使用naudio播放byte [] [英] playing byte[] using naudio

问题描述

1. 如何将音频文件转换为byte []并使用Naudio播放? (代码将不胜感激)

2. 也与上面的问题有关，如何使用Naudio在Resource中播放音频文件? 对于第二个问题，我有以下代码:

1. How can I convert an audio file to byte[] and play it using Naudio? (code will be appreciated)

2. Also related to question above, how to play audio file in Resource using Naudio? For the second question I have this code:

IWavePlayer waveOutDevice;
IWaveProvider provider;

public void PlaySound(byte[] sound)
{
  waveoutDevice = new WaveOutEvent();
  provider = new RawSourceWaveStrem(new MemoryStream(sound), new WaveFormat();
  if (waveOutDevice != null)
  waveOutDevice.Stop();
  waveOutDevice.Init(provider);
  waveOutDevice.Play();

}

然后在我的表单构造器中执行类似的操作-

In my form constructor I then do something like -

PlaySound(Properties.Resources.beepsound)

哔哔声是声音文件....但是调用此方法时，我只是听到声音.有什么问题吗?

beepsound being the sound file....but I just hear a noise when this method is called. What could be wrong?

推荐答案

WaveFileReader类可以接受Stream作为参数，因此您可以使用MemoryStream封装byte[]缓冲区，其内容如下已从文件加载.

The WaveFileReader class can accept a Stream as a parameter, so you can use a MemoryStream to encapsulate a byte[] buffer whose contents you have loaded from a file.

类似这样的东西:

byte[] fileContent = File.ReadAllBytes(@"C:\Some\File.wav");
var waveFileReader = new WaveFileReader(new MemoryStream(fileContent), true);

您可以使用GetManifestResourceStream或类似方法来获取资源流并使用它.如果要重用这些流，请将false作为第二个参数传递，这将阻止它们与WaveFileReader实例一起处置.

You can use GetManifestResourceStream or similar to get a stream for a resource and use that. If you want to reuse the streams, pass false as the second parameter which will stop them being disposed along with the WaveFileReader instance.
