Here is a recording that came as a surprise after I put it in Spectrogram, because I was sure that I had not recorded anything special.
Earlier the evening before the recording started, a lot of wind had been forecast for later that night. So I was not spreading recording equipment around me as I would have liked in this wonderful and secret place in the highlands.
However, I decided to use Lewitt LCT540s in an IRT cross in a sheltered place from the coming storm. Two of the four microphones were pointed as much as possible into the ground, while the other two were allowed to point out into an open area. The recording seemed to only sound interesting in the wind that was present when I started the recording. The entire time I had been at this place in the highlands, I had not heard birds or any other life. Only in the wind and the flow of water in the nearby water sources.
But later that night while I was sleeping, a completely calm weather came that seemed to awaken a lot of birdlife. Birds that I had neither seen nor heard earlier the days before.
However, I never noticed this peaceful weather that night or this bird song. I just went to sleep in the breeze and woke up in a storm. It was therefore quite amusing to discover that I had managed to record the birdsong even though the microphones were placed in the wrong place for such a thing. It was first and foremost the microphones facing the ground that captured the most bird song. Those facing out into the open mainly recorded the behavior of Red necked phalarope which were at a considerable distance and goose in far distance.
To be honest, considering the placement of the microphones, this is a surprisingly good recording. This can probably be attributed to these excellent Lewitt microphones, also because they were not very visible to the birds that are best heard because they do not emit warning sounds. But if I had worn the microphones in something other than fur and been positioned closer to where the birds were, I would have achieved incredibly clear recordings in the most subtle way. In addition, very distant sounds would have become more clear and focused. But it is always difficult to be prepared for such weather conditions that it is possible to be without fur in Iceland when such times are perhaps 6-12 hours a month.
You can hear in the entire recording running water, also a kind of rumbling from running water that I assume could be a stream of spring water below the ground. But in this area there are huge water sources that could probably serve a city of millions with fresh water. The sound was recorded at +50dB gain and increased by +20dB in post up to -10dB. No RX noise reduction, mainly because I have never been satisfied with the result when I have used the LCT540. But EQ was used. Sharply pulled down below 50hz and above 10Khz, mainly to bring down unnecessary rumble and white noise from the equipment.
Quality open headphones are recommended while listening at low to mid volume.

I must admit that I have posted a recording with this particular mouse before, but it does not play a major role in this recording.
It is the silence, the „calm“ weather and light gusts that can be heard in the recording that I have now been waiting for for almost two weeks, i.e. the end of May – June.
The summer is not going to start well for sound recordings. Winds are well over 4 m/sec and very cold, sometimes up to -3 °C. Normal wind has been all over the country around 4-9 m/sec up to 20-32 m/sec in some places and days.
The situation has therefore been easily called a traditional „winter storm“, then and when snowfall is added.
In such weather, bird song falls silent and young birds die in nests, although some birds are breeding again.
This weather has also meant that it is not possible to install VLF antennas. But major solar storms have raged in the solar system in recent months. But VLF recordings need same weather situation as microphone recordings. Wind should preferably not exceed 2-3 m/sec if anything is to be interesting in the content of the recordings.
But then we turn to the accompanying recording, it was recorded early in the morning on November 26, 2023 under a full moon in Stafholtstungur at -1°C and 2-3m/sec which rustles gentle straw and leaves.
Because of an earlier experience. This time I thought that I had given the mouse a butter cake, that I spread around the microphones.. It is therefore quite remarkable that the mouse tried to chew on the cables that night. It starts chewing on the microphone cables with great noise (around 20 minutes). Almost throughout the recording, various sounds can be heard that can probably be traced to the mouse, especially in the last three minutes.
As it was getting close to 6am, you could hear some traffic in the distance
The SD788 was recorded with a gain of +48dB with no LPF, which was probably not wise. But if you can get away with it during recording, it’s often more fun to manipulate it afterwards. It was cut below 50Hz and above 10Khz
The gain was increased by another +14 dB to normalize to peak level in post-processing.
Quality open headphones are recommended while listening at low to mid level, or in speakers at medium level.

