an unconventional train recording


A while back I scouted out a remote train recording location along a track that I knew to be under pretty regular use by the freight lines that run through downtown.  Its amazing sonically, but not in the nicest part of town so I have to choose my times of day carefully since I don't want to be out there after dark.

The unique thing about this location is the fact that its right over the trinity river basin and has perfect access to the underside of the train bridge.  This presented a golden opportunity to both record a train by from a unique perspective (underneath) and to plant some contact mics on the rails and see what those things would hear.  I also wanted to do a very wide perspective since so many train bys that I hear and record lately are of the very closeup variety.

As I was still getting set up a train ran up over me and surprised me.  I panicked a bit, rolled on the audio, fretted about my contact mics not being set up, grabbed my handheld recorder, and looked for the video button on my phone.  The rest is in the vid below.



you'll notice that about halfway through I had to flip the video because I was holding my phone upside down, which made the train go in the wrong direction on the vid. good times.

 Here's a more detailed look at the setup:
Contact Mics

Mics under rails

Mics ORTF aimed up in the blimp



and here are the sounds from up close: The contact mics yielded surprisingly little sound and none of it really ended up being very interesting. On my next run I may try them on the wood rail ties. In all it was a pretty good shoot despite that, but I certainly feel as though I can get more and better sounds if I keep coming out.

As a side note, I will be posting the high res files of both the close and wide perspectives on two train passes to The Sound Collector's Club for download.  All you need to do is sign up and post a train recording of your own to get them.

Join in the fun!

stealth rig prototype

A few days ago I posted a few pix of the stealth rig I'm developing to the twitter and got some interested responses, so I'll spell out what I'm thinking in a little more detail here.


I'm actually surprised there's not a commercially available hyper portable rig with suspension and wind protection available out on the market.  Here are the needs I'm trying to address:
  • inconspicuousness - I'd like to be able to take this out into a crowd and not get strange looks.  I'd also like it to not look like a bomb.
  • wind protection - very important to be able to take this out into low to moderate wind conditions and get usable recordings
  • low handling noise - I'd like the rig to be well suspended enough that I can carry it while walking without audible bumps
  • all in one - I want the entire rig to be together - recorder, cables, shockmount and mics in one package.
Why not just roll that D50 out there in those situations?  In many cases I do.  The D50 meets all of the above criteria and does them beautifully.  (yes, I can totally walk around with it and not get handling noise)

But with all of that said when I can I'd like to run better mics.  The D50s mics are just fine for most things but I really do like my CM3s quite a bit more, and if I can create the option to use them in stealth situations then I would very much like to, so I've built this:



So here are the basic components:

-The cage:  In this case I'm using a wire wine holder I got at Hobby Lobby.  I stripped off some of the extraneous decorative wood and other bits, and was left with a sturdy steel cage and a chickenwire surround.

- The mounts: The shockmounts were part of the CM3 package that I bought from No Hype Audio.  They're very nice, compact, and they mount into the wooden bottom that I've attached to the bottom of the cage.

- The cables:  I was looking to make the most low-pro cables I could, so I jumped on Markertek and found this mogami w2697 lav mic cable (cheap), and a pair of Neutrick NM3FXI female XLRs that are basically half-length.  I got some heat shrink to work as protection and strain relief.  The upside to this type of cabling is that its super low pro and flexible.  The downside is that it's not nearly as rf-shielded as a thicker and less flexible cable.  I may try to build a pair of short right angle cables in the future.

- The recorders: That's a Deneke PS-2 on the right providing XLR in and phantom power (just tie wrapped on for now) and the PCM D50 on the left.

