Do You Have a Rooftop?

Lately, I’ve been spending days and nights on rooftops all over NYC for a collection of surround recordings from up high.

One of my favorite locations this far is a rooftop on 20th and 2nd avenue. This location came with a lovely view of the Empire State Building, and, if it hadn’t been for the temperature, I could have stayed out there for hours. 15° Fahrenheit isn’t always the most conducive climate for sightseeing, but this night was special. The skies were clear, the Empire State Building was lit up in classic white, brakes were squealing, and the firetrucks were out. I was in heaven. Here’s a little sample.

I’ve been making these recordings in quad using Schoeps MK4’s in a double ORTF configuration. I’ve also been dragging around my Cooper CS104 as a front end for my Sound Devices 744T.[1]

I’ll come out and say it, none of this is convenient. My kit involves a bag with the Cooper and Sound Devices, a Pelican 1510, and all the other little fiddly bits go in a backpack. The looks I get when I drag this morass of stuff on a packed subway train are priceless.

This process also involves a fair amount of goodwill from my New York friends and colleagues. Thankfully, my New York friends and colleagues have been willing to indulge me.[2] I’d go as far as to say that I have been extremely lucky. Two rooftop visits included meals and another included cocktails. I don’t know if folks are taking pity on me or if I look that harried, but those rice cakes I had with that almond butter were more delicious than expected.

I am still on the hunt for more rooftops in NYC, so if you live in any of the 5 boroughs and have roof access (or know someone who does), and would like me to document the sound of your roof for posterity, drop me a line. Please know that snacks and cocktails are not required.


  1. I always say, “If you want your ambiences to sound right, don’t leave home without your Cooper CS104!”  ↩
  2. I’ve been lucky in work and in my friends. All too often my friends are willing to support my crazy recording endeavors in any way they can and, for that, I am in their debt.  ↩

When the City Sleeps

New York City is supposed to be the city that never sleeps and for the most part it is. The Big City always seems as if it is hustling and bustling – on some rare occasions, you can catch it sleeping.

I spend a fair bit of time working on the east side of Midtown and it is a commuter’s wasteland. It is a part of the city that is often dead on the weekends and jam packed during the weekdays. I did some recording over the Thanksgiving holiday, and it was a rare opportunity to get some material when midtown was quiet. Below are two perspectives – one facing 47th Street, and the other is facing 3rd Avenue between 46th and 47th.

The gaps of relative silence occur when cars on on 3rd Avenue are stopped at a red light. Occasionally a car will turn left from 46th Street, but it is rare. This kind of relative silence in the middle of a weekday that is definitely abnormal.

Another kind of relative silence that is worth recording is either in the middle of or after a snowstorm. I spent a little time recording in the same locations right after our recent snowstorm. The roads were relatively quiet but the slush was a thing of beauty:

I love the plow that rolls up 3rd Avenue pushing the slush all over the sidewalk. One passerby got nailed. You’ve got to look out for the department of sanitation!!!

Back in September I wrote about recording typewriters, and the generosity of Tom Furrier of Cambridge Typewriter. It only took me six months to finish the material, but there is now a completed SFX Library:

I recorded seven machines from 4 perspectives:

  1. Close
  2. Distant
  3. Under Keyboard, Close
  4. Under Type Bars, Close

With a ton of actions per machine:[1]

  • single keys
  • punctuation
  • jammed keys
  • spacebar
  • spacebar, repeated
  • tabulator
  • fast tabulator
  • shift
  • shift + key
  • backspace
  • backspace
  • carriage return
  • typing, slow
  • typing, medium
  • typing, fast

One of my favorite machines from the collection is the Remington Standard. If you are thinking that the name Remington means “heft” then you would be correct.

The strength of this collection is not just the diversity of the material, but the variety of mechanical sounds that can be generated with simple pitch shifting. Check out the recordings at 1/2 speed.

I am very happy to have this collection in the world, but I can’t say that I was loving life cutting typewriters all of the time. There was a long period where I thought one more key depression my crush my soul. There are over 400 files, with multiple takes in each file, so you can imagine how oppressive the clicking and clacking of typewriters can be. All of the complaining aside, I’m very proud of the diversity of sound in this collection and I owe a big thanks to Tom Furrier at Cambridge Typewriter[2] for access to his collection and his unwavering, magical typing hands. I also owe a big thank you to Mitch Hanley and Kelly Pieklo for their ears and feedback.

