java - 在程序中实现 JAVE

Question

我正在尝试使用 JAVE http://www.sauronsoftware.it/projects/jave/在 Windows 上的 java 程序中将 flac 转换为 mp3。我已经下载了源代码等，我想知道如何将其添加到我的程序中？

Answer 1

@Faendol:首先，您需要导入最新的 JAVE jar，即 jave-1.0.2.jar 您可以通过 google 搜索有关导入 jar 文件的信息。

现在我已经创建了独立的程序来将 wav 文件转换为 mp3。(只是为了给你一个简单的想法)。示例已测试。同样，您可以将其实现为 FLAC 文件。但我怀疑你是否可以用 JAVE 做到这一点，尽管它的网站说可以!

   public static void main(String[] args) throws IllegalArgumentException, InputFormatException, EncoderException, IOException, NoSuchAlgorithmException, InvalidKeyException, NoSuchPaddingException, IllegalBlockSizeException, BadPaddingException, InvalidAlgorithmParameterException, UnsupportedAudioFileException{

    String sourceFile = "D:\\source.wav";
    String targetFile = "D:\\target.mp3";


    int samplingRate = 16000;// this could be 8000, 16000 mono or 16000 stereo 
    int channels = 2;// this could be 1 for mono and 2 for stereo
    int bitRate = 190000;// this could be 128, 160, 190 kbps, etc..

    AudioAttributes audio   = new AudioAttributes();
    audio.setCodec("libmp3lame");
    audio.setBitRate(bitRate);
    audio.setChannels(channels);
    audio.setSamplingRate(samplingRate);
    EncodingAttributes ea = new EncodingAttributes();
    ea.setAudioAttributes(audio);
    ea.setFormat("mp3");
    File f = new File(sourceFile);
    Encoder e = new Encoder();

    System.out.println(e.getInfo(f));

    e.encode(f, new File(targetFile), ea);
