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://juneja.info/binaural/v-i-r-t-u-a-l-_-b-a.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.

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

    Is it me or all that’s required is a mic and a pretty good sound board that’ll pan and go up and down… Last I heard an algorithim is a mathematical calculation that in this case applied to a hearing aid can offer as good a sound as the natural hearing cavity. So, I suppose there will be no noble prize for discovering “america’ once more.

    Wow!
    I can only look forward to the new audio book recordings in 3D! It might be even better than a movie!
    Good job. now how can I record my guitar and singing to sound like this?

    woah?! Sooo fascinating! I want more! ;) ))

  4. Vijay says:

    Wow… amazing technology… I felt it like real when a cover was put on the head, and the trimmer machine and even tapping the head… gr8 technology… feel like how it would be if this technology is used for the songs….

  5. Noah Bamberger says:

    hey man excellent job, iv currently been doing the same thing with two microphones panned to each ear, but this is very limiting. where can i find the mathematical formula for this algorithm? would be a great help if anyone knows
