Recording wind

After releasing the Norsonant library “Windy forest” I saw a lot of comments online about wind being challenging and difficult to record. I don’t disagree, but I’ve picked up a few tricks over the years that help. Most of them are pretty basic, but if you know about them all it adds up and makes things easier.

Let’s start with a list of tips and then we’ll get into details.

  • Correct microphone placement in the zeppelin
  • Use extra layers of wind protection
  • Use natural cover
  • Aim the microphones at something
  • Keep the microphone stand from tipping over
  • Record long takes

Correct microphone placement in the zeppelin

The zeppelin works by creating a volume of still air around the microphone. For this to work properly there needs to be a little bit of distance between the microphone diaphragm and the zeppelin. I’ve seen people push the microphone all the way to the front of the zeppelin to get as close as possible to the sound source. This means that there is very little room front of the microphone and reduces the effect of the zeppelin. I generally leave as much room in front of the microphone as between the microphone and the sides of the zeppelin.

This tip only applies to microphones with the diaphragm near the front, like a Sennheiser MKH 50 or a Rode NT5. If you’re using a shotgun microphone, the design of the microphone itself will keep the diaphragm from getting close to the front end of the zeppelin.

Use extra layers of wind protection

You’re used to using a furry wind jammer to protect the microphone from the wind, but sometimes that’s not enough. I’ve tested a different ways of adding wind protection.

The most professional solution is the Rycote Hi wind cover. The Hi wind cover is made of a fleece material that slides over the zeppelin. The wind jammer goes over the Hi wind cover. The fleece material gives you an extra layer of wind protection and this has been a life saver for me many times.

The low budget solution is using a second furry wind jammer as an extra layer. Just slide an extra wind jammer over the one you’re already using and that will give the microphone some extra protection. This works, but not quite as well as the Hi wind cover.

Use natural cover

Unless you’re recording in a wide open field or something like that, you can probably find some natural cover that will help protect you and the microphone from the wind. If you’re in the city you can try to get behind a house or wall. In the forest you can find lower ground, a small valley or hide behind a big rock.

If all else fails you can position yourself between the microphone and the direction the wind comes from and use your body as wind protection. This naturally won’t work if you’re wearing loose clothing or anything that will flap around in the wind.

Aim the microphones at something

The air that the wind moves is not very interesting in itself. Don’t just aim the microphones at the horizon. Try to aim them at something that the wind interacts with. Aim them at a tree, straight down at the grass, at the rusty gate or at the hole in the wall that makes the wind sing. This is the same principle as when recording rain. Thousands of rain drops is just white noise. You are looking for the details that make it sound interesting.

Here’s an example from the Windy forest library. I’ve pointed the microphones straight down to capture the sound of grass moving in the wind.

Keep the microphone stand from tipping over

This should be pretty obvious, but I know I’ve let my microphone stand tip over many times. Shame on me. Zeppelins break and so do microphones, so be careful.

  • Keep your foot or hand on the stand
  • Place something heavy on the base of the stand
  • Keep the stand low to decrease the chance of it tipping over

Record long takes

Even if you are very careful, you’ll probably get some wind distortion on your recordings. Long takes make the editing process a lot easier. Instead of having to low cut away wind distortion you can just cut away the entire section and still have plenty left to work with.

Sometimes you want both clean wind sounds and dirty, distorted wind sounds. Long takes will give you more to choose from.

That’s all the tips I have for now. If you want more you should go read Gordon Hempton’s blog post about wind recording.

Wind turbines

My feet were soaking wet. A strong wind blew across the flat terrain around me and the sun was still slowly working its way up from behind the mountains. This was going to be a cold day at work.


In this blog post I’ll tell you about the pre production and recording of the sound effect library “Wind turbine” for Norsonant as well as the equipment I used.



In December 2015 I decided to try to record some wind turbines. After doing a bit of research online I found two nearby sites with wind turbines. One is a large area with more than ten turbines near a road, so it’s easily accessible. The other is a smaller area with only two turbines, further away from civilization. After carefully checking maps and satellite images, I hiked out to the smallest site to do some location scouting.


