Isn't there any 3d audio simulation software out yet?? - Page 2 - diyAudio

Try catt or ease.
I have nice experience with ease.

CARA! Does everything I want it to. 3D, 2D, auralization, etc.

You can draw just about any room, any shape, any speaker, any furniture.

http://www.cara.de/

I highly recommend it. About $80 US

mister twister told you the best particle animation software available on the market. the learning curve is really much more than steep, the price too. i dont know if your interest goes that far. within houdini you can model mainly everything. you only need to know every parameter of your soundwave and understand the correct expression . the functions needed for wave visualization are also included into maya unlimited. both have steep learning curves.
i believe you wanna model a horn or something like that.
mainly soundwave animation is not that hard, you need to know about collision detection and maybe a little bit of scripting language.
the beginning of the correct animation is modeling an arc, for example the form of a dome tweeter and let the correct amount of particles spread along this path. the rest is all based on your correct settings about the waves and the colliding object. the standard settings are often incursion angel = excursion angel.
animation with wavesound capturing in maya is possible.
the only thing you have to know about 3d software is: every solution is made of a bunch of workarounds.
hope this is useful for you,

greets,
flexus

To distill what flexus writes above for JinMTVT...

Are you ready for a thesis project in which the "tuition" is 5-10 grand?

Didn't think so.

Here is an example of what a prefessional HT designer goes through in acoustic modelling just for the subwoofers in a room...mind you, many of his installs are in the million dollar range so they can afford the resources needed to do this kind of modelling.

There is some FEM room modelling tools in SoundEasy but they are far less than what Keith is talking about in this post.

MJK: exactly !!! i also firmly belive that the room and it's accoustics are tied to every system just as much as all of the other parts, and using "generic" loudspeakers or designing without the room parameters and without designing the room is just ridiculous


MisterTwister: you probably can't see it because it doesn't yet exist

have you played with the ripple tank java app?
i mean played HOURS ..tried stuff
it is a very very very basic simulation tool
but yet have so many "revealling" features
you can actually see the diff. equations/systems wou've read about ...feel em

it would be the same thing with a complete sound 3d package .... another world


About 3d apps and particles ..
i have worked and studied in 3d graphics for games/movies .... have worked quite a bit in the gaming industry
the particle systems you list are seriously advanced,
even more when they started to throw in scripting possibilities ..wich makes it almost limitless
( limited by scripting boundaries )
but i have not played with scripting
worked with softimage, AliasWavefront, maya, xsi
and 3dmax alot ... only played with softimage particles
and 3dmax ones ...

i don't quite see though how you could code all of the different parameters of sound waves..but i guess that some system permit following properties for individual particle ? even then ..would be a serious task

the 3d software would be a big + for using the 3d modelling package

3dmax Design is probably the easiest for architect. type of 3d design ... inventor/Solid works stuff would also be very good for precise modelling
but their FEA stuff is "weird" and i don't know how one could adapt the FEA for anything other then their phisical simulations ...also very very expensive on computational side


Panomaniac :

WOWOW
what a nice link
looks like a very good software
http://www.cara.de/ENU/CARA/index.html
i'll definitly look it all
and if it is even interesting, i'll purchase it
80$ is ridiculous if it does even half of what is advertised

but again ..didn't see anything about speaker diffraction
the "3d" part seems very limited to regular room boundaries ...but they seem to have implemented alot of different materials!!!!

MJK: please take a look at CARA and let us know what you think ( limitations , maths behind is ok? stuff that only you ( and a limtied bunch of member ) can understand ) so us regular mortals can understand how it can be used better !

anyone ever used that software ?

there is even a demo

looks like it has a LOAD of features
works for diffraction

http://www.linearx.com/products/soft...5/LEAP5_01.htm

i'll try the demo tonight

once i read that hybrid techniques like this will be usable in realtime when graphics cards reach 2tflops and 1 gigabyte of memory
