It is rear now a days to discover new places without traffic or engine nose. I found one in June 2019. It was at Fellströnd, in the northwest of Iceland. That means I have natural silence for more than a one hour. It is a south part of a peninsula which only have gravel roads and no shopping service so motorist are normally not driving there for pleasure.
Less human traffic means more biodiversity. It thrives better in places with less farming and fast driving cars. One roadkill can as well mean a death of the whole family. Car covered with smashed bugs means less food for birds… and so on. This is clearly visible and audible in those areas which have „industry“ farming and lots of fast driving traffic.
No traffic, or engine noise, means more natural silence and more transparent soundscape. Therefor it is very interesting to listen to this recordings. It is even possible to hear sheep footsteps far away and detect what bird species are in the area, even far away. In fact it is possible to analyze the situation of the biodiversity.
This is a high gain recording, recorded at +50dB. Gain was then increased in post about +25dB, normalized at -8dB and gently NR.
This is a part of 10 hour recording. This part was recorded between 7 and 8 in the morning at 21st of June.
Many bird species are audible in this recording. Black tailed Godwit, Common Redsank, Whimprel, Red necked Phalarope, Eurasian Oystercatcher, Common Ringed Plover, European Golden Plover, Dunlin, Raven, Redwing, Purple Sandpiper, Meadow Pipit, Geylag Goose, Whooper Swan, Red Throated Diver and Common Eider. I am almost sure I have not counted them all.
You can hear sheep footsteps which was though far away, also birds wing flaps as a low rumble noise.
Quality open headphones are recommended while listening at low or medium level.

Starling Starri

It has been my work passing weekends recording birds and other sounds in my garden. Sometimes I am just testing microphones, microphones’ setups, wind protections or batteries. Sometimes I am just hoping to get something unusual, car crash in the neighborhood, earthquake or just something nice and interesting.
This recordings could be many hours long. Then usually this recordings go through different audio software and spectrum analyzer. If nothing interesting is found then most of the files are deleted. Most of them are just traffic noises.
I am used to feed birds in my garden so they are an ideal sound source and the following recording is one of this feeding day in November.
After almost four hours recordings a very big group of Starlings visited my garden. They fly and walk around the microphones. A raven was not far away and frightened most of the starlings when he flew close by.
For many reasons this is a nice recording, but for one reason I was not satisfied with the result.
I will let the listeners to find out what it is and discuss it and response. I will give my answer before Xmas.

Umferð starra

Ég hef gert mikið af því undanfarnar helgar að taka upp umhverfishljóð úti í garði. Oft er ég að prófa hljóðnema, hljóðnemauppsetningar, vindhlífar eða rafhlöður. Oftar en ekki eru spörfuglar sem ég fóðra úti í garði viðfangsefnið þó ég láti mig alltaf dreyma um hið óvænta. Þessar upptökur geta verið margra klukkustunda langar og fátt annað á þeim en hávaðasöm bílaumferð. En áður en upptökunum er hent er þeim rennt í gegnum forrit sem sýna í fljótheitum hvort eitthvað áhugavert sé á þeim að finna. Ef svo er þá er það geymt.
Hér er á ferðinni eins slík upptaka. Eftir nærri fjögurra klukkustunda upptöku kom stór starrahópur í fóðrið sem lagt hafði verið fyrir þá.
Þarna spígspora og flögra fuglarnir umhverfis hljóðnemana, en stór hópur þeirra er uppi í trjánum. Hrafn er í hverfinu og fær hund til að gelta og hræðir síðan fuglana þegar hann flýgur of nærri.
Þetta er að mörgu leyti lífleg og skemmtileg upptaka. En það var eitt atriði sem varð til þess að ég var nærri búinn að henda þessari upptöku.
Ég ætla ekki að segja hvað það er, en ætla að lát hlustendum eftir að dæma upptökuna og segja frá því hvað hafi hugsanlega misfarist og fá þá til að rita ummæli hér fyrir neðan. Ég mun svo segja hvað mér finnst fyrir jól.
