Warping of the Recording Angle in Ambisonics

ID 22198
Abstract When the main microphone of a recording picks up a musical scene at a recording angle that appears too wide or too narrow in the playback, it is very hard to correct this. To allow modifications in the post-processing of stereo, a sound recording engineer might use coincident microphone arrays as double-MS or the sound field microphone arrays. Higher order Ambisonics also uses array processing, but modification of the recording angle is uncommon, and it has been considered too complicated compared to stereo. This paper shows how to practically achieve warping of the recording angle in the processing of higher order Ambisonic recordings or productions. It concludes with an analytic recurrence scheme that is applicable and easy to implement.