I’m looking forward to finding something rather quiet to edit, but sadly it is isn’t on the horizon.[3]

Grand Central Stealth

We all encounter situations where walking around with a large Rycote and a big Portabrace bag might not be ideal. There are times where ambiences need to be recorded without our subjects reacting to the fact they are being recorded. This is where having a good discrete recording setup is always handy.

The Tapers Forum has a plethora of examples that are worth exploring. Most of the content on that site is geared towards concert tapers, and you’ll see a ton of crazy setups for recording really bad PA systems.[1] That said, it is worth a visit to generate some ideas.

Every few months I make little tweaks to my stealth rig. Currently my rig consists of a pair of DPA 4060s that are head-mounted, a Sound Devices MP–2 pre-amp, a Sony PCM-M10, and a custom bag with cable routing.

It all works quite well and I recently took the rig out to test my recent tweaks. After running some errands, I crossed town and did some recording in Grand Central.

One of the spots I really dug was a small corridor between the main concourse and Vanderbilt Hall.

To the east of the corridor is a ramp that heads down to Metro North trains.

There is significantly less foot traffic in the corridor and there is a beautiful diffuseness to the sound in that location.

I was able to stay in that position for a while, but when you stand in one spot not moving your head, you start to look a little weird. If you move your head, you mess with your stereo image![2]

Apparently, I was not attracting too much attention because this happened:

Who says New Yorkers aren’t nice people! You know you have a decent stealth rig when tourists stop so you can take their picture.


  1. I don’t know why a pair of Schoeps CCMs mounted in your hat is really necessary when you are essentially recording a junky PA and the guy next to you screaming “Free Bird” every 5 minutes, but to each his own.  ↩
  2. Don’t move your head!  ↩

How I Learned to Stop Worrying and Love M/S

This post comes from guest contributor, Charles Maynes. Charles is a talented Sound Designer, Editor, Recordist and all around decent fella.

I’ve also added a few footnotes that might be helpful -Michael


As a child of the Cold War, I always loved the film Dr Strangelove, and now can mark off my bucket list my misuse of one of its most humorous tag-lines: “so with that said, in we go …”

I am going to need to give a little disclaimer, this little piece is an opinion piece, with little science attached to it. There is plenty of great writing out there as to the principles of Mid Side microphone techniques[1], and it isn’t my intention to add to the serious academic tone of those. There is no “answer” at the end of this. It is just a batch of information that will empower you to decide whether this is a good fit for the way you might want to do things.

As a sound designers, sound editors and sound effects recordists, we have all sorts of techniques and practices at our disposal. We use high sample rates and different bit depths. We also work in mono, stereo and multichannel formats. Usually, we are constrained by one condition or another, and many times we are simply constrained by time itself. In the field and in the studio, working with stereo signals we usually are most comfortable with Left, and Right channel audio. The reasons for this are pretty simple: most people with any sort of audio skills are usually very comfortable working in that format. And to be stating the obvious, our reproduction systems pretty much demand that. When we look at more esoteric formats like M/S, double M/S, B-Format and discreet surround, as the Holophone class of microphones provide, we are quickly swimming in a sea of options which may or may not make our creative work more efficient. Since I am discussing the basic Mid Side technique, I will hit the pros and cons as bullet points, which I will address in greater detail:

Mid Side “Pros”

  1. A real mono center channel- this is pretty important, and quite cool.
  2. Stereo width that is adjustable after the fact.
  3. The same channel requirements as other stereo mic’ing setups
  4. single point microphone placement- which is more convenient, and can be hand held with relative ease and comfort.
  5. The ability to use different pattern mics for special purposes and still have a stereo compatible result.
  6. The ability to use processing on the Mid or side mics independently.

Mid Side “Cons”

  1. PITA file management
  2. PITA auditioning in library programs
  3. PITA use in mixing
  4. PITA use by team members not versed in M/S work flows.

I am sure there may be other pro’s and con’s, but those are my pet favorites. Now to dig into the list!

On the “Pro” side.

