Producing top and bottom panning??

My moneys on wetteke, but I can't prove Outlaws is wrong.
 
at the moment i'm listening to a spangling accoustic guitar ON TOP of a nice thick layer of bass (and getting a stiff neck doing so, better ease up on the EQ!)
 
I got the info you're after...

Yes man it's possible to mix with azimuth and elevation, yes man it's psychoacoustics....

Did you know that our ears, lobe, pavillion, cartilage, etc process the sound BEFORE it reaches the little hole?

Everybody has his own HRTF, Head Related Transfer Function, and that's what gives us the full 3D reconstruction of sounds in our brain.

tha's why we can tell when a sound is coming from behing rather than front, from above or below, etc...

The HRTF is a bidirectionnal filtering function, whose frequency plot actually depends on the relative position of both the head and he sound source. that's why it's called head related.

Some dudes carried out maesurments on a standardized puppet, and cam up with packages of generic HRTFs, one for a 30° elevation with 15° azimuth, same with 5° increments... etc

Impulse responses also capture the 3"Dimensionality" of real acoustic spaces... there's a huuuuuuge project on auralization for symphonic ensembles where the composer will be able the reconstruct a virtual take with genuine 3D sound field reconstruction from a huge collection or impulses and technic data on sound diffusion patterns for each instruments...
 
schnoops:
Yes man it's possible to "mix" with azimuth and elevation, yes man it's psychoacoustics....


How? :(



Yes schnoops, our brain can interprit sound from up and down but the question is still unanswered as to how to get an up and down "mix" from two speakers or a surround system........?
 
I'd Like to know too!

I'd like to let people know that I didn't have any luck getting that effect and the results we not even questionable. I'm not even going to waste mine time along with everyone else's for listening and uploading them to the web..

If someone does find out how to achieve this and can run through the steps to make this happen, I'd like to know too.

Ok, everybody try this, sit in front of your monitors in the sweet spot and put on some music which has a nice spectral balance with a lot of high freq detail etc. , sit upright with your head facing straight and level and listen to the sound, now slowly drop your head until your chin rests on your chest and the top of your head is pointing towards the monitors. See how the sound changes ? This is the effect that the shape of your ears has on sound entering from different angles.
 
Sure vox, I know what you mean. We've prove quite convincingly that we humans can hear shit above our heads. Point of this thread is how to achieve that with a mix whilst just sitt'n there?
 
Wouldn't you be able to do it with one of those dummy heads? Since the microphones would be getting the same filtering that you would be hearing if you were in the room, couldn't you just point the top of the head toward the source and record? Wouldn't this reproduce those filters through the speakers and make you believe you're hearing a sound from above you? Or would your ears not be fooled and still tell you that the sound is coming from the speakers in front of you?

Outlaws, if you have any info on this stuff, I'm sure lots of people would like to hear it too... So you definitely wouldn't be wasting your time! :)

nup. Sorry tek. That stereo head things been discussed above a few times already. That just gives you a good stereo recording.
Not up and down.
Look, this tread is about how to get up and down out of a normal stereo mix. Im convinced it cant be done.
 
The stereo head thing was mentioned, but no one has said that it can't do above/below sounds...

Does anyone have one of those heads so they can give it a try?

mr. blue bear, could you please explain to us how this top-bottom thing works?????????
 
I'm sorry but I'll have to pullote the thread once again.

get a set of HRTF, and use a convolution plug to process your sound (stereo) and listen to the results with head phones.

I remember could I dl a set of HRTF from spinaudio's web site, they actually use this tech in their surround plugins, but I can't say more!

have a go on google
