There are two things which are always possible to record almost everywhere, any time and all year around. That is traffic noise and all kinds of wind.
Traffic noise is easy to record, but wind noise is more difficult. Wind is like an instrument or a symphony orchestra. But what makes it even more difficult is that you can´t place the microphone everywhere you like. A „pure and clean“ wind recording may not include a mechanical wind noise from the windshield, cable or the tripod. So location of the microphone rig plays normally a big role. But when the microphone is placed close to ground or a wall it will affect the frequency spectrum, mainly of sound reflection and therefore a phase issue.
It is possible this happened to me in December when I recorded gust over night in the country side, west Iceland. But I am still not sure, because when all the straws on the ground were rubbing each other, they made a sound or a constant noise which was limited to specific frequency range.
There is no other recording I have made which sounds as differently between different headphones and speakers as this one. I have not EQ this recording much, just pulled down the subsonic at 20Hz and slightly lifted 250Hz (+/-100Hz) The microphone was about 30-50cm from the ground. It was very bumpy and because of that I think I was probably not struggling with a phase issue, only the noise from the rubbing straws.
This recording starts very calm, with an „intro“. But suddenly the wind starts to blow and and gets stronger in the third part of this beautiful winter song..
I am used to record exactly on this location almost every time I visit this place so it is interesting to listen how this place sounds six months later, in July. Listen here.
Quality open headphones are recommended while listening at low or medium level.

For me nothing is as pleasant as laying in the grass on a warm summer day in good distance from human activity, looking at the sky and listen to the wind wipe the grass until I fall a sleep.
This is something I did the 30th of July 2017 when I decided to visit places I remembered as a child, almost 50 years ago. It was at my grandparents´ farmland, Efri-Brú, which they owned most of the last century.
About 2 km northeast of the farm is a place named Hvítingshæðir. There is an old ruin of sheep shield, surrounded in grass field and remnants of old fence. This sheep shield in Hvítingshæðir was one of three or four sheep houses in distance from the main farm buildings. These sheep shields were usually built in places where it was easy to mow and keep hey for sheep during the winter months.
There is not much going on in this recording. Many decades have passed since farming was in the area and most birds are quiet this time of the day. So gust is playing the main role in the recording.
This was one the first recording I did with my parallel MKH8020/8040 AB setup in Rycote windshield. It was recorded on four channels with 50dB gain and HPF at 80Hz.
Quality open headphones are recommended while listening at low to mid level, or in speakers at low level.

Wind is very often the recordist´s enemy. Especially if the rumbling noise of „hammering membrane“ is not acceptable.
Some recordists may say this rumbling noise is just normal. Everyone will hear similar rumbling noise when they stay in wind.
For me it sounds like „clipping distortion“.
Wind protection is one of the most important thing for nature recordings, especially in the country where wind below 3m/sec. is almost unique.
I have tried several wind protections. My own, Rode Blimp and Rycote Softie and Modular series. All of them sounds similar. So it was welcomed when Rycote introduced the Cyclone windshield. Cyclone have Floating Basket Suspension, which is very nice. Until now, it has been only be used in the overpriced Cinela products.
Rode NT1a is one of the best cardioid microphones available today for nature recording. But sadly it is not build for outdoor use, so it has some poor futures like handling noise.
So when I choose it on the field, it has been important to keep it in Rycote modular windshield, place it close to the ground (sadly very often too close) and pray for completely calm weather. Then pray again for nice outcome.
I per-order a pair of Cyclone mini windshield last summer and got it in mid September. My plan was to fix them with parallel MKH20/40. But I also gave my modified NT1a a try when I saw it was almost „plug and play“ to fix it .
Without fur Cyclone was not far from to be equal to Rycote modular series with fur. But when Cyclone was dressed in fur the rumbling noise almost disappeared in wind around 5-7 m/s. That was a huge success.
Following recording is a short part of overnight recording from Stafholtstungur, in the west of Iceland. The gust goes up to ca. 7m/sec. and the recorder HPF was set at 80Hz. The rig is about 1 meter above the ground.
Some rumble noise is audible in this recording, but some of it could as well be a vibration from the tripod. Keep it in mind this is NT1a which is particularly sensitive for handling noise.
I will spend more time to test this setup but it looks like I need to order another pair for my MKH20/40 rig.
Quality open headphones are recommended while listening at low to mid level.

Last weekend in February I and my brother in law went to Skaftafell national park. Our sons were with us and we spent one night in a tent on the campsite. One of the reasons that we drove all this way from Reykjavík was to get in touch with the place where I will be recording the nature next spring and summer.
We were lucky with the weather. It was dry and the temp. about zero. But most of the time strong gust was blowing down from the glacier over the place.
This recording was made during midday on the campsite where the gust was blowing through the naked branches.

Skaftafell í febrúar 2014

Síðustu viku í febrúar fór ég með mági mínum í stutt ferðalag austur að Skaftafelli. Höfðum við syni okkar með því veðurútlit var gott og við ætluðum að tjalda. Var ferðin að hluta til farinn vegna hljóðritunarverkefnis sem ég fékk styrk til að sinna næsta vor og sumar. En styrkinn fékk ég hjá samtökunum Vinum Vatnajökuls.
Á meðan við dvöldum þar þá gekk á með hvössum vindstrengjum ofan af Skaftafellsjökli. Það var því kjörið tækifæri að hefja hljóðritunarverkefnið með því að hljóðrita vindinn sem geystist í gegn um kjarrið á svæðinu.

