This video made me so happy, I came here looking for bronce and found gold. I've been looking for the phase cancellation stuff for so long and this video puts it really clear and easy and shows you how to fix it!!!!
Awesome demo; I loved how you showed what was happening with the meter. The Linear EQ is actually a “linear phase” EQ (if I remember correctly), meaning it doesn’t rotate the phase like the channel EQ does. Hence the name “linear”. Thanks for the great explanation!
This is why I'm here. I heard the sound changing in a way I didn't like, switched to the Linear and the strangeness wasn't there. I figured someone must have covered the WHY on YT. Thanks for highlighting this. This video would have a lot more views if it was titled Careful With Channel EQ: Isn't always doing what you think. 🇹🇹
Thanks for this video. I was looking for a video regarding eq on every channel or on a bus. Your video gave me some really valuable information that I didn't even know I needed.
That was really fascinating! Thanks for the great tutorial on the differences between the two. Blew my mind that the channel EQ high apss filter can put something out of phase.
Absolutely helpful! It has been a challenge to get my Vsti's (stereo instruments) to be in phase and not disappear in a dense mix. I think trying this will certainly help to bring out the full sound of each track. Very useful brother!
It's true, the difference isn't just for live tracked instruments! I've found Drum Kit Designer can benefit from using the Linear EQ's high pass filters when EQing the individual drum sounds.
Help me clear up a question, please. The phase rotation-is that only a problem if you have mic bleed? And does this mean there are no phase issues when hi-passing other channels? It seems this should be the case, but I wonder. I assume the problem with bleed that's phase rotated is the destructive interference cancellation caused by that, but I'm not sure I'm right about that. If I am right, channels without bleed should likely not be affected by the phase rotation. For instance, I hi-pass everything (a channel EQ on nearly every track) to keep the mud from building up. If I check the correlation meter at the output, it's fine. If I have 70 tracks that are all individual and are all software instruments, as an example, meaning none of them have bleed, it's still fine. But I am tempted to do an experiment where I replace all ch EQ's with linear EQ's just to see what happens. I'm told an M1 MBP even with 8 GB RAM and 512 GB SSD can easily run 100 tracks with lots of plugins, but I wonder what would happen if I put linear EQ's everywhere, whether it would sound better, and whether it would choke.
Thanks for suggesting! My best advice is to check out the Acon Digital Restoration Suite. Great De-Clicker in that bundle, and much cheaper than other options (such as iZotope). The only way to deal with pops and clicks in Logic is to go into the File Editor and use the pencil tool to redraw the wav form. I'll definitely add it to the list!
i knew it, i knew it it sounds better, when i pull something down at 500, the audio sounds like a cheap walkie talkie toy, when i do it with the linear one, it just sounds reduced, uh thank God im not crazy.
I notice that I get that phase issue sometimes even when high passing 808's at around 30 hz. I know hip hop production with samples aren't multi-mic'd, but do other's have that problem?
if your samples are perfectly attatched to the grid and always fired at the same time (for example kick and snare, or kick and clap) there will be some overlapping frequency content, hence there will be some amount of correlation as well. or maybe your 808 kick is in or out of phase with your bass synth, that can happen as well. in that case you can try some sidechain compression on your bass synth from the kick as another option. edit: if you use other kick samples, they can also cancel out with your 808.
There sure can be! The effects of pre-ringing tend to be more exaggerated with boosts than cuts. A great article all about pre-ringing: cravedsp.com/blog/linear-phase-eq-explained
3:45 Woah woah woah, how did you get each different mic on its own track? When I record, it just records together in one track.. Might be a dumb question, but hey, I a little new at this..
You have to set up all the track with all a different input (for the different mics) and then you just click the R button (or the red circle in some cases) on all the tracks. When you'll record then it should be like he's doing there (: I hope this helped.
Absolutely! High pass filters tend to rotate phase. Of course, the steeper the curve, the more it rotates. And the gentler the curve, the less rotation. Linear EQs are great for high passing when you don't want to have to fuss with flipping polarity/phase constantly.
Phasing is very minimal in most cases. There's no need to go around like a detective trying to head it off. Just target any situation where mics may be more than two. And if you have done your own miking then you should already be ahead of the game.

