This paper presents a case study of an original electronic music production in stereo and means for then creating an Ambisonic remix. The main goal of this work was to explore the potential for extending all dimensions into extended space. The stereo and Ambisonic mixes, as well as the stereo and binaural renders, were subjectively evaluated by experts performers. When compared, the stereo and Ambisonic mixes differ not only in terms of space but also with regard to the timbre and dynamics. In general, the listeners preferred the spaciousness and selectivity of the Ambisonic version over the stereo. The obtained results are consistent with the outcomes from other studies that focused on the differences between stereo and multichannel reproduction. The most interesting conclusion can be formulated from a comparison between the stereo and binaural renders of the Ambisonic mix. The results clearly show the preference of spaciousness of the binaural version, and the general preference also indicated binaural as preferred. Due to the popularity of headphone playback, the obtained results show the potential of Ambisonic productions with targeted binaural playback.
