我想知道两个音频文件是否相同或者一个包含另一个。

为此，我使用音乐指纹

byte[] firstAudio = readAudioFileData("first.mp3");
byte[] secondAudio = readAudioFileData("second.mp3");

FingerprintSimilarityComputer fingerprint = 
            new FingerprintSimilarityComputer(firstAudio, secondAudio);

FingerprintSimilarity fingerprintSimilarity = fingerprint.getFingerprintsSimilarity();

System.out.println("clip is found at " + fingerprintSimilarity.getScore());

要将音频转换为字节数组，我使用声音 API

public static byte[] readAudioFileData(final String filePath) {
    byte[] data = null;
    try {
        final ByteArrayOutputStream baout = new ByteArrayOutputStream();
        final File file = new File(filePath);
        final AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(file);

        byte[] buffer = new byte[4096];
        int c;
        while ((c = audioInputStream.read(buffer, 0, buffer.length)) != -1) {
            baout.write(buffer, 0, c);
        } …
