The Recording Angle - Based on Localisation Curves

Authors: Wittek, Helmut; Theile, Günther

AES Convention 112 · Paper 5568 · April 2002

Abstract

The useful pick-up sector of a stereophonic microphone is indicated by the recording angle. It is based on phantom source shift data due to resulting inter-channel level and/or time differences. However, in related literature the recording angles of known microphones such as XY, Blumlein, AB, ORTF, OCT, etc. are differing because they are determined from different interpretations of these data. It is proposed to rest on the so-called localisation curve, which describes the directional translation of sound sources within the loudspeaker basis and corresponds with directional balancing results in practical recording situations. The newly defined "Recording Angle_75%" is proposed to be the suitable key value in the Tonmeisters' practice.
