Barberpole phaser / infinite riser fx auv3? Drambo patch? Izotope mobius jet engine filter iOS
Hello!
I posted this almost 2 years ago but am wondering if there is anything new out there better suited
I am looking to find an auv3 solution capable of creating the infinite riser effect that izotope mobius filter brings to live input where it makes incoming audio sound like it is tethered to an infinitely rising jet engine
My understanding is that mobius filter is a particularly elegant implementation of a barber pole phaser or at least largely based on the same concept
I have used QuatroMod for this previously but it doesn’t seem to produce the same ever-ascending swirling depth
Can anyone recommend any auv3s particularly well suited for creating this sound?
Has anyone made a drambo or nurack patch that does this?
I am working on iphone if that is relevant

may do what you want. for clarification you could ask the developer if he has utilised all pass filters with his frequency shifter ( like Harald Bode did with his barberpole phaser ).
moebius lab may also allow for barberpole phasing with their frequency shifter. contact them and ask. ipad only.

this is a very good question.
I haven't found anything that does a proper barber pole. I imagine this could be built using drambo (being that you can have as many modulated filters as your heart desires and route any audio through them), but have no idea where to start.
@annahahn, @frond, @palms
Coffee lasted long enough for another Lego session. Use inside the Drambo AUv3 audio effect plugin.

I didn't know I was missing this, but now that I hear the effect, I recognize it. Nice patch, @rs2000! I'm planning to dive into your drambography once I have some free time.
I wonder if @FredAntonCorvest might be interested in adding this barbershop pole effect to FAC Phazer.
Thanks a lot, great stuff as usual. Can it be used to create shepard tones ?
You're welcome!
No, you'd have to use multiple oscillators (each pitched one octave apart to the next one) to achieve that, plus a lowpass and highpass filter to let the voices fade in and out of the audible frequency window smooth enough to be unnoticeable and to suppress voices jumping from highest to lowest pitch.
I'll be releasing a Mozaic script for that at some point. Here's an example, but it's with 8 oscillators spaced slightly more than an octave apart. A true Shepard Tone would use 9, and it would be less dissonant. I used 8 instances of Tera Synth for this, because it's low on CPU, and allows pitch bend from -48 to +48. @rs2000 I think you can just automate the volume, instead of using filters. You can do a ramp up on the pitch, a triangle on the volume, and start the LFOs at different "phase" points.
@rs2000 @Skyblazer
Thanks guys, it seems that we are not there yet but I guess the possibility exists and I hope that we will see this one day in our AU arsenal ! It is a fantastic effect anyway
This is completely brilliant thank you so much @rs2000 🙌🙌🙌🙌🙌🙌🙌
Experimenting with it now, you said this is not an ideal incarnation? What do you see being problematic about it?
Also what are the relevant parameters to change to effect rate-if-rise etc? I am a bit confused about the interplay of the 3 LFOs and which ones to adjust, which ones should remain in sync etc- any insights or tips would be infinitely appreciated
@rs2000 - one other thing I wanted to ask about this implementation, is there some sort of frequency bias or range that works better than others? When using it on higher/mid frequencies it sounds fantastic but when I put it on a track with a basic 4xfloor house beat the kick drum comes out crazy distorted even if I limit it before, I can’t seem to get it to sound decent on bass- do you have any tips for getting it to sound clean on bass frequencies?
Again thank you so so so much for taking the time to create this is have been searching for a way to achieve this on iOS for so long
Thank you! 😊
If you like the sound then nothing! 😊
"Ideal" to me would be an even smoother sound but that would require a lot more modules and I opted for a compromise with acceptable CPU load.
Good point. I will add a few knobs to make these changes easier.
Can you send or link to an example audio file?
Source material with much bass and little treble/midrange will naturally not profit much from the effect but I can have a listen nonetheless.
Cool! 👍🏼

Here is a heavily updated version:
https://patchstorage.com/barberpole-phaser/
V1.1 with quite a number of improvements:
Even better, thanks so much!
Hi @rs2000
Thank you so so much for updating this!
Going to take it for a test drive now
I created a bounce of the a/b between the raw drum loop and the barberpole version from your version 1.0 of the effect
Let me know if there is anything specific you’d like me to try with the latest update or anything else I can send your way
@rs2000
Did some more tests with version 1.1 - sooooopa nice to use thank you so so much again for creating and updating this- truly a joy to use😆
I did some more tests with the drum loop- I’m able to get better results for sure just by fiddling with the compressor which fixes the distortion of the bass- but it has a way of leaving the signal quite thin sounding- I can then slap an EQ on after drambo and beef up the sound a bit but it seems like you say low frequencies are not particularly well suited for this sort of processing? Is that because of there only being 5 filters in the sequence? Also, I think this is wise to keep the number of filters small for CPU reasons like you said, I imagine drambo is not ultra cpu efficient as a trade off to its flexibility, but i did already notice even a single drambo instance running barberpole v1 uses a decent amount of CPU (according to the wonky meter in Cubasis for whatever that’s worth- I did some tests with a single instance where it jumped 20%, but then duplicated the track 5 times and it seemed like the cumulative instances only resulted in a 30-40% increase in total, meaning the cpu load of 5 instances was only 10-20% higher than with a single instance)
I’m attaching some videos i recorded of my tests here

