This article presents a comparison of spatial sound recording techniques based on scene-based and object-based audio. The study aimed to make different mixes from a recording which consists of a higher-order ambisonic microphone and spot microphones. For spot microphones simple ambisonics encoding was used, which allows panning the individual channels on an ambisonic sphere as objects. Recordings were combined in various variants of spatial resolution, mainly varying the order of ambisonics used. In the next step, a MUSHRA-like test was conducted on a panel of experts in auditory experiments. The experiment was done on headphones using a binaural rendering with three degrees of freedom provided via a head tracker. The findings suggest that the optimal immersion approach involved using individual object stimuli rendered at a 5th-order ambisonic spatial resolution. Regarding the ability to localize sounds, the combination of 3rd-order ambisonic with 5th-order objects yielded the highest performance. Overall, the outcomes of this experiment provide insights into recording and mixing techniques within the field of spatial audio.
