I'm trying to analyse the sound being played out through the speakers so I can produce an accurate graphical representation (using vertical progress bars) of the "shape" of the sound. If you understand what I'm trying to do and can help us out I'd appreciate it.
I've tried playing around with the mixer API's but don't understand them enough (I can open the mixer device, but can't access the eq control)
Hope someone out there can help (even give me some source code to play with...hint hint!)
Thanx

The EQ won't help you. You need to open the device, then obtain the data. FFT should sort out the display.

Open it as what?
So what kind of device do I need to open it as then (as far as I can tell it can be a WaveOut, WaveIn, Aux, Mixer, and a whole host of other kind of devices).
Sorry...I'm new to sound/graphics programming

Use the WaveIn device for things coming in. WaveOut is only what has been played. I use an SB Live, which has a recording source of "What U Hear" which means that everything going out is mirrored in (like connecting line-out straight to line-in). I don't think you can get the mixed data that's going out. Anyone else know anything?

Thanx
Thanx but I've got it sorted now.
(not bothering programming anything :) Coz I've found somrething that does what I wanted to do)
