Ringing can affect audio equipment in a number of ways. Audio amplifiers can produce ringing depending on their design, although the transients that can produce such ringing rarely occur in audio signals.

Ringing can be undesirable because it causes extra current to flow, thereby wasting energy and causing extra heating of the components; it can cause unwanted 188:, a resistor cannot simultaneously critically damp the response and perfectly match the impedance without losing some power on the series resistor, so a 19:
