From audiosamples to frequency display
Posted on 2005-04-11
I've set up the Samplegrabber. I use it to display bitmaps. If there is only audio I use the samples to print some easy spectrum to show.
What I want is to make, based on the audiosamples, is (1) a equalizer display (some frequencies and the level) and (2) just a first visualisation (like in the mediaplayer) to get an idea how it is done.
So the question is, can someone give some links or better sourcekode examples how this is done. I'm using Delphi but VB and C examples will do!
