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.

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.
