Fukada Tree

Fukada Tree

When you look at the Fukada tree setup, you immediately think of a Decca tree.
The main difference, though, is that it uses cardioid microphones instead of omnidirectional ones in the Decca tree.
There are also two additional omnis used as outriggers, which are mixed between the front and rear channels. These microphones are intended to compensate for the lack of low frequencies picked up by the cardioid microphones and to add more spaciousness to the recording.
Using cardioids instead of omnis reduces crosstalk from the front sound to the rear loudspeakers.

Although it is an older model, it is still a great setup for recording immersive audio. Developed by Mr. Akira Fukada in 1997, it is still a great setup. It really shines when combined with a Hamasaki square, a Theile trapezoid or other setups for recording the rear space and/or ambience.

This is the setup of a Fukada Tree you will mostly find:

You can and should adjust the distance between the front and rear microphones according to the room in which you are recording, but 180 cm are a good point to start.

Mr. Fukada continued to optimize this setup, so you will find other alternatives like this one for example
