Part one of a two-part tutorial on the difference between phasing and flanging modulation effects.
-
Hey guys, Eric Tarr for theproaudiofiles.com. This is a side by side comparison of two different modulation effects: the flanging and phaser effect. I get a lot of questions about these effects including the difference between flanging and phasing. Another is what are these processors actually doing to my input signal.
I’ve got a Pro Tools session set up where I’m gonna be synthesizing a signal to send through each plugin and then analyze what the plugin is doing.
I’ve got my signal generator plugin and I’m creating some white noise. I chose white noise because it has energy across the entire spectrum from low frequencies to high frequencies. I’ve printed the white noise onto a separate audio track, that way every time through, I’m gonna be passing the same exact signal through each of these plugins. I’m gonna be using the very basic effects, the stock plugins that come with Pro Tools: Air Flanger and Air Phaser. But you can do this demo with all kinds of modulation effects. Then after the signal goes through the plugins it’s gonna come over here and be analyzed inside of iZotope’s Ozone 5 meter bridge. What you’ll see here is the spectrum and then also the spectrogram to see how these frequencies are changed across time.
[white noise + iZotope Ozone 5 Meter Bridge]
I’m gonna focus on the flanger. I’ll bring it in, and you can see what happens all the way across the spectrum when I’m using the flanging effect. I’ve got it set up on the factory default. But for the sake of the demonstration I’m actually gonna change a few things so I can make it a very basic flanger. I’ll slow down the depth, slow down the rate. This will help you see what’s taking place. Bring down the pre-delay. I’ll bypass it, then bring it in.
[Air Flanger + iZotope Ozone 5 Meter Bridge Spectrogram]
What you can see happening is across the spectrum there are notches carved out. This is called comb filtering. You can see this in the spectrum and also the spectrogram how these notches are sweeping, they’re changing across time and they depend on things like the depth, rate and pre delay. If I change some of these parameters you can see what the effect is.
[flanging effect]
By changing pre-delay, what I’ve done is increased the number of notches and they show up at different places throughout the spectrum. I’ll lower it again. Now I can change the rate. What that’s gonna do is the sweeping of the position of those notches is going to happen at a quicker rate. Next is the depth. The depth parameter is gonna control how far across the whole frequency spectrum these notches are going to sweep. That basically covers the flanger. Another thing to point out is that these notches are occurring at harmonics of each other. At even and odd harmonics of where these notches - the lowest one is occurring - you have all these other notches taking place. That’s just a product of the signal processing.
Next let me move to the phaser effect. Like before I’ve got the factory default but I’ll change a few things so it’s a very simple phasing effect. Slow down the rate and depth.
[phasing modulation effect]
Right now we have a single notch being taken out rather than having a bunch of notches in the entire comb filter. The center of that notch is occurring around 1000 Hz, but it’s gonna sweep a bit based on the rate and the depth. So if I increase the depth you’ll see that the sweeping goes further and further across the spectrum.
[sweeping phaser]
I can change the rate and it’ll go faster. I can also change the number of poles. This will change the number of notches occurring across the spectrum, so I can go from having two poles, where you have essentially one notch to four poles. Now I have two notches. Six. Three. And then with eight you get four. One thing to point out is where the frequency notches occur, they don’t necessarily have to be harmonically related.
Last thing I’ll point out is with feedback you can actually increase the resonance of where the notches occur.
That basically covers the effect the flanger and the phaser have on an input signal. With the flanger you have this sweeping comb effect that starts at high frequencies and goes down and back up. With the phaser, you can center it around a specific frequency here and sweep around there. With the phaser you can also notch out one decrease in amplitude across the spectrum rather than having a bunch show up like what happens with the flanger effect.
In my next video I’ll show you behind the scenes what’s taking place with the signal processing that causes these comb filters and notches to occur in these different kinds of effects.

lmaoo xD
Lmao!!!!!!
That was actually very illuminating, good job.
Glad to hear it, Sonny! Thanks for your feedback.
this is the only tutorial across over 100 that ive looked at that actually helped me understand what the differences are tysm
blank. ???
ok
wise words.
I agree
gotta be one of the best videos of comparison between the 2 (flanger VS phaser). explained very clearly and very visually, great job man! (and this video is almost 8 years old!!!!) thank you!
I've been wondering about comb filters for years, this answers a lot of my questions :)
This work is great and I see what you are meaning very meaningful and all a unique way to share the difference
Hey man, thanks for the video, I appreciate your tutorial.
Thank you for an illuminating presentation.
Very nice video! Could you also do a take on the chorus effect as well?
this makes everything so clear
Brilliant visual demonstration!
