[vinjn]

程序代码

import ddf.minim.*; 

Minim minim; 
AudioInput in; 

void setup() 
{ 
minim = new Minim(this); 
in = minim.getLineIn(Minim.MONO, 2); 
} 

void draw() 
{ 
float mic_volume = abs(in.left.get(0)); 
println("音量大小 = "+mic_volume*100); 
} 

void stop() 
{ 
in.close(); 
minim.stop(); 
super.stop(); 
}
