如何发挥用n音讯一个MP3文件 [英] How to play a MP3 file using NAudio

问题描述

WaveStream waveStream = new Mp3FileReader(mp3FileToPlay);
var waveOut = new WaveOut();
waveOut.Init(waveStream); 
waveOut.Play();

这将引发异常：

WaveBadFormat调用waveOutOpen

WaveBadFormat calling waveOutOpen

编码类型是MpegLayer3为n音讯。

The encoding type is "MpegLayer3" as NAudio.

我怎么能起到一个MP3文件，n音讯

How can I play a mp3 file with NAudio?

推荐答案

尝试是这样的：

class Program
{
    static void Main()
    {
        using (var ms = File.OpenRead("test.mp3"))
        using (var rdr = new Mp3FileReader(ms))
        using (var wavStream = WaveFormatConversionStream.CreatePcmStream(rdr))
        using (var baStream = new BlockAlignReductionStream(wavStream))
        using (var waveOut = new WaveOut(WaveCallbackInfo.FunctionCallback()))
        {
            waveOut.Init(baStream);
            waveOut.Play();
            while (waveOut.PlaybackState == PlaybackState.Playing)
            {
               Thread.Sleep(100);
            }
        }
    }
}

修改这个代码是已经过时的（涉及到n音讯1.3）。建议不要在n音讯的新版本。请参阅备选答案。

Edit this code is now out of date (relates to NAudio 1.3). Not recommended on newer versions of NAudio. Please see alternative answer.
