Exploratory Studies on Perceptual Stationarity in Listening Test - Part II: Synthetic Signals with Time Varying Artifacts

Many recent publications related to audio coding use the recommendation "MUltiple Stimuli with Hidden Reference and Anchor" (MUSHRA; ITU-R BS.1534-1) for the evaluation of subjective audio quality. Judging the quality of multiple conditions can be inconclusive if the employed test excerpts exhibit more than one prevalent artifact. Two papers investigate the impact of time varying artifacts in both, synthetic and real world signals and claim "perceptual stationarity" as a requirement for test sequences used in MUSHRA tests. This second part focuses on the alternation of multiple types of artifacts in one item and the differences in the ratings compared to items which only contain one of the respective types. It furthermore discusses the meaning of the temporal position of artifacts in an item.
