Default Voltage sensitivity of ceramic capacitors
Il se trouve que Brian Morrison a formulé :

Well known in SM caps with higher dielectrics, it's essentially a
piezo-electric effect.

Noticeable in PLL loop filters, a voltage transient on a tuning step can
be considerably extended and in extreme cases will be microphonic.

AFAIK ceramic capacitors are never used in audio except for RF
bypassing
and in parralel with other types of capacitors.
