I have an interest in audio but a hard time understanding how the electronics really work. I only took half a year of electronics when I was in highschool and that was over a decade ago.
When it comes to electrolytic capacitors, I have a general understanding that the hold a charge, can dissipate a charge, and are unidirectional.
I see in forums and spreadsheets that capacitors are used as a "filter" for frequencies, in that adding one will change what sounds are produced more readily by the speaker driver. I am curious as to why this is.
1. Audio signals are more or less AC, so wouldn't that mean the capacitor is being harmed by the opposing flow of electrons?
2. If a current is like an electron flow, wouldn't a capacitor be "filled up" and then act like a straight connection - as in, how does it filter if it is "full?"
