Masterers, what is your opinion/use of linear phase EQ? Equalisers (HW)

Masterers, what is your opinion/use of linear phase EQ?

Mastering engineers, what is your opinion of linear phase EQ?
Also, what uses do you have for linear phase EQ?
Do you prefer it over other EQ?

Please explain.
Thanks in advance.

I used to use it for low end filtering. These days I prefer to use a good minimum phase EQ because it sounds more natural to my ears. Linear phase processing can often sound a bit smeary &/or slightly softer on transients. It may suit some things but I rarely use it any more.

The Algorithmix Red sounds best if you need LP processing.

I agree, I've used a couple including algorithmix, which is quite good, but I find most good minimal phase EQ's do the job equally well if not slightly better sounding. It might be less damaging for something extreme, but then again if it needs such an extreme correction, it's probably not so high def that the difference between a linear, and minimal phase will be audibly preferable.

I actually tried to do some research on the perceived differences back in grad school, but it turned out that we couldn't match the Q's close enough to get a valid result with preference testing, at best we could say they both sounded good.

I like to use linear phase Eq on the upper frequency range only, like above 2K and higher. i don't like to use them on the lower mid to lower frequency ranges.

My experience is similar to Matt's.

Used to use it for a lot of things a long time ago, cut back to just using it for low-cut filters, and now don't really use it any more.

Well I think linear phase eq is not so usefully anymore because it does not sound like a normal eq does. So it will make a track more sterile only.

Thanks for answering guys...

I'm surprised by these answers but educating myself is what it's all about.
I feel like a devil for asking though... check this out:

Was using PSP Neon HR in LP for a while, then I realised that it made everything sound wierd, some people say smeary, or plasticy.. all I know is that I loaded up some sessions and did some A-Bing and found subtle, yet annoying, digital distortions going on which just never sounded nice.

Here for the gear
 

I have tried the Waves mastering EQ long ago and the PSP Neon recently.
None of them convinced me to use a Linear phase EQ.
If you find the right frequency and the right Q, a classical eq is great.

We have the Weiss EQ1-LP, and used the LP mode often in the beginning, but as good as it sounds there, we use it almost exclusively in regular mode.

So like Matt, Alan and others mentioned, we use it less and less.

Cheers,
Thor

No LP EQ here either.

With Sontec, Millenia, Z-Sys, and even Flux within arms reach,

Why bother with LP.

Best, JT

No, never.

And the lower in frequency you go with LP, the worse it is.

Where did the idea come from that LP is "mastering grade," anyway?

Good question.

If we knew who made the first commercially-released (and marketed) LPEQ then we might have a clue. However, my off-the-cuff guess would be Waves.

They bundled the LPEQ and LPMBC with the L2 and called it the "Masters" bundle. According to the manual (link below) they released this bundle back in 2001 and it states...

It is primarily intended for use in Mastering though it is very possible to use for other audio processing needs as far as your process power will allow.

On the topic of linear phase plugins.. What do you guys think of linear phase multiband compression as in the waves Lin MB?

I use Alg. Red some for orchestral but for regular pop only the long slopes and that only very very occasionally. I also never use it without first comparing what regular eq. sounds like to make sure it's really better overall.

It's always important to listen for what signal processing is screwing up in addition to what it's helping.

anyone tried fab filter proQ in lp mode? a friend of mine uses it all the time in this mode (mostly over 2khz though), he does the actual settings in minimum phase mode and switches to the lp mode (with highest latency setting) when he´s rendering...he says it sounds more neutral and transparent in this mode...I´m thinking of getting the fab filter pro Q because when I saw it, I really liked the versatility and usabilty (awsome gui)....what are the opinions about it´s sound and especially how it sound in lp mode (with highest latency)?

Love the Pro-Q.

Almost never use it in LP-mode, though.

I use linear phase (red) for surgery and extreme boost / cuts. I use minimum phase for color and character.

There are (for me) a few interesting and unexpected answers in this thread

I use Linear Phase EQ when doing parallel processing for electronic music: for this application, only Linear Phase EQ allows to keep the phase artifacts to a minimum when summing the parallel signal with the main one. For acoustic instruments, I would avoid doing that, as it can create strange timbric effects... But with electronic music, the positive effects in bringing up loudness and detail without squashing the dynamic almost always cancel the negative effect on timbre (if any can be peceived at all).

OT but on your site it says Vintange Warmer by the way.

Linear phase EQ. causes unnatural pre-echo artifacts. You need to judge if their effect on transients or the phase issues are the bigger problem.

I think monitoring is a lots bigger deal with digital signal processing than it is with analog. There are lots more wrong choices to make.

yes, it does...and?? It also says i'm running weiss eq1-mkii. I haven't used the vintage warmer in years. Most my coloring is done with the mini massive, great river maq-2nv, algorithmix blue, tube-tech smc2b, eq1…Red for surgery. Lots of flavors, lots of options. I broke up the massive passive a couple years ago. I guess i need to update my site.

My opinion, need for it and use of it are all very little. And as has been mentioned elsewhere, use of EQ in general tends not to be for addressing linear phase issues.

we did some blind testing today at my friends studio with the fab filter pro Q in lp mode (maximum latency setting) and in minimum phase mode (zero latency)...the absolute clear result was: it sounded way better in lp mode, the only exeption was one setting where we used the ms mode and aplied a shelfing filter + a low cut on the side frequencies, there clearly the minimum phase mode won....I don´t know other lp EQs but for the fab filter pro Q at least, the lp mode is so much better, in most EQ situations...way more transparent...no colour at all, but who needs that if there are so many other options to get colour in your mix......
I will def. get that plug in...best software EQ I ever heard!!