I made the big mistake of formatting an HD disk with photos I took throughout 2023 and into the winter of 2024, but in my absolute stupidity I didn’t have a backup. So I always run into problems if I’m going to post audio from this time period here on this blog.
But I also take photos on my SLR camera which has a fairly large card so I have consciously allowed photos to be on the card precisely to save such accidents and losing photos.
I don’t actually have a lot of good audio recordings from this summer. Both because the weather was boring most of the summer and I had the flu most of the summer vacation.
But there are a few recordings that I think are interesting from this summer. Especially the ones I took in Steingrímsfjörður and around Drangsnes in western Iceland.
I had a few pictures on my SLR SD card that saved me from being able to put these recordings on the web.
This is part 2. But part 1 was recorded at midnight, before the sunlight hit the recording location. Here in part 2 the sun has risen. Just a minute before the recording started I had to move the microphones to a slightly more sheltered spot, because over the night the wind started to increase which unfortunately can still be heard in the recording.
The recording is „unprocessed“. Recorded at +50dB gain, normalized up to -7dB by adding +20dB in post, fade in and out and then converted to mp3.
The recording starts exactly at 4:00 in the morning on June 22, 2023 and ends just over half an hour later. After a high tide earlier in the night, the tide was already starting to recede. The seaweed on the shore was still wet, which makes a soft clicking and dripping sound, which can be heard differently well with different headphones. The birds are slightly quieter than earlier this night, but the soundscape is still magnificent.
There was several gull species, at last great black backed gull. arctic tern, common eider, whimbrel, European golden plover, red throated loon, common loon, arctic puffin and eurasian oystercatcher.
There you can hear me getting in and out of the car to take pictures. Including the accompanying picture. At least one truck can be heard from across the fjord. It can also be heard in small fishing boats at the beginning and end of the recording.
It is clearly a new day rising.

I think I have annual recordings from the same place in the nature reserve in Flói in southwest Iceland almost since 2009. The reason is simple. It’s always interesting to follow the local acoustics from year to year. So I don’t have to spend a lot of time finding a location for the microphone. They stand in the same place unless something else disturbs it, e.g. high ground water level or something else that hasn’t yet happened to me. I go to the place hoping that there is no one in „my place“ in the parking lot where I can pull out my 75 meter 4ch long cable to the place where I have always recorded. I find a good ground for the microphones, get in the car, start recording and go to sleep.
I usually wake up when someone comes driving into the parking lot about 4-6 hours later.
I usually never listen to what I recorded, except when I need to look for something interesting to post on this audio blog like now.
It is well worth having a recording from Flói this month when 15 years have passed since this audio blog went online. Flói has followed this blog ever since I got my first HD recorder. It was then that the batteries suddenly lasted longer than 30 minutes, but it opened up a whole new world for me to record in nature.
Here is an audio recording from June 13, 2023. The area was extremely wet after heavy rains. I positioned the microphones to be in close proximity to the Read necked phalarope. But maybe there wasn’t as much activity as I wanted. But instead you can hear various sounds that I am not quite sure where they are coming from. There are weak „clicks“ that can be heard e.g. for 1:30 min in this recording as well during the 30 minutes that the recording lasts.
As usual, there are many species of birds in Flói. Red-throated Loon. Red-necked Phalarope, Common Snipe, Golden Plover, Whimbrel, Common Eider and certainly other duck species as well. Common Redshank, White Wagtail, Winter Wren, Northern Wheatear, Common Redpoll, Snow Bunting, Swan and maybe other bird species that I cannot name.
Background noise is some traffic and surf from the south coast and air traffic.
You can hear it occasionally in the wind because I covered the wind shield with buff but not fur. Instead, you can hear much better in subtlety details.
This is an extremely low-key recording, except where you hear the Red-throated Loon. The recording was recorded with 50db gain (40Hz HPF), then the gain was further increased by +10dB in post-processing.
Quality open headphones are recommended while listening at low to mid volume.

