将字节数组转换为wav文件

Question

I'm trying to play a wav sound that stored in byte array called bytes. I know that I should convert the byte array to wav file and save it in my local drive then called the saved file but I was not able to convert the byte array to wav file.

please help me to give sample code to convert byte arrary of wav sound to wav file.

here is my code:

protected void Button1_Click(object sender, EventArgs e)
{
    byte[] bytes = GetbyteArray();

   //missing code to convert the byte array to wav file

    .....................

    System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer(myfile);
    myPlayer.Stream = new MemoryStream();
    myPlayer.Play();
}

Answer 1

尝试这个：

System.IO.File.WriteAllBytes("yourfilepath.wav", bytes);

Answer 2

You can use something like File.WriteAllBytes(path, data) or...

...Alternatively if you don't want to write the file you could convert the byte array to a stream and then play that...

var bytes = File.ReadAllBytes(@"C:\WINDOWS\Media\ding.wav"); // as sample

using (Stream s = new MemoryStream(bytes))
{
    // http://msdn.microsoft.com/en-us/library/ms143770%28v=VS.100%29.aspx
    System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer(s);
    myPlayer.Play();
}

PK :-)

Using NAudio and you can try something like:

//var wavReader = new WaveFileReader(yourWavFilePath);
//byte[] buffer = new byte[2 * wav1Reader.WaveFormat.SampleRate * wav1Reader.WaveFormat.Channels];
byte[] buffer = YourWaveSoundByteArray;

using ( WaveFileWriter writer = new WaveFileWriter(YourOutputFilePath, new WaveFormat( AssignWaveFormatYouWant /*wavReader.WaveFormat.SampleRate, 16, 2/*how many channel*/))
    )
{
    //int bytesRead;
    //while ((bytesRead = wavReader.Read(buffer, 0, buffer.Length)) > 0)
    //{
        writer.Write(buffer, 0,  buffer.Length/*bytesRead*/);
    //}
}
