The Decca Tree setup evolved from the idea of a minimal recording technique using a pair of microphones. The first system was developed by Roy Wallace. The microphone triangle was placed about 3 to 3.6 m high above the stage level, near the conductor. The microphone system is not properly in front of the orchestra, but more "into" the orchestra.
A Soundfield microphone kit, consisting of the microphone and a signal processor, produces two distinct sets of audio signals called A-Format and B-Format. The sound processor may be either dedicated hardware, or a computer running software. The software processing may be done in real-time during the recording, or later offline.
The array is oriented so that the line bisecting the angle between the two microphones points towards the sound source to be recorded (see diagram). The pickup patterns of the pair, combined with their positioning, delivers a high degree of stereo separation in the source signal, as well as the room ambiance.
