problems with Sonia's connectLiveInput()
May 1^st, 2005, 4:50pm

hi,

i want to use connectLiveInput() to enables real-time FFT ananlysis of my Sample Object. then want to get the spectrum with sample.getSpectrum()
everythings seems fine, but when i'm running my code a nullpointerexception (at Sample.connectLiveInput) occurs.

my code:

Sample sound;

void setup(){
this.size(400,400);
Sonia.start(this); // Start Sonia engine.
this.sound = new Sample("test.wav");
this.sound.connectLiveInput(true);
this.sound.repeat();
}

void loop(){
background(55,55,55);
FFT();
}

private void FFT(){
sound.getSpectrum(2);
float volume = sound.getVolume();
}

the test.wav is located in the data folder.
where is the problem?
thx for help

I hope you have solved it. Is just that i got the same problem and got the solution. The problem was trying to connect to the Live Input without starting the LiveInput object.

This is my try:

Code:


void setup() { 
  size(640, 480); 
  Sonia.start(this);
  LiveInput.start();
  mySample = new Sample("test.wav");
  
  try {
    mySample.connectLiveInput(true);
  } 
  catch(Exception e) {
    println(e.toString());
  }
    
  mySample.play();
}
