SF Lunchwalk: Attack and Decay

Four Recent Lunchwalks

Attack and Decay are technical terms known to sound editors and synth musicians, but the concept is also intrinsic to urban walking.  "Attack" is the initial rise of a particular sound and "Decay" is the falling away of the sound from its peak to a normal or "sustained" volume.   Doors open and the clamor of a restaurant rushes out (attack); someone walks in, shutting the door behind them (decay) but listening closely, the sound of the restaurant remains.

If we think of the city as an infinite sound library, the library is perused by walking through it.  Sounds rise and fall and blend together in the great mixing chamber which is the street.  I am interested in the ability of the city to edit its own sound.  The sound-makers engage in the space of the street, all competing to vibrate air molecules.  Air is resilient; like a spring, it receives the initial burst of sound energy and then recoils (decays) until the sound disappears.

Since my last post with sound, I have recorded four hours of sound from four lunch-hour walks, continuing this series where I take a walk through the city instead of eating lunch.  Listening back through the sound recordings, I am pulled in two directions.  One, I have ideas to snip up the recording and reconstruct the walk as an edited soundscape.  The other direction is to isolate only certain moments where it appears as though the city has done the mixing for me.  This latter case is explored in the following track.  Listen:



The track is unedited.  It is simply what I (or the microphones) heard over a 2 minute time-span, using elements of the city (doors cracked open, hills, different sized streets) to "edit" the sound.

SF Lunchwalk: Smokestack

Walking every week, with every chance I get.  My feet vault me out of a sedentary habit (we are what we repeatedly do) into the unique opportunity of an urban walk, latent with unexpected encounters.  Encounters, such as the sight of this smokestack somewhere north of the lunch hour ground zero.  I marvel at its unlikely location, amid the housing and workplaces.  Surely it cannot still be in use.  Do its neighbors consider it a historic resource, a neighborhood landmark?  What if it is in use, but for a use not originally intended...

The smokestack is a non sequitur, a rather large and prominent form nestled within a residential, low-rise neighborhood.  Surely, some research would tell its story.  But the point is not to know where this smokestack came from or its historical use.  The lunchwalker on the go is all eyes and ears to the sidewalk unfolding beneath the feet; no time to research on a smartphone.  Even the excuse of wanting to just "be there" aside, there is more reason to disregard the histories of structures and spaces along the walk: the forms of the city are opened to fresh interpretation.

Ceci n'est pas un smokestack.  It is a vent for a vast subterranean vault.  A wind pipe for a geological organ.  An observation post to collect ambient neighborhood sound.  Let the city try and preserve all of its artifacts.  I can create and destroy them at will.

The lunchwalker embeds a set of desires unto a set of inert objects.  The set of desires is not alien to the walking environment, not fabricated beforehand, but generated along the walk, activated by the sounds present and alive there.

Do not walk to see what the city is.  Walk to see what the city can be.  Walk, to make the city anew.

SF Lunchwalk: Forty-three Ambient Slices of the City

Why even bother with the names of streets?  In a world of sound, the names of streets ring silent.  They are dwarfed by the din of traffic, overwhelmed by thousands of diffuse sounds from the city hulking above.  Market Street, for instance, beckons to be renamed every time I walk out onto it.  My feet are willing to forget, but my head still wants to know: where am I going today?

East.  The Lunchwalker needs not the guidance of familiar street names.  It's not as though these walks are to be repeated.  Nor could they be.  Tracing the footsteps of a previous day's walk is not possible.  (Although that would make a fascinating walk to attempt to do so, even memorizing the sounds as though scripted by iambic pentameter, and to recite and overlay the previous day's walk upon a new day's walk.)  The soundtrack on a given day, at the same time and with the same route, will capriciously yield an entirely different experience.  So I walk east, and I could walk east every day and still find new things to hear, new worlds of sound to discover even though the world we see appears much the same.

What is that funny thing about an urban walk which enables the feeling: "I've walked here many times and yet I've never seen that before."?  Getting lost in a familiar place is part of it.  We all read the street signs and use them to familiarize ourselves with our whereabouts and communicate to others our experiences there.  Practicality aside, the real advantage of an urban walk is ignoring precisely the need to communicate the location.  Streets should be named instead for the sounds one may hear on them.

I have provided this recurring satellite view of my walkable terrain, but I even question its value other than to give a sense of scale of the walk.  For example, the spaces which continue from the outside to the inside -- how are these sonic continuities to overcome the familiar delimiting of interiors and exteriors?  The satellite photo is blind to interiors and numb to the scale of individual sounds.

But there are unexpected relationships between quadrants of the island which in fact drive me to explore more every time I go out.  Deeper into the grain of the city, similarities between two different spaces in different moments of time could be knitted together by a precise framework.

The spaces of the city could be taxonomized by a host of sonic qualities: loudness, frequency range (Hz), frequency of occurance, breadth, height, reverb, diffuseness, velocity, proximity, timbre, fuzzyness, reproducibility, and even its inaudibility i.e. vibrations which are below the threshold of hearing.  These new names, not just for streets but for all thoroughfares and places for pause, might go this way:

Street of Cars Bowling for People
Garden of Circling Sparrows
Garden of Reverse Waterfalls
Sidewalk Spouting 700 Hz
Cranes Thumping Every 15 Seconds Alley
Muzak's Shortcut
The Street Where I Heard a Strange Bird but Maybe It Was a Machine


For this sixth Lunchwalk, I took 43 slices of sound out of the walk and glued the slices back together.  Each slice is potentially a new entry into the sonic taxonomy of the city.  Listen:

SF Lunchwalk: Taco Truck

On this fifth lunchwalk, where I take a walk instead of eating lunch, I broke the only rule: I ate lunch.  Two shrimp tacos, to be exact.  I also did not walk alone but wandered out with a friend, Marc Wiedenbaum of disquiet  fame.  Our walking discussion ranged across current projects of his, on the reasons we walk and listen, and, as we descended upon a taco truck, the sound of food.  So, here is a lunchwalk that was more of a walk to find lunch rather than a walk to capitalize on the time saved by not eating lunch.  (Indeed this series could be about walks to a constellation of food spots in the city not frequented by the Market Street workers.  Food and sound will be recurring, I am sure.)

The space carved out by the Taco Truck, sitting in the corner of a parking lot off of Bryant St., fits the spatiality produced in these walks.  The truck extends the sidewalk perpendicular to the street, expanding the realm for interaction, disregarding even the separate domains of "sidewalk" and "parking lot".  As I move through the city I too shrug off familiar boundaries.  Neighborhood lines and so-called historic districts do not exist.  Building lobbies and rooftop gardens are as fair game as parking garages and subway tunnels.  Tall fences, open water, and security guards are the only things to keep me from walking somewhere.

The Taco Truck is similarly disobedient to artificial lines, though to be sure, the truck is under a set of regulations and is permitted for certain locations only.  But like me, the truck is gone when lunch is over.  Have a listen:

 SF Lunchwalk: Taco Truck by nicksowers 

The soundscape before the truck is hemmed in by the propped-up metal flap, forming an awning over the space of ordering and eating.  Small, crappy speakers are embedded in the flap, drizzling out the fuzzy sound of a traditional Mexican orchestra.  Inside the truck, pans slide off the grill, carnitas sizzles, a cash register bangs close, and someone's order is called out: 95!  That's me. Shrimp tacos!
