Example 1 with SF2Layer

use of com.sun.media.sound.SF2Layer 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);
    ins.setName("Test Instrument");
    soundbank.addInstrument(ins);
    SF2InstrumentRegion insregion = new SF2InstrumentRegion();
    insregion.setLayer(layer);
    ins.getRegions().add(insregion);
    return soundbank;
}

Example 2 with SF2Layer

use of com.sun.media.sound.SF2Layer in project jdk8u_jdk by JetBrains.

the class NoteOverFlowTest2 method main.

public static void main(String[] args) throws Exception {

    AudioInputStream stream = synth.openStream(format, p);
    // Create instrument with too many regions (more than max polyphony)
    SF2Soundbank sf2 = new SF2Soundbank();
    SF2Sample sample = new SF2Sample(sf2);
    sample.setName("test sample");
    sample.setData(new byte[100]);

    }
    SF2Instrument ins = new SF2Instrument(sf2);
    ins.setPatch(new Patch(0, 0));
    ins.setName("test instrument");
    sf2.addInstrument(ins);
    SF2InstrumentRegion insregion = new SF2InstrumentRegion();
    insregion.setLayer(layer);
    ins.getRegions().add(insregion);
    // Load the test soundbank into the synthesizer
    synth.unloadAllInstruments(synth.getDefaultSoundbank());
    synth.loadAllInstruments(sf2);
    // Send out one midi on message
    MidiChannel ch1 = synth.getChannels()[0];
    ch1.programChange(0);
    ch1.noteOn(64, 64);
    // Read 1 sec from stream
    stream.skip(format.getFrameSize() * ((int) (format.getFrameRate() * 2)));
    // Close the synthesizer after use
    synth.close();
