Hello Sampsa
Welcome to the loony-bin.This bypass thing took me a while to get my head round, due to the misuses of English by certain foriengers :¬).
But the process does NOT "bypass" anything, its a process to overcome the intrinsic short commings of a device, for example the capacitor.
Like most real devices thay have their design limitations due to phyical constuctions. An Electrolytic capacitor is quite good at its job at low frequencies but at higher frequencies the capactor becomes an inductor whose impeadance increases with frequency:- the exact opposite of what a cap should do.
So to overcome this you place a small suitable high frequency cap in parallel with the eletrolytic so that the high frequencies get shunted correctly. A simulat process happens with a hf cap that doesnt work too well at lower frequnces.
Now as to that with which to "shunt" aka *bypass* (in american) with and its audio and sound implications is a fierce topic of discussion.Now just watch out for the blue pills. the red ones are ok-ish.
