    %X Among the spatial audio reproduction techniques, the ambisonic approach is based on a spherical harmonics sound field decomposition. By truncating the decomposition to the Mth order, a finite number of ambisonic components that form the spatial ambisonic format remains and gives a partial recreation of the sound field. The higher the order M is, the more accurate the sound field is reproduced. Microphone arrays are used to encode natural sound field into spatial components. The encoded sound field is then decoded for a dedicated reproduction system. The goal of this study was to evaluate the influence of these devices. In a first experiment, four ambisonic microphones (from first to fourth order) were evaluated. Six sound scenes were reproduced over a fixed loudspeaker setup. In a second experiment, synthetic encoding processes from first to fourth order were reproduced on different loudspeaker configurations. Besides the ambisonic order, the encoding and reproduction systems also had a perceived influence on the reproduced sound field.
