How the low pass filter can be converted into high pass filter?

A lowpass filter can be transformed to a highpass filter by exchanging the resistor and the capacitor. The basic form of the highpass filter is shown in Figure 5-37(B). Again it is assumed that load impedance is high. The pole can also be incorporated into an amplifier circuit.

Can you combine a high and low pass filter?

Filter circuits can be designed to accomplish this task by combining the properties of low-pass and high-pass into a single filter. The result is called a band-pass filter.

How do high pass and low pass filters work?

A high-pass filter (HPF) attenuates content below a cutoff frequency, allowing higher frequencies to pass through the filter. A low-pass filter (LPF) attenuates content above a cutoff frequency, allowing lower frequencies to pass through the filter.

Where should I set my high pass filter?

As a general starting point, you should place a high pass filter on each channel and adjust it according to the lowest frequency the sound source can produce. For example, a male vocal will not contain frequencies lower than about 80 Hz.
