How to use

writeSamples

method

in

com.badlogic.gdx.audio.AudioDevice

  @Override
  public void run () {
    while (true) {
      recorder.read(samples, 0, samples.length);
      device.writeSamples(samples, 0, samples.length);
    }
  }
});

  @Override
  public void run () {
    final float frequency = 440;
    float increment = (float)(2 * Math.PI) * frequency / 44100; // angular increment for each sample
    float angle = 0;
    float samples[] = new float[1024];
    while (!stop) {
      for (int i = 0; i < samples.length; i += 2) {
        samples[i] = 0.5f * (float)Math.sin(angle);
        samples[i + 1] = 2 * samples[i];
        angle += increment;
      }
      device.writeSamples(samples, 0, samples.length);
    }
    device.dispose();
  }
});

public boolean write(float []buffer, int offset, int size)

    return true;
  } catch(Exception e) {
