For a +4 dBu sinusoidal signal, that's about 1.23 V peak, for a +14 dBu signal, about 3.9 V peak. The capacitance of class 2 capacitors, especially small SMD types (which are good at filtering RF interference due to their small parasitic inductance), can easily change by a few percent due to such a signal level.
Audiophile Grade Capacitors

The best capacitor types for audio circuits are polystyrene and polypropylene. Polystyrene is the first choice, but are only available in values up to .001 uF. Above that value, polypropylene is the type of choice, with nearly the same qualities of dissipation factor (DF) and dielectric absorption (DA) as polystyrene (these are the two capacitor “qualities” that most …

Anti-aliasing filters are another type of low-pass filter, used in analog-to-digital conversion to condition the analog signal and ensure that it meets the requirements of the sampling theorem. Electronics/Power Circuits: Capacitors can be employed in band-stop circuits to protect delicate electronics. Some devices are sensitive to harmonics in the power supply, …
How to Pick Audio Capacitors – Charrette & Beget

A typical ESR for a capacitor might be .1Ohm, whereas a low ESR model might be .01ohm.Low ESR seems to be a much touted feature for audio capacitors, especially Black Gates. Since resistance is not dependent on frequency, however, I don’t understand how ESR would have any effect on distortion in the audio signal, and I doubt you’re going to hear a difference …

A capacitor is used to filter the DC signal. This can be done by pairing capacitors in series in the circuit. The following circuit is a capacitive high pass filter. This involves blocking signals such as DC or low frequency. A ceramic capacitor with a value of 0.1µF, in general, can be placed following the signal.

Filter capacitors. Capacitors are reactive elements, which make them suitable for use in analog electronic filters. The reason for this is that the impedance of a capacitor is a function of frequency, as explained in the article about impedance and reactance. This means that the effect of a capacitor on a signal is frequency-dependent, a property that is extensively used in filter …
