OpenAL and DSP

[Nonni]

Hi,
Does anyone know how I can access the data that is currently being played in OpenAL ?
I've skimmed the OpenAL tutorials on lwjgl.org and I'm not sure how to do this.

I'm going to create a game that relies highly on Digital Signal Processing. That is, I will run FFT and plot both the spectrum and oscilloscope. I will also use the data for beat detection.

I've done all those thing in FMOD 3 and C++ which is pretty straight forward with FMODs callback functions, but I wanted to give LWJGL a try.

So if you know a good tutorial or info on how to access these buffers in OpenAL please let me know.

Thanks.
