IMG_2200

World Oceans Day takes place every 8 June. It has been celebrated unofficially since its original proposal in 1992 by Canada’s International Centre for Ocean Development (ICOD) and the Ocean Institute of Canada (OIC) at the Earth Summit – UN Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil.[1] The Brundtland Commission, i.e. the World Commission on Environment and Development, provided the inspiration for a global oceans day. The 1987 Brundtland Report noted that the ocean sector lacked a strong voice compared to other sectors. At the first World Oceans Day in 1992, the objectives were to move the oceans from the sidelines to the center of the intergovernmental and NGO discussions and policy and to strengthen the voice of ocean and coastal constituencies world wide.
The Ocean Project, working in partnership with leading organizations from all sectors, including the World Ocean Network, Association of Zoos and Aquariums, and many others in its network of 2,000 organizations, has been promoting World Oceans Day since 2002 and together with World Ocean Network led a three-year global petition movement to secure official UN recognition. World Oceans Day was officially recognized by the United Nations in late 2008.[2]
World Oceans Day events are celebrated on 8 June, the closest weekend, the week, and the month of June. The day is marked in a variety of ways, including launching new campaigns and initiatives, special events at aquariums and zoos, outdoor explorations, aquatic and beach cleanups, educational and conservation action programs, art contests, film festivals, and sustainable seafood events. Youth have been playing an increasingly important role since 2015, including the development in 2016 of a World Oceans Day Youth Advisory Council (Wikipedia).
The following recording was recorded at midnight 29th of May in a wonderful weather nearby Hraunhafnartanga peninsula, close by the arctic circle.
Quality open headphones are recommended while listening at low to mid level, or in speakers at medium level.

The Jellyfish at Hesteyri

Posted in Náttúra, tagged , , , , , , , , , , , on 11.8.2017| Leave a Comment »

IMG_2200

First weekend of August I traveled to Ísafjörður in the northwest of Iceland. From Isafjörður I took a daytrip with a boat over to Hesteyri which is located in a nature reserve named Jökulfirðir.
The weather was splendid so it was ideal to bring the recording gear with me and record the atmosphere at Hesteyri. This time I brought with me my newest mic setup I built inside Rycote stereo AG windshield. It is a 40cm spaced AB rig (AB40), a two stereo channels with parallel MKH8020/8040, which is slightly angled outward (around °5).
In Hesteyri I record in several places in a small area. Two of them was on the beach where the waves gently plays the music on the coastline during the rising tide. One of this recording is posted here below.
The wind was about 3-6 m/sec, blowing parallel among the coastline so the wind hit only the other side of the windshield, not front of it.
I used MixPre6. The gain was at 50dB, High pass filter on MKH8020 was 120Hz and on MKH8040 80Hz.
The microphones were placed on tripod 60cm above the ground. During the recording the tide rise so in the end the waves went under the rig.
Background noise is mostly the sea waves further outside the fjord and rivers behind and allaround the fjord. Sometimes the boat is knocking on the pier, 200 m away on the left side.
In post I lower the gain -5dB on MKH8020 and rise the gain +5dB on MKH8040 to keep the audible gain between the mics close to be equal. Use again Hi-Pass filter at 100Hz to minimize wind rumbling noise. and then normalized all three audio clips to 0dB. No low pass filter or noise reduction was used.
Both MKH8020 and MKH8040 sounds pretty similar in this recording, so I guess someone will ask:“ Why use four mics when two seems to be fine?“ “ Why making this four channel rig with this expensive mics?“ The short answer is this. The 8020´s are detecting sound from all 360° while 8040´s is only detecting 180° front of the rig. So if there was something behind the rig, like traffic noise it would been clearly audible with 8020´s, but far less with 8040´s. At this time (in Hesteyri) it was only a silence behind the rig so this is not a ideal recording for omni – cardioid comparison.
Field recording is mostly „once in a time – moment capturing“. So having a two different stereo recording of the same event, it is more likely either recording is OK. Two different recordings also give several opportunities in post.

DPA4060 „binaural“ test

Posted in Óflokkað, tagged , , , , , , , , on 10.7.2016| Leave a Comment »

IMG_2200

When I use boom in recording I have used Audio Technica BP4025 stereo mic in Rycote windshield. It is not too heavy and it gives me stereo recordings. But very often I have been disappointed with the „musical“ sound quality, so I don´t often get quality ambiance recordings with this setup. Saying that, it does not mean BP4025 is a bad mic. BP4025 has a very low noise floor. It is the perfect mic for special circumstances like where size does matter and for very quiet environment/nature recordings.
DPA4060 is a pretty sounding miniature mic, sold in pairs and much lighter than any original stereo mic on the market. That means it is perfect to use for boom recordings. But because DPA4060 is an omni mic it is necessary to separate the capsules to get stereo. It is done in two ways. Separate the capsules with space (around 40cm) to get time difference, or place them in two sides of some sonic baffle materials.
The BP4025 was in a short Rycote WS2 windshield which has overall length (wide) 34cm. So it was important to place the capsules each side of some baffle material to get acceptable wide stereo.
I end up with a simple „binaural“ project I made out of wooden leftover (see pictures).
I decided not to use silicon artificial human ears because the ears will change the frequency curve at 2,5Khz and 5,5Khz, which means I needed to fix the EQ afterwards on all recordings made with this rig.
The result was stunning. The rig I made was lighter and better wight balanced than previous BP4025 setup. The overall wight is only 750gr (mics+wood baffle+WS2 basked+fur). It also gives me wider „stereo image“. But best of all, it withstands wind- and handling noise much better than previous BP4025 setup.
Following recordings are 4 and were made in three locations. The two first one are waves on seashore, then one from a cliff, 300 m above sea level with seabirds and the last one is from a football game in Reykjavik. All where recorded on Sound devices 744.
All recordings are straight from the recorder. Just cut and paste, fade in and out and then down grade from WAV to mp3.

