Linkwitz Riley Filter Crossover Issue



  • Merry Christmas to everyone!

    Scriptnode Linkwitz Riley Filter doesn't make the crossover (band split) correctly. I used All pass to compensate the phase delay, but you can hear the phase issue while tweaking the "Low Split" knob.

    Any ideas?

  • Any ideas or fixes please? I saw some examples in the forum but none of them is working properly.

    Can we make a proper band split (without phase problem) with Hise? @Christoph-Hart



  • @Fortune IIRC Christoph said the Linwkitz Riley isn't ideal for modulating/tweaking. I've been using One-Pole for stuff like that, but you might have better luck with one of the other types.

    Have you checked the one pole style splitter in Plugin Dostor? I tried all ways but all of the filters in Hise is giving frequency bump (and phase issue) on crossover points.

    I guess the proper splitter can't be done in Hise for now 😞



  • @Fortune Yeh I assume it'll be tricky getting a perfect crossover with the ability to modulate it. You might have to implement your own for this 😨
