In audio systems, DC components affect the quality of the desired signal by introducing noise. Furthermore, DC signals affect the performance of power amplifiers and increase distortion. In circuits, a coupling capacitor is connected in series with the signal path. ... high current, and audio decoupling applications. Conclusion.
Coupling & Bypass Capacitors

2.0 - Coupling Capacitors. The purpose of a coupling cap is to pass the wanted audio (AC) signal, while blocking any DC from preceding stages or source components. DC will cause pots to become noisy (scratching noises when operate), and cause relatively loud clicks when (if) muting relays or similar are used.

DC signals will come from places like sequencers, offset generators, or LFOs: unlike audio oscillators, they’re static and they don’t move (or least not very fast). And if an input is DC coupled, you can put a slow or static signal into it; if an output is DC coupled, it’s good for that sort of signal. A DC-coupled input is pretty simple.

A decoupling capacitor (also called a bypass capacitor) is a capacitor which is used to decouple AC signals from a DC signal. While coupling capacitors are used to pass through the AC component while blocking the DC component, a decoupling capacitor removes the AC component, making for a more pure DC component. Use of Decoupling Capacitors.

The decoupling capacitor acts as a practical short-circuit to any AC noise voltage, while not affecting DC voltage signals between those two points at all. So long as the decoupling capacitor value is significantly larger than the stray “coupling” capacitance between the cable’s conductors, the AC noise voltage will be held to a minimum.