If possible, I like to go out on location before the day I actually plan to record. It just makes everything easier. Using maps and satellite images can tell you a lot, but nothing beats going there in person. When location scouting I can use my ears to listen for potential problems and decide how to best avoid them. Sometimes I need to bring extra gear to help me get rid of the problems. Sometimes I need to find a different recording location. Without taking the time to scout the location I wouldn’t know. In this particular case I wasn’t which route to take to get to the wind turbines. I’d rather get lost and walk for hours without carrying lots of microphones, stands and other gear.





At the site I found a few challenges I had to overcome, but all in all it was a good location. The biggest problem was that there were two wind turbines pretty close together. I found a good spot for the microphone that would let me isolate one of the turbines enough to make it work. There was a bit of noise from distant traffic, but recording early in the morning should solve that. I also found out that the road nearby was open, not closed by a barrier like the map said. This meant that I could drive to the other side of the area, park my car a lot closer than I thought and save myself from a lot of unnecessary walking. The location scouting trip was already worth it.


I prepared my recording gear the evening before the session. Since I was going to walk to the recording location I wanted to travel light. I’ve fallen in love with the Manfrotto Nano stands as they are super light and can be folded to fit in a backpack. This session would be the first test for my shortened Rode blimps, or “mini-me” blimps, as Watson Wu named his in the blog post I stole the idea from. In the blimp I placed my recently purchased Line Audio CM3 microphone. The recorder was, as always, my Sound Devices 744T. This setup is very small and light, so I was not worried about the weight of the backpack for the hike the next day.





Recording day. I got up early so I could get to the location before traffic started picking up. The wind shook the car, so I started looking forward to listening to fast spinning rotor blades. I drove the car as far as possible and walked from there. It was a windy, but dry day, so I had chosen to wear sneakers. Oh boy, what a mistake that was. Since I was approaching from a different direction, I had to cross a mire. Long story short, that wasn’t happening without getting my feet wet, but I was set on getting the recording done.


When I got to the turbine I had decided to record I set up the gear as quickly as I could. They tend to place wind turbines in areas with plenty of wind, so my wet feet were starting to get cold. I recorded from a few different positions to capture different distances. I also wanted to try to get different intensities, so I recorded long takes to give the wind a chance to change. The final position was right next to the turbine, about a meter away. I extended the microphone stand all the way to get as close as possible to a vent from that let sound pass through from the generator room. The wind was so strong that the wind tipped over the stand several times. The blimp hit the concrete so the microphone loosened from the suspension and got shook around pretty good. Both the microphone and the blimp survived the fall, so all was good.





I walked away with pretty cold feet, but some good recordings after a two hour session. On the trip back, I took a detour to scout the other wind turbine location. Unfortunately this area was too close to main roads and the airport, so I quickly decided that there was no point in recording there.


Lessons learned:

  • Location scouting can save you hours of walking.
  • Keep your hands on the microphone stand when recording in strong winds. It only takes a second and a strong gust to tip it over.
  • The Rode wind jammer works surprisingly well and I’m very happy with it. I still wish I had brought a Rycote Hi wind cover to protect the microphone from the strongest gusts.
  • The shortened Rode blimp, or mini-me, is awesome and pretty easy to make.
  • Don’t be stupid. Wear proper shoes.

Field recording

Liberation day cannon salute

Yesterday I found out that a gig that was booked for this morning wasn’t going to happen. Trying to find something constructive to spend my free time on, I remembered that the armed forces usually fire off a canon salute during liberation day. I checked the newspaper and the web and found this to be true also this year. I’ve never watched the canon salute at the fortress before, so I left the studio to go location scouting.

At Akershus fortress I first went by the visitor center to check when the salute was happening, where it was happening and if I would need and could get permission to record. Some of the questions a field recordist may ask can sound like questions from a weirdo to other people. Especially my “how close can I get to the guns when they are firing” question raised a few eyebrows. Unfortunately I couldn’t get a good answer about permission to record and it was too late to get a hold of whoever was in charge of making those decisions. I just had to go there the morning after and hope for the best. I was unsure if I should bring a full recording kit or the stealth rig, but decided to go for a full kit. I walked over to the cannon area, had a quick look around to find a good position and left for home.


Apart from the possibility of being tackled by the military police, I had a few other worries. When I got home and started doing more research online it became clear that the scheduled time for the salute was either 9 am or at noon. I found contradicting information on official websites, so I just had to get there early to be sure not to miss it. I also found out that the cannon area I had scouted was the wrong one.. The correct place had a bigger surrounding area allowing for more flexibility for microphone placement, but it was also big enough to let a large crowd gather. Cheers and applause from an audience is not on my wishing list, but what can you do when it is a public event. I decided to look at this as valuable practice for when I get to do a controlled cannon recording sometime in the future. I’ve never recorded cannons before, so even if the sounds were ruined by the crowd at least I’d get some experience for next time.

Because some of my gear is currently out on a shoot, I just packed what I had on hand. The rig I brought consisted of my Sound Devices 302 mixer + 744T recorder, a Rode NT4 stereo mic and a Shure SM58 dynamic mic. I also brought my Zoom H2 as a backup.

I arrived at Akershus fortress about 25 minutes before 9. All gates but the main one are closed that early, so I had to take a detour to get to the cannon area. When I got there I ran into a couple of MPs who were guarding the site. They didn’t see any harm in letting me record the sound of the cannons, so they let me pick a position pretty close to the action. The clock was getting close to 9, so I set up quickly to make sure I was ready.

I placed the Shure SM58 about 5 meters from the closest cannon, 90 degrees to the right of the barrel. The Rode NT4 was placed about 10 meters from the closest cannon, a bit further behind the barrel. I found a place behind me for the Zoom H2. About 15 meters from the closest cannon, facing away to capture the slapback from the city buildings.

No crowd in sight, just a few photographers and reporters on the far side of the cannons. Everything looking good. I see the artillery soldiers approaching and I hit record. Immediately 744 display flashes “slow” next to the CF indicator. My CF card decided to crap out on me. I had no time to change cards and I was recording to both CF and HDD, so I crossed my fingers and let the recorder run.

Ready! Fire! I feel the shock wave and see the limiters on my equipment engage before everything is covered in smoke. After 21 shots, it’s over.


I pack up my gear and rush back to the studio to listen properly. My CF card is messed up and has only recorded a few seconds of audio. Very strange since this is a card I’ve used many times. Hopefully it’s a problem that a quick reformatting will fix. i will be testing that later. The files on the HDD are fine, so no worries. The recording sounds pretty good. The SM58 did not deliver what I had expected from a mic that close to the cannons. The Zoom H2 really delivered and sounded a lot better than I had expected. I can definitely get something good sounding out of this raw material. I’ve uploaded some samples and a few quick mixes to give you an idea of what can be done with a pretty basic setup like this. The playlist includes the raw recordings of all microphones with no processing. I’ve only normalized the tracks. I’ve also included some quick mixes with different variations of limiter use on the tracks. Enjoy!

Have you ever done foley on location? I’m not talking about recording sound effects on location/field recording, but actually recording foley to picture on location. I feel that location foley can add something special to a project. I don’t do it for every project, but I like to do it from time to time.

I wrote about my very first location foley session in an old blog post. On that project we brought a laptop, an Mbox2 and a microphone and recorded straight to Pro Tools. The location was indoors and easily accessible, so recording to a laptop was easy. We had a power outlet nearby and we even had a table to set up the gear on. Not all locations are like this.

Currently I’m working on a short film with a lot of mountain hiking scenes. We decided to do some location foley for these scenes. I was not going to carry my laptop and audio interface for miles and miles and set it up in the forest, so I went for a lighter setup.

My weapons of choice are the Sound Devices 744T recorder with a Sennheiser MKH-60 to match the production sound.


Early morning. Getting ready to record after a long walk.

On a project I worked on years back, we used an ipod touch to view the video while recording. This is a simple solution that works, to a certain degree, but you’ll spend a lot of time when you get back in the studio. Syncing the recorded sounds was a pain. I wanted to make this easier for myself this time.

Location foley video

My solution was to send the production sound from the video to a second track on my recorder. This way I had a guide for syncing when I got back to the studio. I used a wireless transmitter, but a wired connection will also work, of course. For this session I needed the freedom to move around while the recorder remained stationary, so wireless was my only option. Every time I hit record, I slated my actions as well as the time code shown on the screen. When I drop the recorded file into my session later, I can see where the production sound starts and place this at the slated time code location.

Below you see the waveform from one of the recorded files. Track one starts with my vocal slate. A few seconds later you can see the waveform of the production sound on track two.

I hope this will help some of you and save you a little time syncing your recordings. Check out Walter Murch’s metronome trick from The Godfather 2. It’s awesome.
