Hi! I’m designing an audio plugin and it uses filters from Juce. Now the shape of a bandpass filter looks like the one in the first picture. However I’d like to implement the filter with the shape of the second picture. How to do that? Can I do this with existing Juce classes?
Thanks!
You can model that sort of shape with a pair of filters, a high pass filter to remove the lower frequencies, and a low pass filter to remove the higher frequencies, keep their cutoff frequencies apart to give you the bandpass.
Or with more than one bandpass in series, but you have to get the spacing of the centre frequencies right to get a flat top.
Thanks for the answers! I’d like to clarify my question - the top of the shape doesn’t have to be super flat. It can be a little bit rounded as long it’s not that sharp as in the first picture. I found some information about this, and Butterworth bandpass could do the trick. But I can’t find it in Juce. Propable not available in Juce as standard?
