[Openal] <native device> and HRTFs

[Katharina Garbe]

Hi all,

 

after installing a Terratec DMX XFire 1024 Soundcard I can see with Everest
that my Terratec Soundcard supports DS3D as well as EAX 1 and 2.

When running the OpenAL samples I also see, that both ,generic hardware' and
,generic software' are supported.

 

Now I have several questions on OpenAL, HRTFs and <native device>:

 

1. What soundcard do I need to get <native device> supported? Does it have
to be a Creative's SB X-Fi? Or are other soundcards adequate, too? 
 
2. In addition, I need HRTF for my application . so, are there any external
soundcards (for mobile applications) that support <native device> as well as
HRTFs? I have seen the SB Audigy 2 NX
(http://www.creative.com/products/product.asp?category=1
<http://www.creative.com/products/product.asp?category=1&subcategory=205&pro
duct=9103> &subcategory=205&product=9103) and the SB Live! 24-bit External
(http://www.creative.com/products/product.asp?category=1
<http://www.creative.com/products/product.asp?category=1&subcategory=206&pro
duct=10702> &subcategory=206&product=10702) which kind of seem to fit to my
application. Also, in Germany there is the SB Surround 5.1
(http://de.europe.creative.com/products/product.asp?category=1

07&product=15912> &subcategory=207&product=15912) Card .

 

Having read this
http://opensource.creative.com/pipermail/openal/2007-February/010199.html
and
http://opensource.creative.com/pipermail/openal/2007-February/010261.html I
would much appreciate if someone could tell me which soundcard explicitly
supports <native device> as well als HRTFs or at least somehow
HRTF-functionality. 

 

3. Is HRTF-functionality = = EAX 5.0?

 

4. As an alternative: Is there anyone here who has implemented
HRTF-functionality on their own? Something like doing convolution in
real-time in software?

 

5. Other than that: Is there a possibility to use the
HRTF-software-algorithms of DS3D (I mean something like:
desc.guid3DAlgorithm = DS3DALG_HRTF_FULL;) via OpenAL?

 

Sorry, I know these are a lot of questions, but I am feeling kind of
confused with it all.

Looking very much forward to some answers .

 

. best,

 

Katharina