  1. A real mono center channel- this is pretty important, and quite cool. There is NOTHING better than a true mono recording of an effect if you need it. Mixing stereo down to mono is sometimes workable, but in most cases we just chuck one side and move along. Is that good enough? Well in most cases it may be, but its not as good as a nice mono recording in the first place. The one thing to recognize is that all the other stereo microphone techniques are really based on the idea of recording the space around the subject, so all the mics are off axis to one degree or another- in M/S, that is not the case. Our Mid mc is pointed directly at the subject.
  2. Stereo width that is adjustable after the fact. That pretty much states fact. We can add or subtract the side channel at will to determine the degree of space we like. The added benefit for this is that our side mic is an off-axis angle which might actually be useful on its own. One thing that is possible via plugins is that we “could” convert X/Y or ORTF recordings to M/S via plugins, but we will not end up with the same flexibility due to the fact that we must use matched microphones for those other techniques (or at least “should” for somewhat convincing stereo).
  3. The same channel requirements as other stereo mic’ing setups. M/S is a 2 channel format, and where things get interesting is if we add a third channel with a rear firing mic in order to achieve double M/S for a 4 channel result, and since we have a discreet mid mic, that could also become the center channel for a 5 channel recording. Pretty cool stuff!
  4. single point microphone placement- which is more convenient, and can be hand held with relative ease and comfort. Again, this is pretty obvious, we can do an MS mic package in a single blimp with not too much trouble- something that is more of a hassle with ORTF or spaced omni setups. It also means it requires only one mic stand to carry for the stereo setup….
  5. The ability to use different pattern mics for special purposes and still have a stereo compatible result. This is where things get interesting a cool. Since you have two mics, you can use whatever you like for your M mic[2] (pretty much) you could use everything from a cardiod to a long shotgun and still have a variable width stereo signal- other things though that are less standard is say, using a core M/S package with a hyper cardiod and figure of 8, and running a second forward firing mic that is a short shotgun, or even a dynamic. There’s lots of cool potential there.
  6. The ability to use processing on the Mid or side mics independently. This is one of the most compelling things the M/S format offers. You can change the stereo image by eq-ing the mid and side mics independently. Once you try this, I am sure a good deal of people will be very much into the results. This provides tonal shaping that is not easily available in other stereo sources.

Now to the negatives….

  1. PITA file management M/S files live in their own universe as far as editing programs go- if we use M/S clips in our editorial work, we need to have the ability yo use plugin matrix solutions to yield our expected stereo output. This requires any M/S tracks to have those plugins as a part of their channel strips, and though simple, they do require system resources. Some plugins are very simple like Wave’s MS Matrix which basically has a set balance level which is not adjustable from inside the plugin, so in order to use that effectively, one would need to run a double mono trim plugin in front of it to be able to control the mid to side balance. It is not a deal breaker, but a PITA. Other plugins like HOFA’s level control plugin (which is free) have better control, but still need to automate if the channel is using both M/S and standard stereo clips in it.
  2. PITA auditioning in library programs The problem is basically the same as above. Our librarian tools need to be able to decode M/S and hopefully do it without too much effort[3].
  3. PITA use in mixing The same core problem as in #1. M/S is not dub stage friendly, and requires forethought by the mixer to effectively use it. I cannot think of many mixers who look forward to getting M/S tracks instead of regular stereo ones.
  4. PITA use by team members not versed in M/S work flows. The issue here is that if M/S files are a part of an editorial workflow, it will take editors extra time and effort to deal with them. They largely don’t want to spend this time since it takes away from editorial, and they probably aren’t going to be enthused about it. This is mainly due to the anxiety of whether the mixer wants the tracks instead of straight left/right stereo. Making lives hard for mixers usually isn’t a great career move either.

Conclusions

I have to say that I have moved from being anti-M/S (due to the reasons above) since getting my Oktava setup up and running. I have worked with a few M/S rigs and found them not particularly compelling, but the Oktavas are making me very happy about what can be done with the technique.

I love mics and I love stereo. I regularly use lots of neat and lovely stereo mics. The Sanken CSS5 is probably my “desert Island” mic. The SASS gives a type of binaural effect which can be very nice, and lastly my old, but still appreciated Shure VP–88, which sort of steered me away from M/S in the first place.

