How to Build It
- Feed the incoming audio signal through a capacitor.
- Connect the capacitor's output to a resistor, with the resistor's other end to GND — this is the filtered output.
- Take the filtered signal from the junction between the capacitor and resistor.
- Connect the filtered output to an amplifier or headphones.
- Compare with the original signal — low frequencies (the bass) should be noticeably attenuated, while high sounds are emphasized.
