簡而言之，我在我的應用程序中使用 .ogg 文件，并且有幾個背景音軌需要循環播放。但是，我循環播放音頻文件的方法是簡單地重新加載音頻文件并再次播放。這種方法會在循環的每次播放之間產生延遲，這對于游戲所期望的無縫體驗來說是不理想的。有沒有一種方法我不必每次都重新加載文件？如有必要，我愿意將音頻文件保存在內存中。這是我的 Sound 類，它的功能有所減少，可以解決問題的核心：以下庫可能是播放某些文件類型所必需的，并且應該與上述文件一起編譯：（鏈接）對于未來的讀者，以防上述鏈接過期，使用的庫如下：jl1.0.1.jarjogg-0.0.7.jarjorbis-0.0.17-1.jarmp3spi1.9.5.jarvorbisspi1.0.3.jar使用這個 Sound 類和這個 ogg 文件（來自 Undertale 的 Spear of Justice），這是一個顯示問題的簡單類：import javax.sound.sampled.UnsupportedAudioFileException;import java.io.IOException;public class Test { public static void main(String[] args) throws IOException, UnsupportedAudioFileException, InterruptedException { //Replace the path with the path to the downloaded soj.ogg file or another test file Sound spearOfJustice = new Sound("C:\\Users\\gigibayte\\Desktop\\soj.ogg", true); spearOfJustice.play(); //Ensure that this is greater than or equal than the length of the audio file chosen above in seconds. int songSeconds = 240; //Song is played twice to show looping issue Thread.sleep(songSeconds * 2 * 1000); }}

實際上，解決方案比我想象的要容易得多。我只是將 do-while 循環移動到流方法并相應地進行了更改。
PlayingSound() {
Thread playingSound = new Thread(() -> {
//REMOVED THE DO WHILE LOOP HERE
try {
AudioInputStream in;
in = getAudioInputStream(new File(fileName));
final AudioFormat outFormat = getOutFormat(in.getFormat());
final Info info = new Info(SourceDataLine.class, outFormat);
try(final SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info)) {
if(line != null) {
line.open(outFormat);
line.start();
AudioInputStream inputMystream = AudioSystem.getAudioInputStream(outFormat, in);
stream(outFormat, inputMystream, line);
line.drain();
line.stop();
}
}
}
catch(UnsupportedAudioFileException | LineUnavailableException | IOException e) {
throw new IllegalStateException(e);
}
finally {
removeInternalSound(this);
}
});
playingSound.start();
}
/**
* Streams the audio to the mixer
*
* @param in Input stream to audio file
* @param line Where the audio data can be written to
* @throws IOException Thrown if given file has any problems
*/
private void stream(AudioFormat outFormat, AudioInputStream in, SourceDataLine line) throws IOException {
byte[] buffer = new byte[32];
do {
for(int n = 0; n != -1 && !stop; n = in.read(buffer, 0, buffer.length)) {
byte[] bufferTemp = new byte[buffer.length];
for(int i = 0; i < bufferTemp.length; i += 2) {
short audioSample = (short) ((short) ((buffer[i + 1] & 0xff) << 8) | (buffer[i] & 0xff));
bufferTemp[i] = (byte) audioSample;
bufferTemp[i + 1] = (byte) (audioSample >> 8);
}
buffer = bufferTemp;
line.write(buffer, 0, n);
}
in = getAudioInputStream(new File(fileName));
in = AudioSystem.getAudioInputStream(outFormat, in);
} while(loopable && !stop);
}
