cetera Brain

3d Sound

New sound algorithm to create 3d effects in sound. You are femiliar with sterio, 5.1 surround etc things. But hear this mp3 using your head phones (head phone is a must). http://www.sajithmr.com/downloads/Barbershop.mp3

From this mp3 , you will get the feeling of a barber shop, and you are setting on the chair. If this mp3 makes you crazy ,it is nothing but cetera algorithm.

Starkey’s Cetera technology makes the hearing aid “invisible” to the brain. Cetera removes the barrier between sound and the brain’s ability to process signals. The Cetera technology is based on an innovative new algorithm- the complex mathematical formula that drives a hearing aid. Cetera’s algorithm can match the exact characteristics of the wearer’s ear. This customization removes the barrier that most hearing aids erect between the incoming sound waves and the data sent to the brain for processing.

Cetera Algorithm

Here is the full dialogs of this virtual barber shop:

Manuel - Hello there!Hello there!How are you?Yes, yes…You are here for the virtual haircut? yes, yes…ok… I will go and get Luigi.He will come and cut your hair… I’m Manuel, just stay right there.
Manuel – Luigi? (knock-knock) Oh Luigi? he’s present here for your virtual haircut. You’d better come up…..
LuigiGrazie* Manuel, I’m coming right now.

Manuel – He’s coming up right now and me I’ll go over here and play music, play the guittar because that’s what I do here at the barbershop.

Luigi - Ah, it’s so nice to see you.Welcome to the Starkey Cetera Barbershop and our virtual haircut. I’d like to start the demonstration by moving over to your right hand side and picking up this bag. If you just hold still for a second I’ll put this bag over your head! Just like that..The bag over the top of the head…

And now, I’ll take the bag off. There we go.

The only reason I did that it’s because all of the fancy barbershop do that.

What you’re listening to is I move to your right here and very quickly wash my hands

Trimmmm-Trimmm (the phone is ring) Manuueeellll could you get that please? Oh, thank you Manuel. Let me finish washing my hands here… just bear with a few more seconds.
Ah, yes… As I was saying, all we are doing is using your head as the listening point… and we have two microphones one on either side of the head, in the same position as where your left and your right ears are.

Your brain is doing all of the work, telling you where the sounds are coming from… ok…I’ll go and get the scissors… Nice sharp

And now as I begin the clipping and I bring the clip close to your ear, very close to the right ear…folow me as I move around the back of the head… to the left ear…and up over the top of the head…okay. Now, you can get the same effect better with the eletric razer, I’ll first bring it to your right ear…And around the back… and on your left. I think that looks wonderful. Manuel, what do you think?

Manuel – Ah? Yes..Ah, yes…It looks wonderful Luigi!You do such nice work

Luigi – Oh, thank you so much Manuel.

Manuel – So fast too.

Luigi - Now, as I walk around I just want to tell you only once more that your ability to hear where I am as I walk around the room is simply the amazing power of your brain, calculating the tinny differences or cues in sound intensity and arrival time from two open ears and unlike any other hearing instrument, only one has the digital algorithm that negates on physical presence in the ear to fully restore those differences.
And that algorithm is called… CETERA.

Oh, thank you, thank you so much for stopping by the Starkey Virtual barbershop

Good bye and arrivederte*

Okay … Some more virtual mp3s

    Thanksfor sharing this with us!I trulylike this objectand you are given here really a superbinformation.Thanks.Keep it up.keep up the high-qualityworks.keep blogging.

  2. Luigi says:

    Good bye and arrivederci (arrivederci means goodbye in italian)

  3. hi !

    where can I find anything about this algorithm? I’m studying on 3d sounds and want to know more about this algorithm.thanx in advance !

  4. I want more of these amazing 3d sounds!

  5. Rob says:

    Amazing!!

  6. Lon Xia says:

    Fantastic review, plenty of valid things in there which I am going to ought to look at just before paying for the cellular phone.

  7. socal frank says:

    On my system the surround effect only works for left – right – and rear. I don’t hear anything coming from the front perspective. It would need to be full 360, especially in the front, to be useful for theatrical applications.

    I work in motion picture sound and listened to the mp3 with excellent headphones.

  8. Seth says:

    They need to do this with porn….

  9. Celina says:

    The voice made chills run down my spine! That was amazing! lol, I was kinda scared too.

