Minim: performance issues
May 17th, 2010, 2:45am  
I'm using minim to draw the spectrum as following:
for(int i = 0; i < fft.specSize(); i++)
 {
   line(i, height, i, height - fft.getBand(i)*4);
 }

When I run it on xp machine, I sometime get breaking sound. If I run in on windows 7, it keeps making the breaking sound. my other mp3 players work fine (e.g. windows media player, winamp). Is there any way to improve minim performance?

Had a look at cpu usage and realised it uses over 80% of my cpu most of time. when using other players like wmp or winamp, only 5%-9% is consumed. Any clues?

found problem cause now. it's caused by stroke(alpha). when i set alpha=128, it became extremely slow. Then I change it to 255, everything works fine now.
