Cardioid-based surround array

Cardioid-based surround array

This microphone system should be used, when you need a very smooth and equal coverage of the soundscape around you.
As you might have already guessed, this is mainly for 5.x setups.

You might say this setup is similar to a Fukada tree, but it's also different.
In the Fukada Tree, the emphasis on the Decca Tree is more obvious, and there are two "outriggers." This system does not include the two omnidirectional microphones.
But there's absolutely no reason why you shouldn't try adding a spaced pair of omnidirectional microphones to it for a more solid bass.

An example of a possible setup (without the outriggers!) may look like this. You may change the size of the array to your needs.

The numbers shown are theoretically correct, but your mileage may vary. And we find it very hard to adjust a microphone in an angle of 216°. 

However, we will provide a tutorial and a shopping list. Let your ears be the judge.
We will also compare it to an IRT cross setup. 
The obvious advantage of an IRT cross setup is that it only requires four microphones instead of five.

But maybe it's worthwhile adding another microphone and using a bigger recorder? - We will publish some recordings, once we are done.
