Example 1 with SF2InstrumentRegion

use of com.sun.media.sound.SF2InstrumentRegion in project jdk8u_jdk by JetBrains.

the class TestPreciseTimestampRendering method createTestSoundbank.

public static SF2Soundbank createTestSoundbank() {
    // Create impulse instrument
    // used to measure timing of note-on playback
    SF2Soundbank soundbank = new SF2Soundbank();
    float[] data = new float[100];
    Arrays.fill(data, 0);
    data[0] = 1.0f;
    byte[] bdata = new byte[data.length * format.getFrameSize()];
    AudioFloatConverter.getConverter(format).toByteArray(data, bdata);
    SF2Sample sample = new SF2Sample(soundbank);
    sample.setName("Test Sample");
    sample.setData(bdata);
    sample.setSampleRate((long) format.getSampleRate());
    sample.setOriginalPitch(69);
    soundbank.addResource(sample);
    SF2Layer layer = new SF2Layer(soundbank);
    layer.setName("Test Layer");
    soundbank.addResource(layer);
    SF2LayerRegion region = new SF2LayerRegion();
    region.setSample(sample);
    layer.getRegions().add(region);
    SF2Instrument ins = new SF2Instrument(soundbank);