(256kbps / 29Mb)

The two first recordings are big and then small waves. The mic have fur, HPF is off and gain at 45db. The mics are faced from the beach to the fjords. You will hear car pass by „behind“ the mic. Notice, you will hear a short „drop out“ when it pass. It is because it passes my car which was located on the road side. See location.
In the cliff recording the mic is without fur. It is possible to hear how strong gust sounds on the Rycote basket, but that is anyway much better (or different) than the my previous BP4025 setup. HPF at 40Hz and gain at 45dB. The boom with the mic reaches the cliff edge about one meter. See location.
The last recording is from a football game celebration in downtown Reykjavik. No fur, HPF at 40Hz and gain at 40dB. The mic stood on a boom about 1 meter above the crowds head. See location.

The fountain in Stapavik

IMG_8941

Everyone who has travelled on road no.1 between Höfn and Djúpivogur in the east Iceland know the road at Hvalnes- and Þvottárskriður. These places are a huge mountain landslide with cliffs above and below the road. Many days when the weather is bad, with heavy rain or strong wind it can be dangerous to pass the road trough this landslide. Some days the road is closed.
This road at Hvalnes and Þvottárskriður was built 1981, but before, the road lied through difficult valley, high in the mountain named Lónsheiði.
Until 1981 it was unusual to pass this landslide, even the beautiful coast below.
The north Atlantic ocean surf is heavy on the miscellaneous beach which has beautiful gravel beaches and huge cliffs and rocks.
Just below Þrottárskriður landslide is Stapavík, a beautiful gravel beach with high rock in the middle, like a huge stoned giant or troll. Along the beach are low cliffs where fresh water seeps out between the geologic age and wets the rocks.
The following recording was made near one of this place where the fresh water is dripping of the rock down to the gravel below.
Quality headphones are recommended while listening at medium level.

Lindin í Stapavík

Fyrir neðan Þvottárskriður, austur af Hvalnesskriðum, er nokkuð löng malarfjara sem heitir Stapavík. Þessi vík eða fjara skartar gríðarstórum stapa sem minnir á steinrunnið tröll. Stapavík er meira og minna umgirt tiltölulega lágum klettum og skriðum. Þar má víða sjá ferskt vatn streyma undan jarðlögunum og niður klettana.
Upptakan hér fyrir neðan var tekin upp á einum slíkum stað í júní 2014 þar sem vatnið seitlar niður klettavegginn og niður í fjörumölina. Í bakgrunni, bak við malarkamb, má heyra í þungri úthafsöldunni þegar hún skellur á fjörunni í gríð og erg, eins og hún hefur gert á þessum stað í árþúsundir.
Mælt er með því að hlusta á þessa upptöku í góðum heyrnartólum og á miðlungs hljóðstyrk.

The dock at Holtstangi. Part 1

Posted in Náttúra, tagged , , , , , , , , , , on 1.11.2013| 1 Comment »

IMG_5583

In Önundarfjörður (fjord) northwest of Iceland is a small village, Flateyri. During the winter, avalanches are falling in the mountains all around the fjord.
In Oktober 1995 a huge avalanche hit Flateyri. Many houses were wiped away and 20 died. Several other avalanches and the crazy weather closed the road to the village so the only way for rescue team was from sea.
The first rescue unit pass a molded 45 years old dock in the bottom of the fjord at Holtstangi. This dock was made in 1950 for security reason if avalanches close the road and other communication to Flateyri
This terrible avalanche in the October night 1995, shows how important this dock was for the community, so it was rebuilt in the spring 1996.
This recording was made in the beach close to this dock 19th of June 2012

Bryggjan við Holtstanga 1. hluti

Ferjubryggja hefur lengið verið að Holti í Önundarfirði. Bryggjan var og er fyrst og fremst öryggisaðstaða fyrir Flateyringa, vegna þess hvað vegasamband um Hvilftarhlíð er ótryggt vegna snjóflóðahættu. Kom notagildi hennar berlega í ljós þegar snjóflóðið féll á Flateyri í október 1995.
Bryggjan var þá orðin 45 ára gömul og mikið fúin. Var því gripið til þess ráðs um vorið 1996 að endurbyggja bryggjuna og þá úr fúavörðum viði.
Hljóðritið sem hér má heyra ver tekið upp um miðnætti í fjörunni við hliðina á bryggjuni 19. júní 2012.

