Linear Phase Eq

[kdgh]

Probably more people asked this question but i still don't get it.

What does, solve, avoid a linear phase eq ?
and why use it in a mastering job etc.?

Already thanks for all the help!

Cheerios,

the answer is in the question

Cheerios,

Without wishing to be obscure, it does the thing you ask it to do (eqing), without doing extra things (like messing with the phase). This isn't always desirable as sometimes the extras sound good. Tends to be useful in mastering when you want something really clean sounding to make a subtle, specific changes without having any knock-on effects on other frequencies.

Linear Phase on tracks?

Kindly recommend a good linear phase eq

Linear phase eq during mixing

another take on "digital eq's are all the same"

linear group delay EQing

When do you use a Linear Phase EQ over a Minimum Phase EQ?

do linear phase EQs matter if you're only cutting one band?

Linear-phase EQ is mostly a red herring, beloved of people who don't understand phase. For a start, the audibility of phase is low (certainly not zero, as has been proved a few times, but low). Very often EQ is actually trying to reverse a physical effect which probably wasn't linear-phase in the first place - far more likely for it to have been minimum-phase, which is completely different.

So in practice the difference between linear phase and any other kind of EQ is likely to be very small, if the amplitude response is identical. Since, however, it's actually quite hard to make two filters with identical amplitude response, most people who think they have compared linear phase EQ with non-linear have actually really been comparing two slightly different amplitude responses.

Yes, it's a point that is often missed: Problems in audio are almost always minimum phase and can only be corrected by minimum phase solutions.

Also, while the audibility of phase (especially at HF) is somewhat controversial, the audibility LF pre-ringing is not.

All I know is that I use linear phase less and less.

Just about the only thing for it these days is tight notches. Sometimes I get stuff that has a sharp ~2kHz resonance coming from the guitars, and LP seems to mess less with the rest at high Q's.

thanks for helping me out on this one. I still don't fully understand it, but i think the things are getting clearer
