sprawling, and deep. To my knowledge, no Balrogs were released as a result. But that would explain a lot about Golden State politics.
We hiked on some lesser-traveled trails and found an acre of land with no fewer than five vertical holes in the ground: Mine shafts. They were all wired off and had metal grates over them. One in particular, the Eton Mine on the Lucky Boy trail, had warning signs on the wire fence surrounding it.
It was quite windy that day, and I just knew I had to get the creaking, squeaking sounds of this battered sign on the rusty wire. It took me a surprisingly long time to figure out how to protect my handheld recorder from the wind, but ultimately I decided to use my body as a shield and then stick it under my microfleece hoody. (I had the OEM fuzzy windscreen on it, which is one of the most useless strips of fabric I’ve ever seen, er, heard.) I just hoped that my body protected it from the 25+ mph wind gusts and that the fabric wouldn’t dampen the high frequencies too badly…and because of the sound, I had high-frequency content to burn.
With some judicious noise reduction in post – subtle, as always, gives the best result – it didn’t come out too shabby, considering the horrible recording conditions and super-no-budget wind blocking techniques!
