Cetera or cetara is a plucked string instrument played in Corsica. It has sixteen, or sometimes eighteen, metal strings, running in paired courses, with a body similar to the mandolin, but larger, and is plucked with a plectrum made of horn or tortoiseshell.

After revisiting that old classic, the Cetera Virtual Barbershop, I was trying to figure out why it still works so well today versus more modern recordings. Is it the quality of the sound?
Cetera's special algorithm? Maybe, but one thing I think goes unnoticed and vastly underutilized is that the recording creates a much larger sense of space before whispering in your ear or getting things close. Manuel plays his guitar in the corner, Luigi walks around the room, he washes his hands, It gives you a chance to mentally map out where things are coming from and makes the instances where stuff is actually close to your head really pop. How I see it is that a lot of ASMRtists simply buy a 'binaural microphone' and expect it to do all the magic. Unfortunately the effect will be quite weak. Professional binaural recordings are done with precise alignment of normal stereo microphones and specifically tuned software processing to get the psychoacoustic sound modeling right.It is easy to agree with you that the classic barbershop video remains unrivaled. An ASMRtist that could reach the same level of quality (in terms of an accurate 3D sound image) would probably become very popular.
I think that's definitely part of it, but as I understand it, a lot of the Cetera Barbershop was done in post. I'm not even sure it was true binaural at all.Also have to keep in mind that a lot of ASMRtists with binaural equipment don't actually do a whole lot in order to give the sense of dimension. Most people who own something like the 3Dio Freespace put it on a table, and then whisper or move objects directly to the left or right ear. They don't place the mics on a stand and then walk around them, or walk away and walk closer, or move objects above or below the ears, or do anything that would give the listener a sense of dimension and sound space.I've listened to a number of binaural recordings made with simple in-ear binaural mics, where the recorder would do something like walk through a park full of people on a winter day, and the sense of space and dimension was amazing.
It's just that most ASMRtists aren't into recording stuff like that, or don't understand that they could get a whole lot more out of their equipment if they engaged with it differently. The problem with this is you can't just pan from centre to hard right or hard left without losing signal in the opposite side completely. You'd have to go simulate a noisefloor on the other side manually, or use an impulse response of the room to make an accurate reverb.it's a lot more work than it's worth. This isn't to say that the Barbershop guys didn't do something like that, or just used stereo and ran it through some nice software to enhance the effect. Problem with mono though is:Some people in this gig have relatively low-noise systems but there's always room ambience. You can't take an incident sound which was recorded with no directional information and just drop it through one side of the headphones without the listener having a really jarring impression that the other side has lost its connection, or that someone has covered their ear with tape. That other ambient noise is really important to the overall impression.When we're talking about binaural specifically too, there's the added factor that what binaural does which separates it from everyday stereo stuff is it uses some other apparatus (or, rarely, processing) to simulate the other things the brain uses to extract spacial information from sound.
Namely, these are inter-aural time difference and inter-aural phase difference.You tell where a sound is with both ears, including the low-pass-filtered reflection of the sound which reverberates around the space to reach the far side of your head. The short difference in arrival time of the sound at different ears tells your brain something about the angle the sound is coming from. Phase is similar in that it's also time-based, but basically is about how the waveforms of that 'incident' and 'reflected' sound line up if they were placed on top of one another. More delay here means the two sounds are further out-of-phase with one another.Those two things are crucial to the binaural experience. The way it's most easily achieved is by putting a head-shaped object in between the two mics, and placing the mics themselves inside ear-shaped objects. One way.is in-ear binaural mics! Another is the infamous 3Dio unit.You probably didn't need this explanation but the more you know.
There's a live stream here:It is using a binaural dummy head, volume levels are important to be set that sounds like you are not wearing headphones, and hearing it as if you were there in the garden.The ear shape is VITAL that it resembles your own, if it does not, HRTF confusion would occur, tilting your head up, and down you may find that you get the best results not actually in a position where you are looking without tilting your head, especially if an aircraft goes over head. In November there were 17,000 visitors! It is located near Liverpool UK, so GMT. Nowt really happens at night, but you could have a few surprises as it's an urban area with foxes, hedgehogs, owls etc, with an occasional train in the distance. Please let me know what you think if you visit, for positional perception, and realism (or not) would be greatly appreciated.edit: If you close your eyes and imagine you are standing in a garden will help very, very much!. There's no 'ear shape consideration'Indeed, however, I was messaged by someone who had been listening to a lot of 3Dio recordings and they said after a long while of listening, that they started to perceive directions and other cues much better, perhaps it can be learned when combined with visual cues too. There was an experiment done many years ago (and more recent times) of having a user wear special glasses (all the time) that made everything up-side-down, after a period of time the brain switched, and they saw everything the right way up, the only down side was the brain had to relearn the process when the user took off the glasses.
But it did come to mind that perhaps the same could be held true with our hearing perception. Time will tell I guess. Here are some of my opinions of this classic. I think we definitely agree on some major points!I think the reason it works so well is because of the layers of sound they built in order to show off all the subtle features of the technology. It really is to ground the audio to a specific point in a room.By having the softer background noise of the guitar it grounds you in the room because it contrasts with the activity closer to you. I also believe this also sets off the near sounds more by giving it depth.
Another feature is the way that the main actor transitions around the room early makes it feel more natural than just moving simply from left to right, ear to ear, like so much of YouTube ASMR seems to be doing. Not knowing where or when the sound will come to which ear helps the stimulus, imo. All of this theater sets up the payoff at the end of the audio.I think there are a few channels that get the walking around the room thing down in the RP, but then just too easily slip into a steady left to right, top to bottom, pattern without variation.The focus has shifted to the specific triggers for channels that have the best sound quality and the RP has gotten to whispered and off what a good ASMR script entails. The whispered voice loses all impact for me when there is not contrast in tones or no reason for the whisper.
All in all there is a lack of composition to most of what is out there.
3D audio effects are a group of sound effects that manipulate the sound produced by stereo speakers, surround-sound speakers, speaker-arrays, or headphones. This frequently involves the virtual placement of sound sources anywhere in three-dimensional space, including behind, above or below the listener.[1]
3-D audio (processing) is the spatial domain convolution of sound waves using Head-related transfer functions. It is the phenomenon of transforming sound waves (using head-related transfer function or HRTF filters and cross talk cancellation techniques) to mimic natural sounds waves, which emanate from a point in a 3-D space. It allows trickery of the brain using the ears and auditory nerves, pretending to place different sounds in different 3-D locations upon hearing the sounds, even though the sounds may just be produced from just 2 speakers (dissimilar to surround sound).
Complete 3D positional audio[edit]
A sound is placed in the horizontal plane by processing the sound with recorded head-related impulse responses.
Using head-related transfer functions and reverberation, the changes of sound on its way from the source (including reflections from walls and floors) to the listener's ear can be simulated. These effects include localization of sound sources behind, above and below the listener.
Some 3D technologies also convert binaural recordings to stereo recordings. MorrowSoundTrue3D converts binaural, stereo, 5.1 and other formats to 8.1 single and multiple zone 3D sound experiences in realtime.
3D Positional Audio effects emerged in the 1990s in PC and Game Consoles.
3D audio techniques have also been incorporated in music and video-game style music video arts. The Audioscape research project, provides musicians with a real-time 3D audiovisual content authoring and rendering environment, suitable for live performance applications.

