I want to make (in CEP) a 20Hz to 20kHz bandpass filter to apply to my vinyl captures but I have 3 questions about filtering.

1. What is better suited for this purpose, an FFT filter or one of the scientific filters (e.g. Butterworth)?

2. Is there anything wrong with making it a brickwall filter or should the filter cutoff be gradual, e.g making the lower cutoff transition band start at 30Hz (100%) and finish at 20Hz (0%)?

3. Is it better to do a high pass filter then a low pass filter or a single bandpass filter?

Thanks in advance for any guidance.
