Comparison of Spatial Sound Recording Techniques with Usage of Ambisonics and Object-based Audio
Abstract
In this article spatial audio recording techniques are compared: scene-based audio and object-based audio. The study involved mixing recordings from a higher-order ambisonic microphone and support microphones, ambisonically encoded on a virtual sphere. The recordings were combined in different spatial resolution variations by manipulating the ambisonic order. A MUSHRA-like test was conducted, taking into consideration the room divergence effect. The experiment used binaural rendering with headtracking. The results were analyzed using linear mixed models, providing insights into spatial audio recording techniques.
