LSB Audio has been collaborating with researchers at the University of Colorado to determine how audio artifacts can impact perceived video quality.  The results of this study will be presented at the 128th Audio Engineering Society Convention in London (May 22-25, 2010).

As the audio, video, and related industries work toward establishing standards for subjective measures of audio/video quality, more information is needed to understand subjective audio/video interactions. This paper reports a contribution to this effort that aims to extend previous studies, which show that audio and video quality influence each other and that some audio artifacts affect overall quality more than others. In the current study, these findings are combined in a new experiment designed to reveal how individual impairments of audio affect perceived video quality. Our results show that some audio artifacts enhance the ability to identify video artifacts, while others make discrimination more difficult.