Last summer was mainly wet, windy and cold in Iceland. It was no exception while I was recording birds in the nature reserve Flói, south of Iceland.
I was three weeks later than usual, so it was probably too late to record a reach bird chorus.
I spend two nights in the area and tried to record surrounding ambient through soaking wet windscreens. I stayed most of the time in a bird watching shelter to keep me dry. It was different from last tree years. Surroundings looked more like a swamp than grassland.
I kept one recorder in the field in a plastic box. The second one was in the bird watching shelter.
Just before I fell a sleep on the floor I started to record. The following recording is a short part of that moment while shower passes over.
Most windows on the shelter were open so birds surround are audible. Background noise is not a traffic, it is the surf at nearby south coast, about 3 km away.

Flói 2013. 1. hluti

Síðast sumar var kalt og blautt miðað við það sem maður hefur vanist síðustu ár. Alla vega elti óheppnin mig með leiðinda veðri á röndum hvert sem ég fór með upptökutækin. Hin árlega ferð í Flóann var þar enginn undantekning. Ég mætti á svæðið þremur vikum seinna enn vanalega. Ég mátti því búast við að fjöldasöngur fugla væri farinn að dvína. Vindasamt veður gerði svo erfitt um vik, hvað þá að hljóð gæti borist langar leiðir.
Að vanda tók ég upp í tvær nætur í flóanum. Í þetta sinn flaut allt í vatni og því ekki hægt að liggja úti í grasinu eins og vanalega, heldur var leitað skjóls inni í fuglaskoðunarskýlinu.
Fyrir utan var eitt upptökutæki að taka upp á hefðbundnum stað. Annað var aðgerðarlaust inni í skýlinu. Rétt áður en ég fékk mér lúr á gólfinu ræsti ég upptökutækið. Hér kemur partur af þeirri upptöku þegar skúr gekk yfir svæðið. Gluggar voru opnir svo það heyrist í fuglum í grennd. Suðið í bakgrunni kemur frá briminu suður við Ölfusárósa.

In last week of August the first “real winter storm” arrived to Iceland, with strong cold wind and snow down to 300 m o.s. Luckily it was not as bad as weather forecast expected.
But for sure more and stronger storms will arrive in coming months. Sometimes it happens during high tide and with extremely low air pressure so the whole harbor is floating in deep seawater.
Last autumn 2012, we got at last two times a “real storm”, and both this storms arrived while I was at work. It was really dangerous to be outside so we spent most of the day inside. Regularly we heard loud “drumming sound” and got a taste of an earthquake when containers and reefers flew of the stacks to the ground.
Following recording was recorded in one of those bad weather situations 2nd of November 2012. It is mostly audible wind noises with flying garbage around when suddenly somewhere in the harbor one container take off from a stack and fells to the ground.

Fljgúandi gámar

Upptaka frá Sundahafnarsvæðinu í Reykavik frá því 2. november 2012, þegar gekk á með miklu norðan hvassviðri. Þá fór mikið af Sundahafnarsvæðinu á flot og nokkrir gámar tókust á loft með miklum látum. Í upptökunni sem hér fylgir má heyra í gám þegar hann fellur úr stæðu einhvers staðar á svæðinu.

Seltjarnarnes

Sometimes when I am going to record a specific sound I bring home something totally different.
That happened 4th of July 2012. It was a very nice weather, calm and dry, so I made a decision to cycle with my gear to the shore at Seltjarnarnes to record bird sounds and ambiance.
But shortly after I left home the wind started to blow and it got stronger with cold northern breeze . When I arrived to Seltjarnarnes the wind was too much for almost any wildlife recordings. So as usual with most cycle trips like this, I decided to go back.
But before the wind blow me back home again I found a shelter on wooden platform beside a golf clubhouse. And there was an interesting sound. Two golf course flags with poles were flapping and hammering two picnic tables. Their flaps were like an “audio indicator” for the wind waves.
Arctic Tern, Oystercatcher and other bird spices in combination with heavy sea waves at the shore made this all as a great concert.
I stayed there about one hour while I recorded and listened to the concert, watching a thick smoke coming from burning garage in Kopavogur district, seven kilometers away.
Following is twenty minutes of this session.

Fánar í vindi

Ætli það séu ekki í u.þ.b. 80% þeirra ferða sem ég fer til að hljóðrita, að ekkert kemur út úr því. Oftar en ekki er ætlunin að taka upp eitt, en ég kem heim með eitthvað annað. Þá gerist stundum það óvænta að slík hljóðrit koma skemmtilega á óvart.
Eitt af slíkum tilviljunum var hljóðritað 4. júlí 2012.
Logn og blíða var í Austurbænum svo ég ákvað að skjótast út á Seltjarnarnes til að fanga dásamlegt sumarkvöld nærri sjó með fjölskrúðugu fuglalífi. En því nær sem dró Nesið því snarpari gerðist vindurinn og þegar þangað var komið var ekkert veður til að fanga nein rólegheit.
Áður en ég lét goluna feykja mér til baka þá ákvað ég að leita skjóls undir skyggninu við Golfskálann. Þar vanaði ekki hljóðin sem umsvifalaust gripu áhuga minn. Tveir golffánar á nestisborðum hömuðust þar í takt við breytilegan vind. Þegar svo við bættust önnur hljóð frá kríu, tjaldi og öðrum fuglum sem og þungum nið haföldunnar, þá hljómaði þetta eins og skemmtilegt tónverk.
Ég kveikti á upptöku og naut tónverksins í klukkutíma á meðan ég horfði á breytilegan reyk leggja frá eldsvoða í Kópavogi.
Hér má heyra 20 mínútur af þessu hljóðriti.
