Quite simply, there are few musical signals with a content

There are, however, plenty of EMI signals with a content
above 20kHz and the wires to those transducers might very
well pick them up.

With 192 kHz sampling and a 20 kHz signal, you don't need a
very sophisticated or expensive antialiasing filter, but not
having one at all is like playing with fire; eventually you
will get burned.
