[Interest] Qt audio visualizer?

[Murphy, Sean M.]

Whoops, I didn't realize there was a demo included with the Qt distribution...  That makes it pretty easy!

Thanks for the pointer.

Does something along those lines.  I think it is the same thing that ended up in demo:

Hope this helps,

It might be possible for me to twist that into what I need - not sure if ALSA will work on Mac?  But if there is something more ready-made for cross-platform Qt, I'd rather start there...
