Sound in 3d space
Hi all,
Here’s what I want to do. I want to have a camera moving through a 3d space, such as a hallway, and the hallway walls are lined with video clips.
I could do that, but what I want to know is if you can embed sound in 3d space relative to the camera position, so as it flies past the video, the sound fades in and out again as it passes by.
The only way I know how to do this would be to ‘fake’ it with sound editing programs and just try and match the timing up.
So yeah, is there anyway to position audio in 3d space?

Audio editing all the way.

Although, now that I say that, you *might* be able to use expression where the sound is linked to a Null object, and based on how far away and which side of the camera it’s on, it get’s louder and pans.
You might want to post this in the AE expressions forum.

of course, you’re absolutely right.
Still, you have to admit this would make a really interesting experiment. They do similar stuff in 3D where there is audio driven by the animation, and I’d love to see this in AE.

[Brossy] “The only way I know how to do this would be to ‘fake’ it with sound editing programs and just try and match the timing up.

You could do this using expressions. I did something similar once, but it was pretty rudimentary. The proper way to do it would be to find the position relative to the camera, and the relative angle from the view so that you could alter the levels of the right and left channels independently. It is a little complicated to set up, but then it gives you your results automatically.
I’ll try to re-hash my old expression with some new fangled techniques I didn’t know at the time if you think that would be helpful.

[Dave LaRonde] “AE certainly isn’t the best application going to create surround audio, so you’d end up in an audio application anyway.”
That’s a good point, but then the question becomes: did the original poster want true 5.1 audio or would stereo panning and levels suffice?

Filip has some nice sound expressions for volume (percentage control) and panning, here:

Thanks for the replies and discussion guys.
I thought it seemed a little too good to be true, :P.
Surround would be brilliant, but stereo with fading would be good enough for me to show off to my friends.
I’ll check out those links that were just posted.
Also, the main reason I didn’t post in expressions forum, is because expressions still scare me…

Is it possible to get these back online ? seems like they’re gone…
