Any Low Cut Filters that don't create peaks?

[electro]

Are there any EQplugins with steep low cut or high pass bands that don't create peaks?

[hoffy]

yeah heaps

yeah heaps

what good r u?

what do you mean by peaks? Q?

[Lunch Money]

Only a resonant low-cut will create peaks. Anything non-resonant (ie. standard EQ or any other non-resonant filter like Bugpass) will not create a peak.

I recommend bugpass as it's answer to all of those is "yes". Steap cutoff with no resonance, HP and LP.

Fact: very steep filters come with higher peaks.

Settle for a less steep filter and the peak will be lower also. A standard 24dB/octave highpass should be fine for most purposes. If you want to remove more bass, then simply set the frequency higher. It's always a compromise...

in many situations a high pass or notch cut causes peaks, mostly with smaller adjustments and on broadband material. i find there's a threshold where if you remove enough the peaks will start to reduce, but they are always inconsistant.

i find its not that simple, as it greatly depends on the source material.

I am trying to de-stress the following limiter plug by removing as much unnecesary frequencies as possible via EQ highpass. This means the filter has to be as steep as possible.

I'm no audio scientist, but I can't see how an attenuation of frequencies can cause a peak. Sorry for being skeptical, but I don't take it as a fact yet without evidence.

well try it then, take any mix (broadband sound) commercial or otherwise and attenuate any freq by a gradually increasing amount whilst watching your peak meter. i find the more compressed or full the material the bigger the peaks.

its a well known audio phenomenon in mastering particularly.

All filters create waveform peaks. Linear-phase filters create less amount of steep peaks since their step response is symmetrical. Filters with non-steep filter slope generally do not create considerable peaks.
