Hi Daniel and Jason,

Thanks for replying. What i am trying to do is to drive a graphical output
based on the changing values of the sound input -- something like a sound
visualisation, if you will. So, you see, i am trying to get the values in
the wave not the file, to affect my visualisation. Searching through the
library, it seems i find that there are functions to get values, but they
are the file values like file frequency 44100 for example. Am i on the right
track here? I'm sorry if this seems trivial to you, i just started on openAL
and i greatly appreciate the help so far.
