Java Sound & OpenAL
#1

Hi,
does anyone has experience with 3D Audio in OpenAL and Java. Are there any good tutorials for that?
thanks

There is the OpenAL lessons (google for it). There are joal and lwjgl ports (check their home pages) but they are both lacking lesson 8: “OggVorbis Streaming Using The Source Queue”.

I’m using openAL and it’s good - can’t remember where I found some tuts though, I’m sure it was the JOAL site…

I think that my first touch with OpenAL was at

Nice tutorials you have there!

Thanks for that. I googled a bit and found some information about EAX. Is that a good soulution?

EAX is only part of what is supported in some sound APIs (like the ones listed here)
You can use JOAL and LWJGL ports of openAL (as Tom has said) to give you your 3D positional audio. EAX allows real-time effects processing to produce Reverb, Chorus and other changes in the sound you hear. Generally used in games for simulating how sounds reflect off your surroundings. I think only the Creative range of audio cards supports EAX.

Ok,
thanks for this information.
I have another question. A normal 5.1 setup has in every corner a loudspeaker and one in the center. If I place the center speaker on top of the room, could I change the configuration of openal/eax/joal so, that the position of the speaker is on the top of the room now and not in the center any more?

I’ve not used any of the OpenAL extesion slike EAX, but as far as I can tell, no you can not change the speaker configuration.

If it is at all possible, it is done in the soundcard driver software. Check out the software that came with your soundcard.
