It is true that most electronics is either capacitively coupled, giving
a DC gain of zero, or uses some method to reduce the DC gain to 1.
But the signal caused by a warp is usually somewhere in the 5-20Hz range,
and most electronics will amplify that just as well as a 30Hz musical note.
If you want music to be passed while warp signals are attenuated, you need
a filter designed for that, with a fairly sharp cutoff.
