Tree ears recording at Vestvolden April 20th 2015

This is a nature recording from a sunny day at Vestvolden  (near Husum S-train station and Kagsmosen) in Copenhagen April 20th, 2015.

Spring is very fresh now. Leafs are unfolding and things are really starting to grow.

The 25 minutes unattended recording is captured with my tree ears setup, now with updated ear geometries to better match my own ears.

With this setup, I am starting to get satisfied, being able to capture a soundscape in an authentic manner – at least that’s how it sounds to my ears and with my headphones…

I am not really seeking any special sounds, I just want to find a nice place out in nature, sit there relaxed with sharp ears, listen to the air and sense the color of the background noise. Often when I see an old painting or photo of a landscape I try to imaging how the soundscape would have been. To be able to hear this would add something extra to these pictures, even though not much sound may be heard.

Equalization of the binaural sound
I’m in doubt how much post equalization is needed for the binarual in ear recordings. Theoretically, it makes sense to compensate for the average characteristic frequency gain of binaural ears, which has strong peak in the range of 2.7 – 7khz (Diffuse field EQ). This produces an overall flat response. But after listening to a few binaural nature recordings it appears that this extra frequency gain actually gives a tremendous natural presence, which can be useful for silent and far distance recordings. So maybe it is a matter of taste from recording to recording how much EQ is needed.
This enhanced hearing capabilities (by leaving out post EQ) feels a bit like hearing the forest with younger and sharper ears.

Another factor is how to handle the low frequency rumble from traffic and similar. I have noticed this bass boom varies quite a lot on different headphones. Leaving the deep bass as recorded seems to produce way to much rumble probably due to most headphones have been designed with exaggerated bass output.

For the present recording, I have applied an substantial low frequency roll off and also a milder compensation in the 2-7kHz range as seen below.

  1. You now seem to be happy with your latest pair of ears!

    Personally, I’m not a fan of binaural recordings, as to me they all seem to be weak in the central portion of the stereo field, as I felt this was the case here also. Nevertheless, I liked the natural ambience you managed to capture.


  2. I do agree that the fully binaural method produces a quite different stereo image compared to the more clean microphone setups, and especially outdoor, the channel separation could be too much. Also not 100% happy with the bouncy frequency curve. Im trying it out at the moment, to see if I could find some good modifications that could produce something interesting.
