如何在C＃与C＃低延迟/非常小的延迟播放音频文件？ [英] How to play audio file in C# with low latency/very little delay in C#?

问题描述

我如何发挥在C＃中的音频文件（.MP3）具有非常小的延迟？我的意思是，该文件应该开始播放用户输入后，右边的比提供及更高版本。

How do I play an audio file(.mp3) in C# with very little delay? What I mean is, the file should start playing the right after user input is provided and later than that.

另外，我怎么能在同一时间玩两个并联的音频文件？

Also, how can I play two audio files in parallel at the same time?

推荐答案

我告诉你我是如何做到这一点使用DirectX AudioVideoPlayback：

I show you how I do this using DirectX AudioVideoPlayback:

public class MusicPlayer
{
    private static Audio m_Audio;

    private static void Loop(Object Sender, EventArgs e)
    {
        ((Audio)Sender).SeekCurrentPosition(0d, SeekPositionFlags.AbsolutePositioning);
    }

    public static void Dispose()
    {
        if (m_Audio != null)
        {
            m_Audio.Stop();
            m_Audio.Dispose();
            m_Audio = null;
        }
    }

    public static void Mute()
    {
        if ((m_Audio != null) && m_Audio.Playing)
            m_Audio.Volume = -10000;
    }

    public static void Play(String filePath, Boolean loop)
    {
        if (File.Exists(filePath))
        {
            Dispose();

            if (m_Audio == null)
                m_Audio = new Audio(filePath);
            else
                m_Audio.Open(filePath);

            if (loop)
                m_Audio.Ending += Loop;

            m_Audio.Volume = MusicSettings.Volume - 10000;
            m_Audio.Play();
        }
    }

    public static void Unmute()
    {
        if (m_Audio != null)
            m_Audio.Volume = MusicSettings.Value - 10000;
    }
}

您可以从这个片段开始。
