Hi,
thank you for your reply, it has been very clear and it has solved all my
doubts.
I have downloaded and compiled osgAudio. Now I want to integrate it in my
own OSG-based program. So, how can I just open an audio file and play it? I
mean the simplest way, no need for complicated features right now. Something
like:
open("myAudio.wav");
playAudio();
Of course I understand that it is not so easy, but you can get an idea of
what I need at the moment.
Thank you in advance.

I want also to play other audio files (mp3, ogg, wav, whatever).

As the creator of osgAudio, I can answer this.
osgAudio is the literal and philosophical child of osgAL. We started
osgAudio using the osgAL source, fixed a number of design and implementation
issues, added compile-time selection of audio backend (openAL or FMOD) and
polished it up. Thus, osgAudio.
Even openAL's creator agrees that you should probably use osgAudio now,
since it has newer fixes.
OpenAL was LGPL, now proprietary (Creative Labs):
http://en.wikipedia.org/wiki/OpenAL
You'll have to interpret their licensing yourself.
There is also OpenAL Soft:
http://en.wikipedia.org/wiki/OpenAL#OpenAL_Soft
"OpenAL Soft is an LGPL-licensed, cross-platform, software implementation"
FMOD is proprietary but has a non-commercial license:
http://en.wikipedia.org/wiki/FMOD
"FMOD is available under multiple license schemes: FMOD Non-Commercial
License, which allows software not intended for commercial distribution to
use FMOD for free."
You could fairly easily add support for other backends to osgAudio if you
wished, but I'm not aware of too many other 3d spatial audio toolkits.
