Three stereo microphones noise and sensitivity comparison.
Shure VP88 – Rode NT4 – Audio Technica BP4025
This recordings include a spoken word from pocket radio at very low volume and ticking alarm clock in 1,6m distance. The volume settings on the radio was so low, the sound was hardly audible with bare ears. Noise from radiator pipeline is audible in the background. Miscellaneous bird life is outside and should be also clearly audible.
Keep in mind. This test is only noise and sensitivity comparison. High sensitivity and low noise is VERY important for nature recordings. This comparison does not give any information how this microphones sounds for music recording or how they withstand high pressure sound level. See spectrogram and pictures
Quality headphones recommended while listen.
Shure VP88, Rode NT4 and Audio Technica BP4025 direct from recorder. All at same gain level at 55dB.
All three recordings are now independently level normalized up to 0dB.
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.
Every 1st of May is a Labour day parade in Reykjavik, where people walk together to the city center, listening to speeches and music.
For one year ago I walked this parade and listening to the day’s program with binaural microphones. Following recording contains the end of the day’s program and suddenly song and speech income of Iceland’s well known socialist Þorvaldur Þorvaldsson.
Another recording from the parade this day can be found at Audioboo
Verkaliðsdagurinn 1. maí 2012
Verkaliðsdaginn 1. maí, nákvæmlega fyrir ári síðan, mætti ég niður í bæ með Binaural hljóðnema. Ég bjóst ekki við neinu spennandi en lét upptökutækið þó ganga allan tíman. Þegar opinberum ræðuhöldum á Hallærisplaninu lauk tók við söngur Karlakór Reykjavíkur og Léttsveitarinnar. Þar á eftir tók við samsöngur á Internationalinum.
En óvænt í lokin þegar öllu átti að vera lokið kom Þorvaldur Þorvaldsson (Þorvaldur kommi) inn með hressilegan söng og hélt beztu ræðu dagsins.
Önnur upptaka, frá gönguni sjálfri þennan dag er að finna á Audioboo.
This is another ambience recording from the island Flatey in Breiðafjörður, a straight continue of part one.
Women, children as well as the elderly all gather for a boat is docking. Two men, with the day’s catch, step ashore.
When the catch has been divided, the whole throng returns to the village in a cacophony of conversations and drift homewards.
Somewhat nearer, in front of the microphone are a few Red-necked Phalaropes as well as Mallard ducks with ducklings. Other distinguishing birds like the loud Arctic tern and Whimbrel, as well as many other species of bird, can be heard.
Flatey í Breiðafirði 2012. Annar hluti.
Þetta er beint framhald af fyrsta hluta.
Nú safnast allir saman, konur, börn jafnt sem gamalmenni því bátur kemur að landi. Tveir menn með afla dagsins ganga á land. Þegar honum hefur verið skipt, kemur allur manskapurinn aftur inn í þorp með miklu skvaldri þar sem hver fer til síns heima.
Nokkuð nærri, framan við hljóðnemana voru fjörugir Óðinshanar og stokendur með unga. Aðrir háværar tegundir eru háværar s.s. kría og spói auk margra annarra fuglategunda.
During Icelandic independence day, 17. of June 2012, I was in Önundarfjörður fjord in the Westfjords, the north west peninsula of Iceland. This fjord lies deep between steep mountains with high cliffs. After midnight I entered an Arctic tern colony to record their sounds. The recording conditions was as good as it gets. The weather was calm, dry but cloudy, and the temperature was about 7 °C. Almost no traffic was in the fjord so most of the background noise was only coming from falling water in the mountains and sea waves at the shore.
This Arctic tern colony is big and has been there for decades, even centuries. This bird is very territorial and aggressive protecting the colony and many other bird more passive species feel safe to nest among the Arctic tern. So this recording includes sounds from many other bird spaces such as Whimbrel, Black-headed Gull, Black-tailed Godwit, Common Redshank, Oystercatcher, and Golden Plover… and many more
The recording contains also human and sheep voices from a nearby farm. Swans, Red-throat Diver, and common Eider at the shore side and a some sound from a Gull colony high in the cliffs all around the fjord.
During the recording the Arctic Terns attack many times the furry microphones. Sometimes you may hear their excrement fall to the ground around the microphones, but at this time they never hit or peck the Blimps.
The duration of the recording was almost 80 minutes. Following recording contains the last 36 minutes so my disturbing visit is not much audible. This is just a nice ordinary summer night in the north west of Iceland.
Krían í Önundarfirði 17. júní 2012.
Upptaka þessi var gerð í kríuvarpi nærri Holtstanga innst í Önundarfirði.
Veður var stillt, þurrt en skýjað og hiti um 7°C. Það var því varla hægt að kjósa sér ákjósanlegra veður til upptöku á fuglalífi. Allt iðaði af lífi. Fyrir utan kríu mátti sjá og heyra í hettumáfum, spóa, lóu, stelk, tjaldi og fleiri fuglum, Efst í fjöllunum mátti sjá allt fullt af fuglum á sveimi björgunum. Í flæðamálinu voru álftir, lóm og æðarfugl.