True representation of the elevation level for 3D loudspeaker reproduction become possible by the Ambisonics and wave field synthesis (WFS) principle, MorrowSound True3D and A&G 3D-EST.
3-D audio presentations[edit]
Some amusement parks have created attractions based around the principles of 3-D audio. One example is Sounds Dangerous! at Disney's Hollywood Studios at the Walt Disney World Resort in Florida. Guests wear special earphones as they watch a short film starring comedian Drew Carey. At a point in the film, the screen goes dark while a 3-D audio sound-track immerses the guests in the ongoing story. To ensure that the effect is heard properly, the earphone covers are color-coded to indicate how they should be worn. This is not a generated effect but a binaural recording.

These range from single 8.1 to 64.3 True3D installations, some interactive.
Nick Cave's novel The Death of Bunny Munro was recorded in audiobook format using 3D audio.
The song 'Propeller Seeds' by English artist Imogen Heap was recorded using 3D audio.
There has been developments in using 3D audio for DJ performances including the world's first Dolby Atmos event on 23rd Jan 2016 held at Ministry of Sound, London. The event was a showcase of a 3D audio DJ set performed by Hospital Records owner Tony Colman aka London Elektricity.
Other investigations included the Jago 3D Sound project which is looking at using Ambisonics combined with STEM music containers created and released by Native Instruments in 2015 for 3D nightclub sets.
