at the very moment an audio signal is fed to the VR & let's also assume that the negative portion was initially introduced to the CC, electrons (as you already know) will accumulate on the plate directly connected to the VR. due to this electrons on the other plate w/c is connected to the base of Q, will be repelled and forced to move towards the base of Q. in …

A capacitor that serves to block DC voltage from AC voltage is known as a coupling capacitor. Microphones also use coupling capacitors to block DC signals from the signal that is being recorded. While the DC signal is needed to power the microphone, only the AC signal is required in the finished audio recording. Segue to the crossover
How to avoid a electrolytic capacitor on a (audio) signal ...

You probably want something that behaves reasonably linearly- while the capacitor won't have any effect on audible signals when the cutoff frequency is chosen properly, if there are sub-audible frequencies present near the cutoff the harmonics could be audible. That would tend to point against ceramic caps, which have a large voltage coefficient.
How to Pick Audio Capacitors – Charrette & Beget
https://www.maxpierson.me/2009/03/17/how-to-pick-audio-capacitors/
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 …

Depending on the construction, sound may be audible emanating from the capacitor, heavily distorted, but audible nonetheless. This can only come from vibration generated in the capacitor by the audio signal. Conversely a capacitor may convert vibration into electrical energy, particularly if the cap is biased by an AC voltage like an audio signal.

It is worth noting that at each stage, you may hear differences in sound, e.g. through capacitors used for filtering, you may get an increase in treble or more bass etc. and coming out of a transistor used as an amplifier, the signal level will become louder. You continue to probe until you come to a point where no audio is present .

Thank you for your inquiry about capacitors in the audio path around our SigmaDSP parts. In general, there are 3 types of capacitors that will be available in the values that are appropriate as AC coupling in most signal paths: electrolytic, tantalum and ceramic. Each has strengths and weaknesses.

To couple with a capacitor in audio usually means just using a low value like 4.7uf because at somewhere between 3000 and 5000 hertz it will have an 8 ohm capacitive reactance and since that matches the speaker it will optimize power transfer.
What is a Coupling Capacitor? - Learning about Electronics
http://www.learningaboutelectronics.com/Articles/What-is-a-coupling-capacitor
Coupling capacitors are useful in many types of circuits where AC signals are the desired signals to be output while DC signals are just used for providing power to certain components in the circuit but should not appear in the output. For example, a coupling capacitor normally is used in an audio circuits, such as a microphone circuit. DC power is used to give power to parts of the …

Some suggest that this is not proper design, others say it's OK because the small voltages of a preamp signal can be reversed through an EL cap. In practice you have to figure out how the dc voltages at the two capacitor terminals are in idle mode. Then you turn the capacitor to match this polarity.
