Butterworth Filter

[Mustang Martigan]

Can you create a Butterworth filter using any EQ plugin? If yes, what would the settings be?

For example, I was reading the description of Brainworx's bx_cleansweep Pro; it mentions that it includes a Butterworth filter. However, the free version, bx_cleansweep v2, doesn't mention anything about the Butterworth.

Sure you can emulate a Butterworth filter in an any decent EQ plugin... What would the settings be? First you would need know what order Butterworth filter you are after as well as what the corner frequency is. It's a bit of a complex equation but basically the higher the order the steeper the curve as it passes through the selected corner frequency.

Once you determine the order type and select your desired corner frequency, I'm not quite sure how you would use the equation to get specific values for the Q and amount of gain cut to punch into your EQ plugin parameters, but you can probably just look at some example curves and approximate it.

In a full mix situation, slight variances in the Q and gain cut between an approximated curve and an actual Butterworth curve probably won't have a substantial delectable effect on a single sound source. However, going for a different order type or changing the corner frequency will make more of an audible difference.

Butterworth is a pretty common filter type, so why not just use one? The DDMF EQ from the Jan 2017 issue of Soundbytes would be a nice choice:

Or just Google “free butterworth equalizer plugin” for a flood of alternatives.