Regarding the frequency knobs- is the idea that for low sounds- set low, high sounds-set high? Should all frequencies be set to the same number to give a smooth transition?
@annahahn You were right, the bass was really out of control.
Thanks for posting the examples, especially the WAV file!
Now updated to V1.2 with tamed yet still punchy bass.
Should sound much better now. Apart from the bass, nothing was changed.
https://patchstorage.com/barberpole-phaser/
And indeed, Drambo is very cpu efficient.
The idea of the frequency knobs is to let your ears be the judge.
Don't even think of what they do technically, just turn them until you like the sound best.
They are to change the overall sound character and to avoid nasty resonances coming from your audio material that might already contain resonant peaks. These knobs help to avoid boosting them even more while keeping the phaser effective.
@rs2000 my G-d this sounds gorgeous- I’ve been trying to find a way to get this sound in iOS and now that it’s here it’s so so so so fun I’ve been playing with it all day and now hearing it sound this clean on bass is so awesome
Wanted to ask you one question- in mobius filter from izotope, you have basically captured the essence of this VST’s sound/parameter set minus one thing, there is an xy pad with a Y variable for what seems to be the ‘center’ point of the rising frequency....I’m not exactly sure what is going on technically but if I had to guess... it sounds like that’s either the beginning or median frequency of the filters the sound is being passed through? The effect of changing this ‘center frequency’ in mobius filter chances the dominant resonant frequency of the sound...so it basically sounds like adjusting the size of the neck of a wine bottle in real-time while a tire hose is blowing air into it cocked to the side so it can whistle back out - high values the neck tightens and the center frequency ascends. Low values center frequency descends~ is it possible to address a set of parameters that would shift this central resonant frequency/ control how resonant the filters are? For instance could there be a knob that addressed the central frequency and another that addressed the resonance across all the filters? Or is that made possible through some different architecture unique to mobius filter that sets it apart from a traditional barber pole?
also super nice having those 5 independent sweet spot frequency knobs, I love that addition super nice to be able to sculpt like that I get crazy nice resonances that breath really nice life into things that I haven’t experienced since using physical modeling modal stuff on desktop
Wow @annahahn, thank you for your lovely praise.
I didn't expect that at all, after basically throwing together something that I roughly remember from my studies 20 years ago 😅
Thanks for the hint, now I had to check mobius filter of course.
I'm very surprised that iZotope didn't care much about avoiding that obvious "rising restart" effect that I wanted to avoid by all means in the first place.
Even more motivation to build something better.
That will take a while though. I'm sure that there will rather be a completely new Drambo project after digging more into that matter...
@rs2000 apologies for my wording, I did not intend to describe some potentially complex schema and ask you to implement it.
I’m more wondering if within the current patch architecture, is there a variable/parameter that I could attach a knob to that would allow me to control the center frequency of the barberpole?
Hi there @Skyblazer, did you ever finish your Mozaic script?
I'll release one later today. I've been exploring a bunch of ways to add flavor to the effect, like having the voices start and stop when they pass 0, but it's becoming abstract and inaccessible for something that already requires 5 minutes of loading and connecting things, so I'll save that for a second script. My further exploration is inspired by the THX sound test; that was created with a DAW, so the voices can swell in volume, switch places, and stuff like that. So I'm (slooowly) creating something like an "instrument" for improvising and performing that type of sound.
But here's a Drambo version for now!
https://patchstorage.com/shep-riss-gliss-for-drambo/
Brilliant thank you!
You're welcome. Here's the Mozaic version:
https://patchstorage.com/shep-riss-gliss-for-mozaic/
I've included some instructions on the PatchStorage page, and within the script itself.
If anyone wants the AUM project where I have it hooked up to VirSyn's MicroTera, you can PM me.
It outputs pitch bend and CC#7 on channels 1 through 8.
So you want each track's volume slider to listen for CC 7, on the channel corresponding to its voice number.
And then you set each synth to receive MIDI on its corresponding channel.
If you're using a synth that is hard-coded to respond to CC#7, and you want to use your DAW's volume sliders, you can change the CC# from 7, at the top of the code.
Not hard to set up, takes a few minutes though.
OMG, I've seen your post 11 months late 😄
But I'll see what I can do.
Better late than never, right?
I downloaded the Shep Riss Gliss Mozaic script today from PatchStorage.
https://patchstorage.com/shep-riss-gliss-for-mozaic/
I tried a bunch of synths but can't get it to work. I've reluctantly concluded its a 'me' thing.
As Synthmaster One is a pretty common synth, or Moog Model D, can someone (perhaps @skyblazer) please post idiot proof step by step instructions of how to set up the Mozaic params, Aum, and the synth?
I know I'm setting pitchbend in the synth correctly (to +-24) and the synth is receiving on the right channel, but all it does for me is output constant tones :-(
Yes, I'll write some better instructions tonight. I'll also upload a new version of the script. It's not working for me now, either! Strange, because unlike some of my earlier scripts, I tested this one pretty thoroughly. Thank you for reporting this! Hopefully I'll have it working by tonight or tomorrow.
Thanks so much for the quick response, looking forward to it :-)