Linear eq is not best for mastering. No analogue eq is linear phase and people use analogue eqs for mastering all the time. It's not higher quality, it causes pre ringing artefacts that can be audible in sections with just percussion. The reason it uses a lot more cpu is not because of higher quality but because it uses finite response filters which require more compution. There is nothing inherently more high quality about them. If you look at mastering eqs (say plugin eqs designed for mastering) you will find that none (or almost none) of them are linear phase. The case you described with the snare is when you would use a linear phase eq. Not when mastering.
your explanation at the beginning is flat out wrong. to anyone who cares: please watch the fabfilter related video on phase and what the difference between a usual eq and a linear phase eq is. i will still try to explain: linear phase has nothing to do with the quality of the equalizer. and using linear phase eq on transient rich signals is actually the worst idea of all, especially when using steep cutoffs. all equalizers produce a phenomenon called ringing, it is the filter resonating with itself. and a resonance can be seen as a sort of frequency reverberation. the the steeper the filter, the more ringing you get, and the longer the resonance trail gets. in linear phase eq's, there is additionally something called preringing. to get rid of the phase shifts, the filter is also applied to the time reversed audio signal. this is also the reason why it takes more cpu usage and induces latency. when the signal gets reversed to be normal again, the resonance, or ringing, starts before the actual signal starts, hence preringing. again, you can imagine it like some kind of short frequency specific reverse reverb put on your signal. you don't use linear phase eq in mixing because you don't want the transient smearing that happens because of this preringing effect. the most useful application is in parallel processing of tracks, but even then you at least need to be aware of the preringing it can cause. so if not absolutely necessary, don't use steep filters with linear phase. in case of drums and other correlated signals, you can take the phase shifts caused by the usual channel eq to your advantage. in most cases, the signals are not entirely out of phase nor entirely in phase, but somewhere in between. by tuning the steepness and the cutoff frequency you can get the fundamentals of the drums even more in phase with one another, while with a linear phase eq the offset will just stay the same, and your only option is to flip the polarity.
When you work on a dense, longer composition that has many different instruments rather then a song, then surely you may need more tracks unless you are gonna be connecting/gluing pieces out of different sessions. I doubt many people do, but surely there are some hidden gems who have the balls doing so.

Man, I never thought channel eq can cause phase shifting... you earned a new subscriber bro
Great tutorial, have you tried highpassing with Midside on the regular EQ? It seems to fix phasing issues without destroying the quality.

great video and great teaching!
Great demonstration! I always learn so much on this channel.
i'm struggling with the low cut problem for days and saw this video, thx a lot
Wild, never would have guessed there was a difference. I thought the channel eq just added the linear eq plugin to the chain
absolutely amazing information. EVERY Logic user who does mixing with multi mic'd instruments (like drums) should watch this! Thank you!

yesss. Finally i find exactly what im looking for! Great Job man!
Could you do a video on getting pops, clicks and stubborn anomalies out of audio tracks? That would be tremendously helpful!!! Love your videos!!!

Thank you. I will check it out and I look forward to it. There are not any in-depth videos that I have found on the subject.
great stuff bro
is there the same hipass phase problem with the auto filter or the single channel eq?
i knew it, i knew it it sounds better, when i pull something down at 500, the audio sounds like a cheap walkie talkie toy, when i do it with the linear one, it just sounds reduced, uh thank God im not crazy.
I always stick the channel eq on the stereo out track, mostly with no curve at all. Widens the mix, adds clarity, it sits better, etc etc etc
What??? I don't hear any difference
@@JuanJacinto sorry, should be linear eq
I notice that I get that phase issue sometimes even when high passing 808's at around 30 hz. I know hip hop production with samples aren't multi-mic'd, but do other's have that problem?

edit: if you use other kick samples, they can also cancel out with your 808.
Great and helpful content!👌Thanks man.
Okay I will implement this for sure
Amazing explanation. True Knowledge ❤
Isn't there preringing when using Linear EQ (which is more noticeable when high or low passing) as opposed to standard EQ'ing???
There sure can be! The effects of pre-ringing tend to be more exaggerated with boosts than cuts. A great article all about pre-ringing: cravedsp.com/blog/linear-phase-eq-explained

Very useful. Thank YOu.
Excellent tip man. Do you find this anomaly happening with 3rd party EQs (Fabfilter, Ren EQ) as well or is it just with Logic's EQ?
Absolutely! High pass filters tend to rotate phase. Of course, the steeper the curve, the more it rotates. And the gentler the curve, the less rotation. Linear EQs are great for high passing when you don't want to have to fuss with flipping polarity/phase constantly.
@@WhyLogicProRules Very Cool. Thx for explaining that. I have been recording and mixing for over 25 years and was not aware of this issue. 👍🏻
Seriously great tip! Thank you!
This is why Why Logic Pro Rules rules.
Wow! Learned something today! Thanks!
You bet :)

Don’t know if this adds much but the channel eq is essentially a minimum phase eq to begin with
Great info thanks
brilliant
Thanks 👍🏻
cool vid my man!
Thanks Todd!

PS this is everything I hate about modern attitudes to recording and mixing.
who on earth needs 100 tracks ? Answer that question first.
When you work on a dense, longer composition that has many different instruments rather then a song, then surely you may need more tracks unless you are gonna be connecting/gluing pieces out of different sessions. I doubt many people do, but surely there are some hidden gems who have the balls doing so.
