As my own minor correction: I'd prefer to say that 'apply' here might be
better used to mean the decision of the person who wants to analyse or
assess the behaviour. On that basis, I'd say that it generally makes little
sense to try to apply characteristic impedance as your analysis model to
domestic analogue audio cables if only dealing with audible signals. There
are much simpler methods.

Slainte,

it's just that it's
irrelevant for analogue audio frequency signals on the sort of lengths
used domestically. If you were to be setting up analogue music-lines as
the Post Office had up to a few years ago when distances could be many
hundreds of kilometres, it was certainly relevant.
