This 'memories' theory is a well-established model of how our senses work anyway - your brain synthesises inputs from multiple sources into what feels like a single experience of your surroundings.
This is vital from a survival standpoint because 0.2 seconds of ping between seeing and hearing without your brain telling you they happened simultaneously would be debilitating.
The same thing happens with the sensation of "flavour" (smell + taste).
