Sound in space

January 31, 2008 | 10:48 am

Hello MAx users,

I wonder if anyone could give me a tip!

I want to make a sound that sounds like a spiral that start from the center and moves out from there.
I think it would be to easy to use only panning (L-R), frequency (Up – Down) and volume for the third axis.
Is there a better way to do it?

Thank you!

…by the way there are a lot of things that concern with acoustic
illusions that you may consider before,
as what you imagine is sometime not what you are going to hear…
(diane deutsch etc…)
i was creating a cube with sounds, and tried to move the faces of the
cubes toward and backwards from my head, but it’s really difficult to
give the sensation of "a wall" with sounds.
It’s not easy to create with sound a very clear image, limited in space.

well…keep us updated..

hmmm…. thank you for that Tom , I am trying to figure it out how this external works..
I think it needs more channels (8) as I wanted to use. I was thinking about how to use spacial sounds within stereo channeling. I hope it is possible somehow… I am on it…

thanks

…sorry, it works in a way now…
I am investigating it, cool!

I think I need at least four channels for this object… I found something about Ambisonic UHJ format. Do you think there is something for this object, so the sound movements can be still recognizable in stereo?

cheers

there are binaural techinques i’m studying with a guy that developed
the algorithm for that
that convert whatever ambisonic format to binaural
with buffir objects and cutting frequencies wit different head models…
but it’s a bit complicated…

and its to be used with headphones , not in stereo

hi Tom,

ok, I would be also happy to use this object with binaural technic as well, I meditate with binaural beats… so it is possible I learn some new aspects of it…

… could you send me a link, please, where I can download this binaural object, what works with the aforementioned ambisonics external?

… if I can not hear spacial sound in the stereo speaker, I will use the headphones…:)

all the best,
krisztian

For full-sphere Ambisonics you need four
transmission channels and six, preferably
eight, speakers. This means that you need
a decoder to convert from one to the other.

Two-channel UHJ is a way of matrixing three
of the four transmission channels down into
two stereo-compatible channels. (This can
not be done without loss.) The one
transmission channel which is discarded is
Z which is used to encode height. So two-
channel UHJ is horizontal only. Horizontal
only is not what you originally wanted.

There is a four-channel version of UHJ which
includes height, but if you are going that
route you might as well use the raw
transmission channels (which are called
B-Format).

For more information on UHJ please see the
Ambisonic Surround Sound FAQ (which I
created and maintain):

Dear Martin,

I think I will have to read your FAQ. Everyday I understand more and more, whereby I see how much I need to learn…
thanks, I will try at least to find a why with binaurals…
all the best,

Hi,

you can also get some neat effects with ‘soundhack’ (free, Mac only),
GRM tools doppler (not free, Mac and PC) and if you search ‘doppler
vst’ or something like that you should find some usable stuff.

And if you want to read some other cool stuff you can check out
‘holophonics’ and ‘wave field synthesis’

Cheers,

Carey

On the PC side, I would recommend Adobe Audition (formerly known as Cool
Edit Pro). Apart from VST and DX compatibility, it has tons of high quality
built-in effects and excellent restoration tools. Doppler is also somewhere
in there. The best part is that it is both editor and multitrack DAW in one.
IIRC, educational price is a steal.
