Sonia & Dynamic Sample Size
Jul 30th, 2005, 9:31pm  
Hello,

don´t know anyone discuss about this before..

is there any way to generate a sampleobject with a dynamic size?
normally, i have to intialize a sample object like this:
sample [sampleNum] = new Sample(44100*SampleTime);

i look for a way to do something like:
record a sample as long as the mousebutton is pressed - without a pre-defined sampletime (otherwise i have somtimes soundobjects with a few seconds of silence, if the recorded sound is shorter than the pre-defined sampletime)

thanks & excuse my corrupt english...

this is a little (ugly) that hack should work, though im sure theres a nicer way:

Sample bufferSample;
public void mousePressed()
{
   int maxSampleLength = 10; // 10 seconds max
   bufferSample = new Sample(44100 * maxSampleLength);  
   LiveInput.startRec(bufferSample);
}

public void mouseReleased()
{
   LiveInput.stopRec(bufferSample);
   float[] frames = new float[bufferSample.getNumFrames()];  
   bufferSample.read(frames);
   int endframe = bufferSample.getNumFrames();    
   int zeroCounter = 0;  
   for (int i = 0; i < frames.length; i++) {
     if (frames[i]==0)
       zeroCounter++;
     else
       zeroCounter = 0;
     if (zeroCounter == 100)
       endframe = i;
   }
   println("sample length: "+endframe/44100f);    

   float[] data = new float[endframe];
   System.arraycopy(frames, 0, data, 0, endframe);

   Sample newSample = new Sample(data.length);
   newSample.write(data);
   newSample.play();
}

cheers,
daniel
