Momentary Quality of Experience: Users' Audio Quality Preferences Measured Under Different Presentation Conditions

Subjective evaluation of audio, video, and audiovisual material is typically performed in a static manner, after the sample has finished. This way, the possible temporal variability of the stimulus quality and its impact on quality perception are ignored. In this study, a new technique for momentary quality assessment was used in order to investigate the effect of content coherence/continuity as well as the influence of video stream on audio quality preferences. Obtained results show that the quality requirements are lower when the presented material is played in a continuous manner than when the same clip is cut into segments that are reproduced in a random order with short pauses in between. This may mean that subjective studies that use short audio stimuli extracted from long-duration content generate results that exaggerate the actual quality needs of consumers. Moreover, it has been shown that subjects’ quality preferences are higher when audio is played without the presence of an accompanying visual stimulus.
