RE: That video

The McGurk effect and your examples from Poppy Crum are specifically related to speech recognition. I think it is well known that we utilize a wide variety of audible and non-audible cues to understand each other in conversation. We don't just listen to the articulation of words, we also make use of what sentence/context they are used, vocal inflections, tone of voice, accent, lip movements, body language, conversational context, feelings about the person speaking, and so on. Our use of all these cues makes our speech recognition ability a lot more robust than it would be if we only listened to pronunciation.

But I fail to see what relevance this has to blind testing of audio components. In the McGurk video and Poppy's Zeppelin clip, the visual cues are directly correlated with and related to the audio. The brain is "tricked" because it is presented with simultaneous inputs that are correlated but conflicting, and has to choose. There is nothing remotely like that in our music systems, which remain visually static when playing music. And Poppy's "legislatures" clip is about masking, there is no visual component to it.

You and 3db are implying that because we utilize non-auditory cues as part of speech recognition, that we must also use non-auditory cues when comparing audio components. But the kind of visual cues used in your examples are not present in sighted listening comparisons of audio components, so there is no logical basis for using these examples to make your point about blind testing.
