Sure, it’s fun to use long, non-reverb sounds as impulse responses…but what about short, percussive ones?
Convolution reverbs have been a staple of audio post-production for a good while, but like most tools of any type, I prefer to force tools into unintentional uses.
While I am absolutely not the first person to use something other than an actual spatial, reverb-oriented impulse response – bowed cymbals are amazing impulse responses, by the way – I hadn’t really looked into using very short, percussive impulse responses until recently. I mean, it’s usually short percussive sounds you’re processing through the convolution reverb. I found that it can add an overtone to a sound that can be pretty unique. Try it sometime!
(Coincidentally, today Diego Stocco’s is promoting his excellent Rhythmic Convolutions, a whole collection of impulse responses meant for just these creative purposes. Go check it out!)
Today’s sample is in three parts. First, a very bland percussion track. Then, the sound of a rusty hinge dropped from about one foot onto a rubber mat, recorded with my trusty Sony PCM-D50 field recorder. Then, the same percussion track through Logic Pro’s Space Designer (Altiverb or any other convolution reverb will do, of course) using the dropped hinge sound as an impulse response. It adds a sort of distorted gated reverb, adding some grit, clank, and muscle to an otherwise pretty weak sound.

My past winter holiday involved a sea kayak crossing to Las Islas de Los Todos Santos, a pair of islands four nautical miles offshore of Ensenada, México. We were greeted – and partied with – a nearly toothless lighthouse keeper, and slept in an old lighthouse built in the 1930′s.
We had two days of 15-25 knot winds, and as you might imagine, a lighthouse is a roughshod place. The winds were howling through the old windows and making amazing sounds.
Only one problem: I had a small sea kayak with no room to even pack a handheld field recorder. As I’ve said many times before, the best field recorder is the one you have with you, and this case, my only option was my iPhone. In glorious, shimmering mono.
Today’s sound are of these howling winds, recorded with the Voice Memos app on iOS. I’m not about to make a habit of using my iPhone as a field recorder, even with aftermarket microphones, but hopefully this goes to show that sometimes you do the best with what you have. Especially if the sounds and location are literally once-in-a-lifetime events.

BugBrand banana jack bonanza!
After getting to know the Tetrax Organ, profiled in my last post, I became interested in what other devices used banana jack interfaces for control voltage (CV) modulation. The eurorack standard for modular synthesis is wildly popular, but its buzz drowns out other equally interesting platforms, like the banana-based Buchla and Serge systems.
This research led me to BugBrand, a quirky English manufacturer of both modular synths and desktop formats (who also happens to be a top notch guy, not to be confused with The Bug, who I’ve been following since his first release in 1997, which is based on The Conversation, which is about a sound recordist…talk about circular references…). I had heard great things about, and from, his gear, especially a well-regarded but often-overlooked device called the DRM1 Major Drum. This filled a hole in my gear list: a dedicated all-analog, super-flexible drum synthesizer. And with a Tetrax Organ and a Low Gain Electronics UTL-1/2 format converter, I could easily drive it from pretty much any source that output CV.
Hell, it even came in red, like my beloved Grendel Drone Commander.
In short, I picked one up, and am thoroughly enjoying it. It mixes well with other gear, especially if I’m rolling all-analog. It overdrives naturally, aesthetically, and quickly, lending itself to aggressive styles, but not limited to them. I especially like the ability to create rising or falling triggered envelopes via the “Bend” feature. Having two trigger inputs (three if you include the big red button) and CV control of both its oscillator and filter are great. I do wish the filter was steeper for more extreme sculpting of the noise generator, but you do get the choice of bandpass or lowpass/highpass (the latter switchable with an internal jumper) via a front-panel switch.
In all my research, though, I never really came across a single piece of media that really dove into its sound design abilities. While its tone can be varied a little based on the strength of the trigger signal it’s fed, it’s a single-voice synth, and no video demo or Soundcloud track really seemed to express its breadth of sound design possibilities.
So, I decided to do something about it.
The sounds in today’s track are entirely made from the BugBrand DRM1. About half of the tracks are sequenced via the EHX 8-Step Program sequencer pedal (including the dubby melodic loop), and the rest are hand-edited, and one track features modulation form the Tetrax Organ’s touch pressure, and another using the Tetrax’s oscillators to drive the DRM1′s oscillator and filter. Effects include some delays, one reverb, and a bunch of high-pass and low-pass filters and EQ’s, with some compression on the output bus.
The sounds all have a very strong flavor, sharing a lot of timbral qualities, regardless of the function they serve in the mix. That can be good or bad, depending on what you’re after. But still, I think it’s impressive that this is all from a device with only one oscillator, one filter, and only three CV inputs. And this thing has a truly massive frequency range: its lowest pure tones drop to at least 20Hz, and it’s pretty easy to get spikes near or above 20kHz!
Pro tip: BugBrand products are tough to get a hold of, as Tom Bug doesn’t hold much inventory at any one time, so when he makes a production run, they sell out in a heartbeat. If you want to get in on Tom Bug’s next manufacturing runs/releases, get on his list.

A lush nest of sonic discomfort.
Following on my last post, I’ve continued to play around with my recordings of deer antlers through a contact microphone. Today’s sound is almost entirely from that session, with only a handful of synthesized sounds, all triggered by LFOs and other random modulations. The manipulations of the deer antler sounds were done in the very weird, pretty unstable, and utterly unique Gleetchlab application, as well as iZotope Iris, which did an amazing job of figuring out the root frequency of the flute-like and cello-like bowed resonances.

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.