Thanks for watching!
Thank you Eric Tarr!!
Really good video, good job
excellent video.
Flanger is a time-based effect, phasers are filter-based effect
@MomoTheBellyDancer Lexicon PCM80 has only time based effects. The phaser isn't included in that unit
@MomoTheBellyDancer That's because phasing is not a time based effect.
@MomoTheBellyDancer Same thing for the Rocktron Intellifex. It only has time based effects, and, once again, no phasing. Phasing is not a time based effect. It's a filter based effect related to wah wahs and envelope filters
@MomoTheBellyDancer Oh, come on. And I think the 2290, once again, has no phasing because it's not a delay (time) effect like chorus and flanging
@MomoTheBellyDancer What's the chances of all these time-based units leaving out phasing for no reason?
Great info...
thank you.very nicely explained
You are welcome. Thanks for your feedback.
Appreciate this great video. I Now Understand Phaser AND Flanger.
That's good to hear Lorenzo. Thanks for your feedback.
They're like an automated EQ who would have known.
u are my savior dude.. Thank u bro
Very clear
Brilliant! Just brilliant!
Thanks for watching!
this is amazing
THANKS !
Nice vid as always. Can anyone recommend an alternative for the Meter Bridge? I like the spectroman and spectrum analyzer in one
Can you do the same thing with distortion, overdrive and fuzz?
Very nice thank you :)
Thanks for your feedback, Patrick!
Do you have a vid that explains what chorus does?
@proaudiofiles
Is it possible to have a flanger effect that goes straight across on the spectrogram, rather than going up or down? Or would that be a different effect, and if so what would it be called?
I like the sound of a flanger, but I don't like the in-and-out 'doppler-esque' sound of it...
You can achieve similar effects with a very tight delay, or by playing 2 of the same records and speeding one up and slowing it back down slightly.
yeah and may sound interesting if you reverse polarity of one of records.
thanks sir
One of the best modulation explanations. I often felt the wah-wah effect should be in this catagory of modulation since it uses a sweeping filter, but it never is. Any idea why?
because technically a wah pedal is just simply a phaser where the depth / frequency is being controlled by a pedal ;].
Do you know if there's a certain name to describe what was happening when you were messing with the depth on the flanger? I've heard that kind of white noise down-shift kind of sound many times before, like in video games. I've always been curious about that...
+QuasarBooster Filtered white noise is very common, and on older games with the noise oscillator, the low quality audio could have been doing something strange. There isn't a name for it that I know of, but It's common in Electronic music. Some Classic rock used flangers on hi hats and dub and reggae both use similar effects too.
But where do I find the Air plunger plugin??? Why don't any of these videos answer that.
What plugin is that meter???? Is it abailable for vst?
Ur gonna wanna watch this at like 20% volume just warning ya
haha thank you
so, roughly speaking, I can automate EQ for flanging or phasing effect?
not exactly, a phaser is actually re-injecting some parts of the signal in itself, and creates the notches by phase cancellation.
phasing yes, flanger no
for me when processing the guitar the FLANGER works better, specially in the key of D
whats the name of the Spectrograph VST?
Izotope insight
You should look up "harmonic series". You could better explain the difference by referencing it.
whats The oppositie current of noise actually?
My guess is that it's analogous to light and optics: white noise is the presence of all (audible) frequencies of sound while anti-white noise is the lack thereof.
The only right answer is "silence"
reality
Wind blow
Who knows the DAW that he's using?
He says right at the beginning. ProTools

Man. Why ur Flanger/Phaser is TRIANGULAR?!?!? i hate that wave form because some thing I want to do with that wave form it glitches all the music. idk but I like The Flanger linear this form is cool to make eletronic beats. please make a vid saying how is that Type of Flange.
Some plugins have other shapes, like D16, or even stock FL plugins.
Triangular sounds good with fast speed/low depth btw.
It seems like a person could potentially make a phaser sound like a flanger, but can't really make a flanger sound like a phaser.
After watching this video i want some nachos
6:45 The Answer to the title, all the rest is demonstration.
the phaser offers more choices and can become a flanger.
How to make sound fx for nightmares 👍
Great explanation but no plugging can match real tape flanging/phasing imo
Im pretty weird but I have never liked Flanger.. Phasing tho
this plane doesn't even have a flange!
What a waste of time. Is this video for musicians or technology nerds ? Musicians want to hear how it sounds not how the wave forms look on a computer screen.
lol, that statement is unearthly stupid
then look up a guitar pedal video idiot
You sound like a dumbass more than anything
That is quite an absurd comment.
you can... watch other videos?
