The paper outlines a process for producing and evaluating two mixes of the same musical composition, "Dancing Ends" by ?ukasz Pieprzyk, using spatial sound technologies: Dolby Atmos and Ambisonics. The composition was recorded using overdub, multitrack techniques and the mixes were assessed through a direct evaluation method based on average ratings on a 1 to 5 scale, in accordance with the ITU-R BS.128 standard. The criteria for evaluation included selectivity, depth, width, and height of the sound stage, sound envelopment, brightness, and localization quality and other aspects specific for the composition. These criteria were assessed in three different listening systems and environments: 5.1, 7.1.4, and binaural. Listening tests revealed a preference for the Dolby Atmos mix across all listening systems, even though the Ambisonic mix received higher ratings in several areas. The test group comprised individuals with higher education in acoustics, basic sound production skills, and experience in listening tests. The results were analyzed using the non-parametric Shapiro-Wilk test and t-Student or Mann-Whitney test.
