Linear ORTF-3D

Linear ORTF-3D

The "Linear ORTF-3D" is based on Schoeps's proven ORTF-3D technique.
It was developed by Felix Krückels (Darmstadt University of Applied Sciences) and Helmut Wittek (Schoeps's CEO).

In scenarios where the microphone's placement precludes a central positioning within the auditory environment, it nevertheless furnishes a realistic and spatiotemporally balanced auditory ambience across eight channels (e.g., for Dolby Atmos).

As the saying goes, a picture is worth a thousand words:

This is how it was developed!

The more interesting view is the graph, with the directions of the microphones.

We would expect that a downward tilt of -20° means this system is intended to be placed quite high up.

We made our very first version of a rebuild and it isn't ready for outdoor use, yet. But it works, even if the microphones are just regular cardioids SDCs.

Without any further ado:

The steel eyed readers will notice that these aren't neither super- nor hyper-cardioid microphones. You are very right!

Our hyper-cardioid microphones are currently in use in another array. But when you can build regular ORTF setups with cardioids, why you shouldn't try them in an ORTF-3D linear array? 

If you want to render your recordings in Reaper, HERE is a template for Reaper. You will need the IEM plug-in suite and for your convenience we also provide a template for the IEM MultiEncoder. (As soon as we found it on our computer, we will upload it)
