Hi,
First of all let me remind you that the spectrum/wave display I wrote was only meant
as an example of how to use my XAudio component...
You're free to use and modify it, but it was not really meant as a display component
on it's own...
Having this said...
If you want to use more than one XAudio-player, the first thing you have to do is \
that you must work-around a bug in loading and unloading the DLL
It looks like when a second instance of the DLL is loaded, the first one disappears
because Delphi uses both components as a shared source.
This was something someone pointed me out a few days after I'd released the latest
version and I haven't had the time yet to take a look into it, sorry.
When using multiple players you have to make sure each of the players have
their own display (instance) initialized.
With another picture size you have to make sure the paint operations are also
adjusted to the new sizes (both vertical as horizontal).
Greetz,
Peter.

Subject: [xaudio-sdk] How to use two spectrums with Xaudio3295
Hi everybody,
How can i use two spectrum/wave with the new Xaudio3295 package.
It's only working when i init one of the two players.
And it seems that the spectrum is building outside the DisplayHeight and \
DisplayWidth. I use a smaller bitmap. How can i solve that.
I hope somebody have a solution.
Regards,
Eduard.
