i just saw this and now i cant keep it out of my mind..

what did u think?
always linear eq to mix?

 

1. Analogue phase EQ do not produce phase shifts by boosting or cutting a freq, it's the other way around. The phase shift of a freq produces a boost or cut, it's a side effect, so to speak.
2. Therefore these phase shifts are completely normal for analogue hardware EQs and digital EQs with analogue phase.
3. There are (really expensive) analogue hardware mastering EQs with a range of +/- 24dB!
4. Linear phase EQs come with some latency and produce pre-ringing which is pretty bad for a critical attack phase because they smear it.
5. The higher the input into a non-linear plugin the more harmonics are produced (quantity and level) and the higher the risk of aliasing. That's nothing new.

 

I only use FIR filters. I do not see any reason not to use FIR anymore.
The moment you hear the effects of pre ringing you probably use too narrow or steep filters with to much gain anyways.

And I never use big boosts or cuts with narrow filtering in the bass at all.
The FIR filters we have today are extremely well made.
I never had any problems with pre ringing.

 

Linear EQ on mastering only. Save yourself the hassle and the headache of asking yourself why your drum transients are booming in weird spots, and only use Linear EQ on mastering chain.

 

It feels great when you have nothing more to add to what everybody's said already.

 

Nice! thanks to ALL for the responses ! ♥

 

The better, clearer and punchier a mix is, the pre-ringing of linear phase master eq is immediately apparent. Even at small eq action. That “silk” the untrained ear hears is actually preringing under desguise. And as soon as we play the LP mix immediately after or before a well done mix in a similar genre, we realize ho much the LP softens everything.

LP on the master is pretty much a benchmark: if you use a linear-phase eq on the master and notice no issues, then the mix has already bigger issues and the preringing is a secondary issue.

Unless is really really really necessary to use a LP eq (some restauration work for example) (and preferably a second set of ears also confirms the decision), I’d stay away from it.

 

I use IIR EQ on the master, and a mix of IIR & FIR (linear) EQ on tracks, depending on whether pre-mastered content might clash.

 

hi, i dont know what means "LP" in your words...

LP on master: wow didnt know about that...im gonna review one song that maybe this is the case ! thanks. but i dont know what LP it is, pls explain to me.

 

do u refer to like the Ozone 9 options? there u have IR IV etc? u use IIR ? sorry i dont understand

 

I always appreciate the knowledge drops.

 

Use LP EQ for multiple mic recording but don't always use them. Especially for drums recordings, most of the time minimum phase (the analogue phase) should work fine but if you are doing drastic EQ moves sometimes flipping the phase of the track or using Linear phase EQ can give better result, always check for that if you are losing a lot of details when playing the tracks together, that assuming you don't solo EQ a track. Phase relationship only matters when elements with similar content played together in context. Other than that you shouldn't worry much about phase change because of EQ-ing, it's just only natural EQ will somehow change the phase.

Steep High Pass filter (48db/octave above or even brickwall) can also introduced some drastic phase change and sometimes up to 180degree (depends on the source) that can produce an audible effect that can sometimes be useful for Kick drum and 808 bass for some umph. People won grammy with that trick. Phase changes are not that bad really, being aware of the potential phase change is a must, using Linear Phase EQ on every track is not. Try the Kiloheartz Disperser if you want to manipulate the phase-shift if the EQ-ing causes too much phase changes especially on the low end. It can sometimes produce better result than Linear Phase EQ.

Haven't seen it this way.

 

Sorry, thought it was another video from him

Not quite, even 12dB cuts produce a complete phase twist but it's pretty far away from the cutoff frequency.

This, OTOH, is absolutely correct and widely underestimated.

 

LP is short for Linear Phase EQ (but only when is the subject of the discussion). Otherwise, most of the time is Long Play vinyl

 

In context of audio engineering, it's always Low Pass to me, especially with EQs.