-the wind protection - still in testing.  I'm in the process of testing out various covers and layouts that would work here.  One idea I had was to take a piece of cloth and attach it to the bottom, then kind of flap it over and cover the entire device from front to back.  This leaves access along the sides (through the folds of the cloth) to the recording devices.  Another idea would be a basic pillow-case type cover that just plops over the top and is measured to the right length.  recorder access would be the issue to get addressed when fabricating that way.  I'm also testing which fabrics give me the best wind protection/transparency ratio.  I was pretty surprised to find out how much high end the rode deadcat was knocking down, so I still have much to learn there.

so that's it.  The rig works fine, it's kind of lunchboxy when I use the flannel cover, and it sounds great.

comment with any other questions you may have.

Quickie fieldrecording tip - tapslating

Over my last several larger scale audio shoots I've made and then subsequently ignored my input lists in lieu of a different method - tap slating.

Tap slating is what it sounds like.  You set all of the mics up about where you want them to go, then run cables and plug them into the recorder.  Hit record, and walk around to each mic.  Tap the mic and slate.

*tap tap* "that's the schoeps CMC6 MK4 on a shockmount aimed at the exhaust"
*tap tap* "this is a 421 passenger side axle aimed at the tire"
*tap tap* "that's an NT5 in the engine compartment aimed at the heads"
*tap tap* "and this is a CM3 next to the exhaust aiming out behind it"


etc.

With everything slated, set levels and you're off.


The beauty of this is that you don't have to stress about which mic is plugged into which channel at the time you're setting up.  Just run the all the cables at once, plug them all in and you're good.  It also helps on the flexibility/spontaneity side because you don't feel as tied to your preconceived ideas about where you're putting which mic.  Spend the moment setting up and listening as opposed to writing stuff down, then tap slate and start rolling.

In post you'll see the tap slates a mile away, and you'll appreciate the better descriptions that you'll dictate to yourself.

The Texas State Fair

Last weekend my wife and I took a trip to the Texas State Fair.

I did a little research beforehand, and after finding out that you can bring everything coolers of food to concealed handguns into the fair, I figured that a low pro recording rig wouldn't cause much of a fuss.  Sure enough, I got in without much of a fuss despite looking like I was carrying a weird plastic tube weapon.


The thing about the sound of the state fair is that there is music pumping and blaring everywhere and in almost every building, which doesn't leave much room for commercially usable recordings.  After about half a day I came back with a few things, but not really a whole lot of unique and distinct sounding things.

The midway was probably the most interesting sounding space, since there were rows of miked up carnival barkers calling races and hawking games to passersby.



Overall we had a great time despite not getting a whole ton recorded.  I also got that stylin hat.

A recording of Occupy Dallas

I'll preface this by saying that this is not a political blog, its an audio one.  This post is about the unique audio I was able to record yesterday.


Occupy dallas march

I'm fascinated with how crowds of people sound, and while I'm always recording sports crowds I find protest and riot crowds to be the most unique and intriguing.  There's an energy there that you can't fake, and I was certainly trolling around for some recordings after the Madison protests and the Vancouver riots happened - but to no avail.

Yesterday I was sitting around deciding whether to go record the Texas State Fair or to head downtown and record Occupy Dallas - a protest group that's formed locally in solidarity with Occupy Wallstreet.

After checking their blog, I found that Occupy Dallas was planning a march on Goldman Sachs and I decided that I'd opt for that because I didn't know how many big opportunities I would have to record a good protest locally and in a fairly safe manner.

After a little thought I decided against going full stealth for this one.  I figured that there would be tons of media out there, both from within the protest and externally so I'd probably be fine with a proper mic pair up in the air.  I loaded up my low profile rig that consists of a pair of Line Audio CM3s in ORTF inside of a Rode blimp recorded into a Sony PCM D50 - all packed into a messenger bag.  I went with a gray shirt and blue jeans so as to not draw too much extra attention to myself though.  No hat, no sunglasses.

The blog said that the march was scheduled for 1pm, and by the time I was packed and tested it was already 1:45ish, so instead of heading to the OD headquarters at city hall I went straight to the Goldman offices in uptown.  Sure enough, there they were with a pretty large presence and the police holding a perimeter around them.  I parked about a block up and became painfully aware of how much like a bomb my audio rig still looks.  I must change that in the future.

