Adapting lux to render sound?

[Abel]

Very nice, congratulations! Even when not being physically correct, the resulting sound is very convincing. Even when listening to the piano video without watching, it gives a very spatial impression.

I do have a question though: somehow I would have expected a more pronounced stereo effect, are there technical reasons preventing that or do you somehow prefer the sound source to stay in a steady position?

Thanks Abel.

A good remark on the notion of stereo. The setup of both was indeed using a mono recorder. I did write some code for a stereo recorder, but never got around testing that thoroughly (for a very silly reason, my laptop is attached to an external screen, which makes that both mono and stereo sounds come from the right ). But you're very right I should try to come up with a stereo example too.

There is even an additional technique (which I did not implement) called HRTF [Head Related Transfer Functions] that model the effect the pinna (outer ear) has on the sound. That way you obtain the sound that actually would have reached our ear drums. Resulting in a very spatial impression, but only work using headphones.

Thanks again. Best,
Thomas

Amazing work! Added to bookmarks, will play with it a bit later during the couple of projects.

Thanks, I hope in time you'll let me know your first impressions

This would probably sound be better if my headphones worked properly, no?

As has been said, stereo simulation would be great, particularly if the ability to decide the distance between the "ears" was available. Pardon my ignorance, but what does this actually do? Does it output a sound file that sounds like you were travelling through the given environment? Anyways, I will have a play and let you know what I (in my very limited knowlege) think.

EDIT: What is that music? I'm guessing part of a Bach piece, but...

[thomas]

Yes headphones, especially the ones that work, do generally give a good impression, because they often distort the sound less than regular loudspeakers.

That's it in a nutshell. And yes do let me know.

Spot on, it's a prelude by Bach, it even has its own wikipedia page: http://en.wikipedia.org/wiki/Prelude_in ... r,_BWV_999 I use it for a lot of my projects, also for J.S. Bach on the Dance floor: http://thomaskrijnen.com/jsbotdf/jsbotdf.html

Don't be too impressed. I saw the Bach thing on your site before I asked. It's a nice piece.

A quick question: how would I get this to work? I've installed the addon, opened the example, and set the executable path to EAR.exe. However, clicking on "Render Audio" just gives me a blank console. Is this something I should expect, or have I done something wrong?

This, luxrender and a 3D screen could possibly make the most realistic CG video ever seen by man

New example, this time rendered in stereo. Overall the stereo effects are rather subtle (I think because of the enclosing walls omnidirectional reflection quickly get the upperhand). But if you watch it towards the end, I think the ball bouncing towards the middle is quite noticable.

Yes sir! Backdrop rendered in Lux, the bouncing ball in Blender Internal.

Also, keep in mind that since we all have different ears, HRTF effects differ slightly from person to person, so for the purpose of a video, perhaps a surround sound setup might work better. But yeah, someone should do this

Pilchard123 and others, a newer version is online at https://github.com/aothms/ear/downloads give it a try and if it still does not work please let me know.
