转换字节数组为WAV文件 [英] Converting Byte Array to Wav file

问题描述

广泛研究的主题后，我已经达到了一个砖墙。

所有我想要做的就是添加的.wav文件集合到一个字节数组，一个又一个，并将其所有输出成一个完整的新创建的.wav文件。我所有的.wav数据提取到一个字节数组，跳过.WAV头和数据直行，然后当谈到其写入到新创建的.wav文件我得到这样一个错误：
ERROR1：javax.sound.sampled.UnsupportedAudioFileException：无法从输入流音频输入流
误差2：无法从输入流中获得音频输入流

在code是：

 尝试
    {
    字符串路径=*********;
    字符串路径2 =路径+newFile.wav    文件文件路径=新的文件（路径）;
    文件NewfilePath =新的文件（路径2）;    的String [] = folderContent filePath.list（）;    INT文件大小= 0;    的for（int i = 0; I＆LT; folderContent.length;我++）
        {
            RandomAccessFile的RAF =新RandomAccessFile的（路径+ folderContent [I]，R）;
            文件大小=文件大小+（INT）raf.length（）;        }    字节[] = FileBytes新的字节[文件大小]    的for（int i = 0; I＆LT; folderContent.length;我++）
        {
            RandomAccessFile的RAF =新RandomAccessFile的（路径+ folderContent [I]，R）;
            raf.skipBytes（44）;
            raf.read（FileBytes）;
            raf.close（）;        }    布尔成功= NewfilePath.createNewFile（）;    InputStream中的字节数组=新ByteArrayInputStream进行（FileBytes）;    AIS的AudioInputStream = AudioSystem.getAudioInputStream（字节阵列）;    AudioSystem.write（AIS，Type.WAVE，NewfilePath）;    }
 

解决方案

您的字节数组不包含任何标题信息这可能意味着AutoSystem.write不认为这是真的WAV数据。

你能为你的组合数据创建一个适合的头？

After extensive research into the subject I have reached a brick wall.

All I want to do is add a collection of .wav files into a byte array, one after another, and output them all into one complete newly created .wav file. I extract all the .wav data into a byte array, skipping the .wav header and going straight for the data, then when it comes to writing it to the newly created .wav file I get an error like: Error1: javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input stream Error2: could not get audio input stream from input stream

The code is:

    try
    {
    String path = "*********";
    String path2 = path + "newFile.wav";

    File filePath = new File(path);
    File NewfilePath = new File(path2);

    String [] folderContent = filePath.list();

    int FileSize =  0;

    for(int i = 0; i < folderContent.length; i++)
        {
            RandomAccessFile raf = new RandomAccessFile(path + folderContent[i], "r");
            FileSize = FileSize + (int)raf.length();

        }

    byte[] FileBytes = new byte[FileSize];

    for(int i = 0; i < folderContent.length; i++)
        {
            RandomAccessFile raf = new RandomAccessFile(path + folderContent[i], "r");
            raf.skipBytes(44);
            raf.read(FileBytes);
            raf.close();

        }

    boolean success = NewfilePath.createNewFile();

    InputStream byteArray = new ByteArrayInputStream(FileBytes);

    AudioInputStream ais = AudioSystem.getAudioInputStream(byteArray);

    AudioSystem.write(ais, Type.WAVE, NewfilePath);

    }

解决方案

Your byte array doesn't contain any header information which probably means that AutoSystem.write doesn't think it is really WAV data.

Can you create suitable header for your combined data?
