This is a demonstration of an another variant of the binaural microphone setup presented in the last post. This concept could well be called something like a tree-ears microphone setup. I think it can be useful for many types of nature recordings including for remote unattended recording stations. Furthermore, It should have potential for good sound capturing, being easy to install and stay relatively compact and unnoticed.
Basically, the mechanical parts of this prototype are just the same as used in the previous post. Only now, the two sides are strapped on to a suitable sized tree trunk. Clearly, there is no room for the Earthworks microphones, so I’m using a smaller custom made microphone setup based on the Primo 172 capsules.
Below is a test recording with the setup, directly connected to the microphone inputs of the Microtrack II recorder. It is captured in Ballerup, Denmark November 5th 2014 at sunset – same location as previous post, just 10 minutes after.
Being the first raw take with the setup, only post processed with a low frequency (<30Hz) rumble filter, I think the sound is surprisingly good and with a low noise floor (apart from wind noise). This is also surprising taking into account that this is a set of low cost of the microphones which can be bought for ~£25.
Details about the setup are in the following.