Last summer 2023 I went to a place I haven’t recorded much. Was it at Strandir in northwest Iceland. A friend invited me to stay in an apartment for a few days in Drangsnes, so I tried to use the time as well as I could for field recordings in the area.
It actually didn’t go very well. I had come down with a bad flu the same week as summer vacation started so I had little to no energy for many weeks. I was also facing another problem. The whole time I was in the area there was a strong wind except for maybe 1-2 hours during some nights. It was also rather cold, so nature was rather silent. Much of the material I caught these days was therefore not particularly interesting.
However, I had the opportunity one calm night to record a nice peace at the coastline. Part of it is here below. It’s very likely that I will put more of this recording on the web later, because the soundscape changed a bit during the 3-4 hours I was recording.
It is the summer solstice so it is therefore bright all day long. The recording starts at 23:45 and ends at 00:20 o´clock.
This is a typical soundscape in fjords in northern Iceland and in fact everywhere around the arctic circles.
This is a high gain recording.  Recorded at +50 db. Then add about 20dB up to -7dB peak RMS. No noise reduction in post. Just fade in and out.
Many bird species are in this recording. There was several gull species, at last great black backed gull. Arctic tern, common eider, whimbrel, European golden plover, red throated loon, Common loon, arctic puffin and Eurasian oystercatcher. Sheep were not far away and seals were lying on rocks near the beach.

Recording fireworks is probably like photographing a sunset for a photographer. Nothing special but there is always some duty that calls for it to be done.
It is not the loud sound that fascinates, but the interaction of the sound with the environment. Reflection of a sound wave. e.g. the echoes from houses, mountains or trees that make it interesting to record fireworks. The problem, however, is that I am often confined to staying at home with my family on this day. I am therefore not in different places from year to year, and therefore I have to say that I have not made a good or interesting recording of fireworks, apart from maybe one recording in Tenerife. I’m also always experimenting with microphone setups, which usually don’t work out well when there’s a lot of other things going on.
It is with mixed feelings that I put a fireworks recording on the web this time. Have done it before and therefore not urgent to do it again because it always sounds as a loud noise which is not healthy for the ears or speakers.
But this new year is marked by terrible wars, which unfortunately all have their origins to the western hegemony and imperialism, as usual. Most recently with the targeted genocide in Palestine which as of this writing can easily escalate into an even bigger war, more or less all over the middle east.
The NATO proxy war in Ukraine is still going on after almost ten years conflict. It has destroyed Ukraine and seems to be also destroying Europe in coming years, if not in decades because of politicians stupidity. This time, the West, led by the United States, EU & GB has lost both credibility and the trust of most nations in the world.
The world is changing. US unipolar empire is falling and new multipolar empires are rising. At the same time, the US will drag Europe down in the fall and destroy Europe as a flourishing continent, only because of insane hatred towards Russia.
The new year therefore does not seem to offer anything good for many nations, but only continued with conflict and disaster. Fireworks with all its noise are therefore no longer part of entertainment in my mind, but a reminder of war with destruction, killings and mutilations.

This recording was made in my backyard, between houses with LCT540s in IRT. You can hear that the echo time is short. Some might think it’s because I used a Limiter. But the Limiter was turned off, as always should be done when recording fireworks. Recording sound pressure rose to a peak of +7.7dB (-7.4 LUFS-S) .
Details that can often be heard in fireworks when they are launched are not heard clearly in this recording because they were launched from beyond the houses in this backyard. However, I had another microphone set (MKH20/40 parallel AB) close to a place where people were setting off fireworks, but that recording did not go well for various reasons.
Even though this recording has been downgraded to mp3, be careful when listening to this recording. Don´t put up the volume, especially not when listening with speakers.
Quality open headphones are recommended while listening at mid/high-level.
Following picture shows the spectrogram of the whole recording this new years eve. But following recording start at 22:30min. Midnight is at 30:00min and the recording end at 52:30min

It doesn’t happen often that my recordings are „interrupted“ by animals. But it happened last weekend when I was recording at my traditional place in Stafholtstungur in western Iceland. This time it was mice that seemed to gnaw the rubber on the tripod or the cables that ran up to the microphones. When the recording had been going on for three hours and it was 3 o’clock in the morning, the commotion in the mice started to keep me awake. It was as if they had gnawed a hole all the way into the windshield. So I went out and gave them a piece of cake next to the microphone stand. That made them stop biting the microphones. Instead, they started gnawing on the cake, which you can clearly hear after I brought the slice of cake.
This is traditional night silence. The background noise is mainly the wind in the leaves as well as the traffic of individual cars several kilometers away. I did not clean the internal mic noise in this recording as there is no need for it. Here it was recorded with 48dB gain on SD788 and in post-processing the volume was increased by +10dB up to peak -5dB.
Quality open headphones are recommended while listening at low to mid volume.