Now you are probably thinking that with the most popular M/S setups being either the Sennheiser MKH range, or the Schoeps which are certainly an industry standard, how did I end up with the Oktava rig? Well, I have to say it was an odd twist of fate for the most part. I read Tim Nielsen’s great articles on Designing Sound and focused my attention back on the M/S world, and then some collaborators I know, Zach Seivers and Justin Davies quizzed me on the notion of M/S recording. They were both looking to get Schoeps rigs for a film they were starting on and I spent some time going over the pros and cons, much of which I have already mentioned here, and let them sort the idea out for themselves. As it turned out, they both thought that the added effort was worth it, which pushed me towards putting together another MS rig myself. The Shure VP88, is an M/S mic with a built in decoder to provide a stereo or discrete output, but for whatever reason, I really never got great stuff from it (with the exception of discovering it to be an awesome mic for drum overhead). I thought I needed to rethink things, and look into options that worked with mics I already had.

My favorite small diaphragm condensers I had were the RODE NT–6’s and the Oktava MK 012’s. Each performed well, but largely were utility mics for me so as I continued considering different options, I came across an announcement from Oktava that they were doing a figure of 8 adaptor for the MK012’s. I had 3 of them already, and a good collection of capsules I thought this would be a not too expensive way to go. After getting it finally from the distributor, and rigging it up sort of awkwardly in a RODE blimp I noticed a lot of things which I didn’t really like. The mics were awkward to get a stable mount for using bongo ties and cut pieces of foam. This was remedied cheaply by the Rycote stack clips, which secured the two mics perfectly. Now the second issue seemed a little more difficult to deal with, and that was running two mic cables into the blimp and not having an ocean of bumps and other distortions if I dared move the blimp. Obviously, this was unacceptable.

I remembered another friend, Tom Hambleton mentioned the Rycote Connbox. I looked it up, and was disappointed that it seemed to be a simple device with a pretty big price tag for what it seemed to be. The one feature it had that I DID love was that it allowed  me to use 5 conductor mic cables as I did with the Sanken and Shure mics. I had recording gig to cover it and I finally popped for it. The results with the Connbox were really unbelievably good. All the cable noise was pretty much gone, and it was very clean and could be easily moved. In then end it is an amazing value, which I have no reservations saying is an awesome tool.

One thing that is very important to your sanity is carefully aligning the Mid and Side mics in your shock mount. I started with my Mid mic a little bit forward of the side capsules and had difficult in mastering figuring out the right amount of delay that was need to produce a correct stereo image after the fact, but it was certainly a good learning experience.

So with that, here are some sound example of the mics for you to peruse, and hopefully you can make a good decision if M/S is right for you.

Minneapolis Demolition

Last week I posted a bit of road construction going on in Manhattan and one of my soundie pals in Minneapolis, Kelly Pieklo got in touch with some demolition recordings he had done the same week. I guess soundies and road crews think alike. Here’s a guest post from Mr. Pieklo:

The neighborhood around our facility has seen a pretty big uptick in construction over the last 18 months. This has provided many opportunities to capture not only the general sounds and cacophony of construction worksites, but also engines of earth-moving machines and the sounds made when using these vehicles.

Recently, however, the building immediately next to ours, Merit Printing – a one-story brick facility – was sold, and was to be demolished for new construction.The demolition took a total of about 4 days, and I managed to get outside for about 3 of those days to record.

It was nice to hear less of the machines, which I was concerned would overpower the recordings, and more of the sounds of the dropping, knocking over, and scooping of various building materials – wood, brick, concrete, glass block, and metal. I think I appreciated most the sound of a wall of bricks tumbling over. Additionally, unlike the stereotypical wrecking ball demolition I was (sorta) hoping for, the bringing down of the building had to be carried out very carefully, as our facility and Merit were very, very close. Very few large crashes, and many more smaller, controlled crashes.

The wood sounds you hear are the sounds of the crane digger operator carefully pulling the wood framing away from the concrete walls by using the digger’s bucket. I was amazed at the precision of the operator in these situations – it took a very gentle touch to pull these small pieces of wood without simply knocking the entire wall over. Most of the glass breaks are glass blocks, which sound far different than panes of glass – almost like clay bricks with some higher tone resonances.
