How do capacitors affect tone in electronics?
I’m not sure what you mean by “confusing explanation”. Below is the legitimate explanation. Audio is composed of a wide range of audible frequencies. Low frequencies make audio sound low pitched. High frequencies make audio sound high pitched. Capacitors have impedance that restricts the flow of alternating current. This impedance is called capacitive reactance. Capacitive reactance is inversely proportional to frequency. That means that capacitance reactance decreases as frequency increases. If a capacitor is connected in series between the input and output, then it will pass high frequency signals and block low frequency signals. This makes the audio output sound high pitched. If a capacitor is connected in parallel between the input and output, it will shunt high frequency signals away from the output and allow low frequencies to reach the output. This makes the audio output sound low pitched.