In 10th of February 2013 I recorded a concert with Amateur symphony orchestra.
The program contained a wonderful melody “Senur” composed in four chapters by Sigurður Sævarsson. It was composed for string orchestra and obo. Both the orchestra and the soloist, Guðrún Másdóttir, played it flawless. Hereby is the first chapter of Senur without any post work.
I was pretty happy with the recording result, even though the concert hall (a church) sounded terrible for recording. It has a very harsh sound and difficult peaks in some resonance frequencies.
Over the orchestra I used a Jeclin disk with a double pair of mics, parallel MKH8020 and MKH20 in 45°+45° (as shown on the picture).
Close to the soloist there was a pair of MKH8040 and far behind in the hall was a pair of SE4400 with spaced Omni (70cm).
Past months I have got a few emails where people ask me for a sound sample with my Jecklin disk. So here are two samples, both almost the same, but one is recorded with MKH20 in 45°+45° and the other one with parallel MKH8020.
“Senur” fyrsti kafli
Sigurður Sævarsson hóf söngnám við tónlistarskólann í Keflavík undir handleiðslu Árna Sighvatssonar. Þaðan lá leiðinn í Nýja tónlistarskólann, þar sem hann nam hjá Sigurði Demetz Franzyni og Alinu Dubik. Hann lauk þaðan prófi vorið 1994. Sama ár hóf Sigurður söng- og tónlistarnám við Boston University í Bandaríkjunum, þar sem kennarar hans voru William Sharp, Charles Fussel, Sam Hendrick og Martin Amin. Hann lauk þaðan meistaraprófi í báðum greinum vorið 1997.
Helstu viðfangsefni Sigurðar hafa verið óperur og kórverk. Tveir geisladiskar haf verið gefnir út með verkum hans. Hallgrímspassía kom út árið 2010 og Missa Pacis kom út 2011. Nýjasta verk Sigurðar er Jólaóratórían sem var frumflutt 2. desember 2012.
Sigurður samdi “Senur” upphaflega fyrir óbó og strengjakvartett, að tilhlutan Eydísar Franzdóttur óbóleikara. Verkið var frumflutt á Myrkum músíkdögum 2012 og hefur verið flutt nokkrum sinnum síðan í Tékklandi og Þýskalandi. Sigurður umritaði verkið fyrir skömmu fyrir óbó og strengjasveit og er sú gerð verksins frumflutt hér. Guðrún Másdóttir hóf að læra á óbó í Tónskóla Sigursveins D. Kristinssonar 14 ára að aldri. Hún lauk þaðan fullnaðarprófi árið 1992 undir handleiðslu Daða Kolbeinssonar. Hún sótti nær öll námskeið Sinfóníuhljómsveitar æskunnar undir stjórn Paul Zukovsky á árunum 1985-1991 og hefur nokkrum sinnum leikið með Sinfóníuhljómsveit Íslands. Guðrún hefur leikið með Sinfóníuhljómsveit áhugamanna óslitið frá byrjun árs 1991. Hún er í stjórn hljómsveitarinnar og hefur umsjón með vefsíðu hennar, en aðalstarf Guðrúnar er staða tölvunarfræðings hjá fyrirtækinu Mentor.
Flatey is the biggest island in Breiðafjörður bay in the west of Iceland, but nevertheless a small island. It is a wonderful place. Rich, widely spiced bird life and no car traffic. Most houses are old and most of them are nicely rebuilt. No one lives there all year around but in spring, summer and autumn lot of people stays there. Sometimes the place is overcrowded with tourists but there is both a campsite and a hotel.
I spent few hours in Flatey in June 2012 with my family. We just walked around in this relaxing surroundings. The east part of the island was closed because of bird’s hatch and eyas. But the life in the “village” was also interesting.
Strong gust from vest made recording difficult but I found a quiet place beside a wall not far away from the “main street”. In front of me was a small marsh and it was overcrowded with all kinds of birds; snipe, gull, golden plover, white wagtail, oystercatcher, arctic tern, ducks and so on, but closest to the microphone is a red necked phalarope. In distance Kittiwake and other birds are audible.
I was very lucky this time, there were few tourists on the island so the recording contains relaxing conversations between neighbors in this wonderful ambience. In the beginning a child is drumming a box, but it last only for 5 minutes. After that it is possible to listen what people and birds have to say.
Flatey í Breiðafirði 2012. Fyrri partur
Í lok júní fórum við fjölskyldan í dagsferð út í Flatey. Auðvitað lét ég upptökutækin ganga á nokkrum stöðum þótt vindur væri nokkur úr vestri. Ekki bar mikið á fólki eða vélum. Andrúmsloftið var því mjög afslappað.
Inni í miðju þorpi er mýri sem iðaði af fuglalífi. Ég kom því hljóðnemanum í skjól við húsvegg og hljóðritaði stemmninguna í u.þ.b. klukkustund.