Rumbling noise from Mordor

Posted in Mannlíf, Náttúra, tagged , , , , , , , , , on 16.5.2013| 1 Comment »

IMG_0631

At 13th of May I cycled to the shore, west side of Reykjavik to make some microphones setup test in quiet environment. It was sunny and calm, but cold as it has been all this year’s spring.
This coastline is mostly unspoiled from humans works so there is miscellaneous birdlife. Along is a very popular walking and cycle path. Some places can be very quiet like the beach south of Skildinganes where I have recorded many times nature sounds…as far as it goes.
As usual where nature are close to humans automotive world there is a deep rumbling noise, a terrifying noise from burning fossil fuel. It does not only disturb my ears or recordings, it is a very clear warning about our stupid lifestyle that will sooner or later destroy our planet within a century.

Drunurnar frá Mordor

Upptaka af notalegri vorstemmningu í Grófinni sunnan við Skeljanes.
En í bakgrunni heyrast drunur frá vítisvélum borgarbúa sem fyrr en síðar munu breyta þessum ljúfu vorhljóðum í fjörunni.

Black legged Kittiwake at Arnarstapi

Posted in Náttúra, tagged , , , , , , on 15.12.2012| 6 Comments »

Arnarstapi

In middle of July my family went in a five days trip around Snæfellsnes peninsula. Of course my recorder follow me as a puppy and I recorded as much as I could days and nights. One of this recordings I made was above a cliff score near Arnarstapi.
The weather was very nice, sunny but a breeze from north-vest so it was calm in the cliffs south of Arnarstapi.
I expanded my boom over the cliff brink and located the microphone in a calm place.
And…. WOW! I got really beautiful ambiance. About 15-20 meters below, the sea wave smoothly stroke the cliffs. Whine black legged Kittiwake flew all around and the cliffs were full of the their tweedy baby’s.
During one hour recording I was totally raped on the cliff edge in this beautiful ambiance.
Close by in next score,  fishermens were working at the dock and some tourist walked by behind me.

Rita við Arnarstapa

Um miðjan júlí 2012 fór fjölskyldan í fimm daga ferðalag umhverfis Snæfellsnes. Eins og venja var fylgdi upptökutækið með við hvert fótmál.
Skemmtilegasta hljóðritið sem ég náði í þessari ferð var við Arnarstapa. Ekki að furða því þar er af nægu að taka. Hefði ég getað verið þar við hljóðritanir í marga daga.
Sunnan við löndunarbryggjuna er lítil klettaskora sem gefur skemmtilegan endurhljóm. Teygði ég þar hljóðnemann fram yfir klettabrúnina. Opnaðist þá afar skemmtilegur hljóðheimur sem varð til þess að ég steingleymdi mér í um klukkutíma án þess að hreyfa legg eða lið.
Allt um kring flaug rita vælandi í dagsins önn og á klettasillum mátti sjá og heyra að mikið var af ungum. Fyrir neðan hjalaði svo aldan blíðlega við klettana.
Í bakgrunni má hyra í erlendum ferðamönnum staldra við, spjalla og taka myndir. Þá heyrist einnig umgangur frá bryggjunni þar sem verið var að landa afla og eitthvað í þotuumferð.

Skepnurnar í lauginni

Posted in Náttúra, tagged , , , , , , , , , , , , , , , on 5.4.2012| Leave a Comment »

Í fjöruborðinu fyrir neðan Europe Villa Cortes GL hótelið á Tenerife er sjávarlaug. Sá ég fáar manneskjur synda í þessari laug. Hún leit því út fyrir að vera frekar líflaus. En þegar betur var að gáð var hún full af lífi. Í lauginni var urmull krabba, snigla og annarra kvikinda sem ég kann lítil deili á.
Síðla dags þann 22. desember 2011, rétt fyrir sólsetur, stakk ég hljóðnemum í laugina og gleymdi mér í rúman klukkutíma við að hlusta á einhver kvikindi gefa frá sér hljóð. Í bland við öldunið og fótatak fólks sem gekk um laugarbakkann mátti heyra ýmis hljóð. Öðru hvoru skvettust öldur inn í laugina en háværastir voru líklega sniglar sem nörtuðu botn og veggi laugarinnar í ætisleit.

Creatures in the pool

In the beach below the Hotel “Europe Villa Cortes GL” at Tenerife is a sea pool. It was probably build some years ago for people to swim, but today it is full of all kinds of algae, snails, crabs and other creatures, so it looks not popular for humans.
In the afternoon at 22 of December 2011, I put hydrophone in the pool and recorded more than one hour of mystique sound. Most audible sound are rumbling sound from the surf. Sometimes the waves goes all the way in the pool with splashing sound and sometimes footsteps can be heard when people walk by the pool side. But there is also many other sounds from organic creatures, most likely from hungry snails scratching the pool surface.
