That "Barber Pole" Effect

I didn't realize how common this effect is...

 
Here's the Wikipedia link on the Shepard Tone if you're not familiar with this audio illusion.

Might be easier to just buy a barber pole.

Back in the what, late 70s, BBC Radio 4's original adaptation of "The Hitch-hiker's Guide To The Galaxy" used Shepard tones a lot as sound effects. Some of us spent ages trying to work out how they were created back in those pre-internet, pre-digital anything days.

A task at which we failed. Badly.

Interesting. I was already aware of the concept and the Pink Floyd example (i.e. the fadeout in Echoes). Thanks for reminding me about it. I am now intending to apply the idea to a sound effect that I have been working on, a rocket taking off and ascending.

I sometimes use con sordindo with a touch of harmonics to bring out the notes that are quite a valid note for effect. Takes away the boring synth string sound.

It's relatively straightforward to pull off, using the original Rapture synth.
And probably Rapture Pro, but less so in Dimension Pro.  Plus, you can save on string breakage.
 
  • Samples loaded into an Element.
  • Pitch EGs, StepGens, or LFOs ramping up (or down).
  • The corresponding AMP EG, Stepgen or LFO uses a triangle or sine waveform shape, for the overlapped mixing.
  • Copy Element 1 to Elements 2, 3, and 4.
  • Offset each Element's Pitch Modulator shape by 90 degrees [0 - 90 - 180 - 270] in successive Elements.
  • Offset by the same amounts in the corresponding AMP modulator.
 
Instant quadrature "LFOs", and a one-note wonder preset that'll amaze and alienate your friends  You can do the same with simple oscillator sources, endless filter sweeps, quantized microtonal scales, clangorous bell tones, etc.

Anyone into MeldaProduction plug-ins should watch the following video tutorial.  It's 18 minutes long, but well worth the time spent.  What you are shown is quite amazing: an implementation of a barber pole effect using stock Melda modulators which are present in most of the Melda FX line.

Or, you could position four photoresistors perpendicular to the four quadrants of an actual barber pole, configure them in a voltage divider circuit that then modulated four oscillators' frequencies. 
 
On second thought, that would be impractical. No place to plug in your four Minimoogs out on the sidewalk in front of the barbershop.
 
OK, I got it. Employ a barbershop quartet who can sight-read, and position them around the barber pole! Sometimes the simplest solution is the most elegant.

I saw Dunkirk last night, and was loving the soundtrack (along with the rest of the film).
interesting to see this clip all over the internet today.  I hadn't heard of this technique before, but it was really, really effective in such drawn-out tension.

There is probably an easy way to achieve this with some of the string libraries available. Not that I plan to use this effect anytime soon, however I might try to create this effect for edumacational reasons. 
 
Going to try something and upload it to cloudsound.

It should be pretty easy to do, if all you want to do is demonstrate the principle.
 
I'd use a synthesizer rather than a sample library, because I could then turn on portamento/glissando for a smooth rise in pitch. I'm not sure that's even necessary, but it would more closely emulate the familiar THX "Deep Note" motif that we've heard so often at the start of movies. BTW, that little piece uses 80 voices (!).

I like to mimic not imitate. I'm pretty sure you could automate portamento in play then add tweaks using melodyne or something. I think I have 1 piece in my mind it would be suitable for.

Another example would be the orchestra part in the Beatles "A Day in the Life".
It gives the illusion of a continually rising pitch until reaching the final note.
 
 
https://en.wikipedia.org/..._in_the_Life#Orchestra
 
        "Martin later described explaining his score to the puzzled orchestra:
What I did there was to write ... the lowest possible note for each of the instruments in the orchestra. At the end of the twenty-four bars, I wrote the highest note ... near a chord of E major. Then I put a squiggly line right through the twenty-four bars, with reference points to tell them roughly what note they should have reached during each bar ... Of course, they all looked at me as though I were completely mad."

Cool.
 
I'd be interested in learning about other audio "illusions" like this.
 
Just some names of the techniques and I can googly-fu it from there (but links would of course be welcome). I very much like this sort of thing.
 
Cheeeers!

Also read up on Diana Deutsch, the psychologist who discovered and/or documented many audio illusions. She created two CDs called Musical Illusions and Paradoxes and Phantom Words and Other Curiosities to demonstrate them. Both are available on Amazon.
 
Here's a free PDF written by Dr. Deutsch that goes into the Shepard illusion.

Re: That "Barber Pole" Effect 2017/08/01 12:05:22 (permalink)
This was very interesting.  So I made a quick SONAR project to do this with a string library but I wasn't happy with the results.  So in googling I found this page:
https://jordaneldredge.com/blog/endlessly-rising-shepard-tone/
 
With a MIDI file already setup.  I thought, "Great!  That will save me some time".  Then I found that SONAR wouldn't load it.  I could play it with AIMP3 and I could load it into Reaper.  But what I didn't notice is that one of the tracks actually has MIDI notes above G10 (or G8 if you use -2 for the MIDI note name offset).  Reaper still loads the file and shows (??) for those notes, but SONAR just refuses and offers no insight into why.
 
Here's a cleaned up and SONAR friendly version of the MIDI file.
https://drive.google.com/...vzx_2Pac0R3c2M0anJqNXc
 
Odd how SONAR forces a Matrix track on it when saving as MIDI though.