After a few speeches and chants the event seemed wrapped up and the crowd started its march back downtown to city hall.

I made the decision that I hadn't recorded enough material yet and there was too much gold just walking away from me, so I loaded up and started walking with the group, having no idea what the route was or how far they would be headed.  We ended up heading about 3 miles south and the march took about 30 minutes, with chants and cheers going on the whole way.  It was a very parade like vibe, both serious and light hearted.  

It was also a pure clinic on populist chants and callbacks.  One of the leaders had them all loaded up and ready to go, and the group was right on with the responses.



There were times during the march when the group was spread out enough that it had overlapping chants going on at the front vs the back of the line.  At other times the group was more bunched up and had the effect of sounding larger and more cohesive.  Occasionally passing motorists would honk their horns and get cheers from the group.

By far the coolest audio event of the day was when the crowd marched under an interstate overpass.  All of the sudden there was this incredible city reverb washing over the entire group.  Everyone perceived it affected the tempo and intensity of the chants.  I have a byte of that at the end of the soundcloud link above, and I have a little iphone video as well.  You can hear how much it dries up once the group comes out from under the bridge.



Once everyone reached the base camp at city hall downtown everyone kind of settled in and took a break.  I bought some ice cream from a palatero down there and after resting for a moment I walked back to my car along the same route as the march and listened to the recordings the whole way back.

In all I got about 45 minutes of great stuff.  very little editing needed, and a heck of a good recording day.  I'll save the state fair for Monday.  :)

A semi stealth recording with my new CM3s

A month or so ago I stumbled upon a thread in the gearslutz forum where people were hyping a new mic called the CM3 that comes out of Sweden from a company named Line Audio.

After much discussion some guys started putting up sample recordings of the mics in shootouts against the Schoeps CMC6 mk4 mics, and I was so impressed I jumped and bought a couple.

The company I purchased from is called No Hype Audio, and they're really just that.  Jean Pol was incredibly helpful and responsive, and he got me the mics with shockmounts within a week.

I ran my own shootouts vs the schoeps CMC6/MK4, NT5, and SM81s and came away incredibly impressed. I'll have a more detailed blog post with the shootout later on.

After a few weeks of owning these little things I can certainly say that I don't feel like owning two is enough of them - I want more.   I'm lobbying Roger Jönsson, the manufacturer, to put out a hypercardioid and a figure 8 model.  :)

 Right out of the box, the striking thing about these mics is just how small and light they are.  They're literally shorter in length than a standard business card, and they weigh absolutely nothing.

They're the exact diameter of an NT5, and have a fairly wide cardioid pattern.  Given the size I figured I could mount them in a kind of ORTF setup inside of my Rode blimp and take them on a couple of test runs.

Holding them in your hand, its almost hard to take them seriously, but oh man they deliver on the sonic front.

Mounting is shown here, and the mics fit in this configuration effortlessly.


With everything loaded up I packed the rig into a messenger bag and left the blimp just kind of hanging over the top.  It still kind of looks like a pipe bomb up there, but I decided to risk it and jump onto the local commuter DART train for a few rides and other things.  I used my ipod earbuds for monitoring and jumped on.

I was able to actually get on the train while rolling and ride from stop to stop with no issues whatsoever.  I had a guy ask me for some change, but no one looked twice at the giant rocket launcher I carried around with me, which was very encouraging.

After a few trips up and down I hopped out and got some ins, outs, and bys as well.

The results speak for themselves - excellent detail, great imaging and a way better than "useable" recording of the entire commuter train experience.

All in all I'm very impressed with the new mics and I'm working hard on a more stealth-like rig in the near future.

part 1 - overview
part 2 - research and setup
part 3 - hard decisions
part 4 - project launch
part 5 - the interim
part 6 - recording, editing, metadata
part 7 - final numbers and thoughts

feel free to leave any thoughts or stories about kickstarter or the trolley sounds here.

thanks!