Sólheimar in Grímsnes is a fabulous place. There is an eco village that was founded in 1930. I stayed there for one night on August 16th, 2021 and of course I let the recorder run overnight.
What is remarkable about this place is that it is located in a small shallow valley in the landscape, so there is not much man-made noise from the surrounding countryside.
When I first visited this place 45 years ago, it was not different from many other places or farms in this county. Just several houses and unique tall trees in open moorland.
Today, the landscape and the previous horizon have disappeared by forestry and new houses have been built. The place is therefore unrecognizable from what it was 45 years ago. The natural soundscape has also changed. Previously, this was a favorite land for peacocks, but with the advent of trees and vegetation, it has changed and the number of sparrows has increased.
The silence is interesting in this place. It’s extremely quiet so people can call each other at a considerable distance. Over the night in calm weather, nothing is audible with bare ears. Even though the recording gain has been increased by 70dB. The only occasional sounds come from vegetation, trees or bugs.
But, there is also some background noise at mid-low frequency that slowly changes the pitch during the night. I have noticed this in many quiet recordings and it seems to be slightly different from place to place. It is not possible to tell if it is related to moisture in the air or temperature. In this recording it might be a light breeze in the leaves on the top of the trees or maybe air conditioners in nearby houses. One thing is for sure, this recording was not disturbed by traffic, not even traffic somewhere far away in the county.
However, this „ultra silence“ part is not what can be heard here. Recording begins at a quarter past five. The sun seems to be warming the area, because fly swarms are buzzing in the background.
Birds started to call and sing half an hour earlier and people were clearly waking up.

The natural acoustic in Iceland for 8 months a year is little more than silence or noise created by the wind. It is obvious that my recording collection contains a large amount of this sound of silence. These are usually 6-10 hour long recordings. I usually do not listen to these recordings, but I run them all through a spectrogram to look for something interesting. Sometimes something interesting happens near the microphone, but it is rare. It is usually just different weather and of course the traffic that interrupts almost all recordings except for two to three hours overnight.
It was recently that the musician Hazal Elif Yalvaç contacted me and asked me about all kinds of „wind sounds“. So I searched through the collection, which made me find an interesting recording like this below.
It contains all kinds of wind sounds, both near the microphones and far away. The whole recording sounds like you are in the middle of a huge symphony orchestra. When it is calm and silent you can hear when the frost bites with a tiny „pop sound“. Straws and branches rub together in the wind and the ice breaks in the soil. Literally everything between falling snowflakes to strong winds blowing through tall trees in the distance.
This is a high gain recording (+50dB at rec.+ 20db in post) with microcosmic sound which was recorded in west Iceland 15th of February 2021.
This Gust symphony starts in Larghissimo, so be patient. The tempo will increase within a few minutes.

For several years I have recorded the soundscape at the same spot when I visit a cottage in west Iceland. Every time I record there I get something different and interesting, all year around.  Forestry has changed the birdlife a lot on this spot in the last 20 years.  Birds like Redwings, Common Redpoll, Eurasian Wren and Starlings are now in increased numbers since the beginning in this century.
I recorded this spot overnight both 6th and 7th of July 2021.
Lot of chicks had already left the nests so the grass field around the microphones was full of birds searching for insects which can be heard in this recording.
The following recording is not an example of the „best part“ which I record these two mornings. It is just a part of the first WAV file at the 6th which I choose because of low traffic. So more of these two days’ recordings will be audible in this blog in the future.
The time is between 2:30 am to 3:05. It is calm and quiet in the beginning until the Common Snipe begins to make a noise with its tail. Young Redwings, Common Redshanks and Snipes are all around the microphones. Other birds are not far away such as European Golden Plovers, Whimbrel, White Wagtail, Eurasian Wren, Rock Ptarmigan, and Whooper Swans in the distance.
This was recorded with four channel IRT setup, but sadly one of the cable was broken so I could only use three of the channels which was though easy to mix into INA-3
This was recorded at 48dB gain (HPF@80hz). In post the gain was increased about 30dB plus gentle RX noise reduction.
Quality headphones are recommended while listening at low or mid level or in speaker at low level.
