Hi there,
I'm trying to create a little visual effects program which uses OpenAL. The idea is to change the colours of the scene in time to a music track.
I was hoping to use the built in EFX equalizer as a spectrum analyzer. The four bands would be ideal for outputting to a graphics shader vector, as long as I have correctly "tuned" the frequency bands to the music I'm using. This would save me having to write any filtering functions.
So my question is: Is it possible to get the output levels of each band in the equalizer which are used in the final mix?
I don't need to hear the equalized track, so I can set the effects gain to zero. I will pay out the direct sound and hopefully just use the relative levels of the equalizer bands as some input to the graphics shaders.
Thanks,
Paul
