Question

您好，尝试为立体声.wav文件创建标头编码正确的规范。单声道文件创建工作正常，而编写立体声的尝试似乎会缩短一半。相当确定它在标题部分中。下面展示了两个示例（单声道和立体声）。任何见解都将受到高度赞赏。

Mono标头-此代码很好

    FileStream fsOut = new FileStream(oPath, FileMode.Create, FileAccess.Write);
        BinaryWriter bw = new BinaryWriter(fsOut);
        fsOut.Position = 0;
        bw.Write(new char[4] { 'R', 'I', 'F', 'F' });
        bw.Write(Convert.ToInt32(length));
        bw.Write(new char[8] { 'W', 'A', 'V', 'E', 'f', 'm', 't', ' ' });
        bw.Write((int)16);
        bw.Write((short)1);
        bw.Write((short)1);
        bw.Write(samplerate);
        bw.Write((int)(samplerate * ((BitsPerSample * 1) / 8)));
        bw.Write((short)((BitsPerSample * 1) / 8));
        bw.Write(BitsPerSample);
        bw.Write(new char[4] { 'd', 'a', 't', 'a' });
        bw.Write(Convert.ToInt32(DataLength));

立体声-这仅记录了单声道的长度

            FileStream fsOut = new FileStream(oPath, FileMode.Create, FileAccess.Write);
        BinaryWriter bw = new BinaryWriter(fsOut);
        fsOut.Position = 0;
        bw.Write(new char[4] { 'R', 'I', 'F', 'F' });
        bw.Write(Convert.ToInt32(length));
        bw.Write(new char[8] { 'W', 'A', 'V', 'E', 'f', 'm', 't', ' ' });
        bw.Write((int)16);
        bw.Write((short)1);
        bw.Write((short)2);
        bw.Write(samplerate);
        bw.Write((int)(samplerate * ((BitsPerSample * 2) / 8)));
        bw.Write((short)((BitsPerSample * 2) / 8));
        bw.Write(BitsPerSample);
        bw.Write(new char[4] { 'd', 'a', 't', 'a' });
        bw.Write(Convert.ToInt32(DataLength));

Answer 1

所以问题出在我在体内写的正弦波，而不是标题。

立体声.Wav创作的标题部分
