示例1: main
import com.sun.media.sound.AudioSynthesizer; //导入方法依赖的package包/类
public static void main(String[] args) throws Exception
{
AudioSynthesizer synth = new SoftSynthesizer();
AudioFormat format = new AudioFormat(44100, 16, 2, true, false);
AudioInputStream stream = synth.openStream(format, null);
// Make all voices busy, e.g.
// send midi on and midi off on all available voices
MidiChannel ch1 = synth.getChannels()[0];
ch1.programChange(48); // Use contionus instrument like string ensemble
for (int i = 0; i < synth.getMaxPolyphony(); i++) {
ch1.noteOn(64, 64);
ch1.noteOff(64);
}
// Now send single midi on, and midi off message
ch1.noteOn(64, 64);
ch1.noteOff(64);
// Read 10 sec from stream, by this time all voices should be inactvie
stream.skip(format.getFrameSize() * ((int)(format.getFrameRate() * 20)));
// If no voice are active, then this test will pass
VoiceStatus[] v = synth.getVoiceStatus();
for (int i = 0; i < v.length; i++) {
if(v[i].active)
{
throw new RuntimeException("Not all voices are inactive!");
}
}
// Close the synthesizer after use
synth.close();
}
示例2: main
import com.sun.media.sound.AudioSynthesizer; //导入方法依赖的package包/类
public static void main(String[] args) throws Exception
{
// Create instance of the synthesizer with very low polyphony
AudioSynthesizer synth = new SoftSynthesizer();
AudioFormat format = new AudioFormat(44100, 16, 2, true, false);
Map<String, Object> p = new HashMap<String, Object>();
p.put("max polyphony", new Integer(5));
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]);
sample.setSampleRate(44100);
sample.setOriginalPitch(20);
sf2.addResource(sample);
SF2Layer layer = new SF2Layer(sf2);
layer.setName("test layer");
sf2.addResource(layer);
for (int i = 0; i < 100; i++) {
SF2LayerRegion region = new SF2LayerRegion();
region.setSample(sample);

}
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();