  10. Hey!!,
    i listened this a year or may be two before and only remembered the word cetera,whic luigi said very colose to ear, today i was just surfing and googled cetera and see i am here,
    nice job!!

  11. Ramthai says:

    Perfectly blended. Totally cool, hats off to you guys.

  12. Iron Bug says:

    I’m curious whether the algorithm is proprietary or under some free license? I would be glad to try it, since I’m a professional programmer and also play music. But I deal with open source platform and so that would only work if the algo is under GPL or so… Where I could find more info about it?

  13. Drags says:

    What can I say. It is a revolution. I am ultimately excited while and after listening any of demo mp3′s. I want this algorithm at large. Games, movies, phone calls, whatever…It is just awesome. Perfect. Thanks.

  14. Christian Hess says:

    Wow! That was awesome! my mom got me a latte espresso (portable mp3/wma player), and it had that virtual barber shop on it. i listened to it so many times. i was wondering if there is anything else like it.

  15. Marie Gahleitner says:

    Hello!

    I need urgently information about the Data of the VIRTUAL BARBER! Could it be used free in our acoustic institute or is it licenced? Do somebody has the name of the person who got the licence for the data?
    Our institute is called: European Research and Education Center for the Sustainable Development of Acoustic Space and was created in the context of Linz2009, European Capital of Culture.

    Thank you very much in advance for your answer.
    Best greatings from snowy Austria

  16. Dylan says:

    Holy shit.

    They need to make music like this!

  17. Sajith M.R says:

    Hey Recording guy,

    Please create one and post the link here, so that lots of people interested in that.

  18. recording guy says:

    Umm…. this needs an algorithm? “Binaural recording” with two microphones on either side of a “fake” head does this without an algorithm.

  19. Saurabh says:

    Awwwwwwssssoooooooommmmmmeeeeeeee!!!!!!!!!!!

  20. ivo dias says:

    very interesting …. this technology could be applied also in the MP4 movies.

  21. Paul Miller says:

    Thank you so much for making this publicly available. Apart from being brilliant clever, it was so real I was really shocked. Well done. I hope the technology spreads. It would be phenomenal for audio books and drama.
    I am sure that it will revolutionise the way that deaf people use aids, and probably be much appreciated by blind people too, as well as those of us who are fortunate to have our senses.

  22. Mr. Sims says:

    I can’t believe this hasn’t caught on yet! it’s 1000 times better than surround and at a fraction of the cost.

  23. Ben says:

    Is there anyone that sells a program that does this?

  24. Andre Rojas Flores says:

    i love it, but, i want the same … IN A BATTLE FIELD, WITH GUNS! GRENADES! EXPLOTIONS! WOW, T_T i cant find it … help
    jajajaja.jajaja@hotmail.com

  25. Ahmad says:

    Thanx so much for this .

  26. Cetera D. says:

    Thanks for naming an algorithm after me!
    This is really awesome just because I felt like I was really at a barber shop. I pinpoint the location of every sound I heard, to the point where I thought you were about to cut my ears off.
    Love it!

  27. aswath says:

    wow,,,, it was very nice to feel,,,, just imagine if we are seing a movie with same soung technology other than 5.1 or dts ……
    it was amazing……..
    and is it a software which is used for creating effect like this……????
    from whre ican read more about this software????

  28. Talal says:

    Hi everyone;
    thank you for this very interesting Mp3. PLEASE, could you send me an Algorithm as equations espatialy a elevation (vertical) palne.
    and if the frequency hase an effect.

  29. Someone in the internets says:

    Friggin amazing, wow, that is nice, don’t stop, keep up the good work.

  30. Anil Chandra says:

    wowwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww

    Wonderfull hats off for inventors of the Algorithm need moreeeeeeeee

  31. Liinkkkk says:

    amazing’ PLEASE put more mp3 like this to download, it’s better than a lot of normal musics. I hear barbershop when I go sleep’ lol

  32. mohamad khaneghai says:

    excuse me for spelling problems.i listen to it .it made me superised .thankyou.

  33. mohamad kh says:

    it is amazing and beuttiful .now i now more about it

  34. Brown-eyed says:

    http://www.alfa.lt/straipsnis/10272783
    this once is the best ;]]

  35. fernando says:

    This is just amazing!!
    Could anyone please tell me WHY I don’t have all my music and films in cetera algorithm? Where’s the problem? Who doesn’t want to pay who knows how much to whom?
    Is it possible to buy Zuccarelli Loudspeakers?
