MAutoEqualizerLinearPhase High-Pass: Sharper Corners?

[TheAdventuringPanda]

I'm trying to set up a steep high-pass linear-phase filter with a sharp corner and minimal ripple.

I can get MAutoEqualizerLinearPhase to go steeper than FabFilter Pro-Q2 or Equilibrium, but I can't get MAutoEqualizerLinearPhase to give me as sharp a corner as the others. Here's Equilibrium (using an Elliptic filter) (left) and FabFilter (right):



Why can't I match this performance using MAutoEqualizerLinearPhase? If it's possible, please tell me how? If it's not possible, would you consider changing MAutoEqualizerLinearPhase to make it possible? I like your plugins a whole lot, but maybe I have discovered some room for improvement in this one?

Sorry, but this is unlikely to happen. Elliptic filters may be useful for scientific calculations, but they are not very suited for audio stuff. And check MAutoDynamicEq (or even the free MBandPass), these have up to 120db/oct LP/HP filters, which have no ripple at all.

I use MAutoDynamicEQ all day every day, so I understand it can do steep filters with sharp corners, but not linear-phase.

I'm working with samples which include low-frequency room-noise which was captured by the mics and recorded in the samples. I'm trying to eliminate the noise, without reducing the fundamental frequency of the instrument. I have seen people advise against steep filters for music-audio, and while I do avoid steep LP filters, I find steep HP filters work well for reducing room-noise, while leaving the instrument intact. So, I don't understand why you think elliptic filters aren't good for music-audio.

In any case, thanks for your response, and I still am finding your plugins very helpful.

First of all - elliptic filters are designed for scientific purposes - a steep response while surviving pretty crazy ripple and unnatural corners. Good enough for scientific stuff, but imho not good for audio.

There's a better way though - MMultiBandConvolution (yeah, I know you wouldn't guess that one, but convolution is a really strong tool ).

It can be easily steep like this (actually these are pretty much default settings) and still be linear phase, have no ripple at all etc. :

Thanks very much for this. That is extremely steep and sharp.

It can be less steep , or more
