You'll need to use DirectX (DirectSound) or some similar API that is designed to allow the playing of multiple sounds at the same time.

blocks|key|1519114|text|在C#或VB.Net中，有一种简单的方法可以同时播放多个声音。您必须调用mciSendString()接口函数来播放每个.wav文件。你甚至不需要做多线程，除非你是循环播放。Here是一个使用mciSendString()创建的MusicPlayer类的完整工作示例。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1519115|//+Sound+api+functions
[DllImport("winmm.dll")]
static+extern+Int32+mciSendString(string+command,+StringBuilder+buffer,+int+bufferSize,+IntPtr+hwndCallback);|code-block|syntax|javascript|1519116|在上面的函数中，关键是第一个参数命令。只要您使用单独的命令名调用两个函数，它们将分别/同时播放。这是我在我的一个C#程序中所做的：|1519117|private+void+PlayWorker()
{
++++StringBuilder+sb+=+new+StringBuilder();
++++mciSendString("open+\""+%2B+FileName+%2B+"\"+alias+"+%2B+this.TrackName,+sb,+0,+IntPtr.Zero);

There is one simple way to play multiple sounds at once in C# or VB.Net. You will have to call the <code>mciSendString()</code> API Function to play each .wav file. You won't even have to do multi-threading, unless you are loop-playing. <a href="http://pastebin.com/TtrCdeER" rel="nofollow">Here</a> is a complete working example of a <code>MusicPlayer</code> class created using <code>mciSendString()</code>.

<pre><code>// Sound api functions
[DllImport("winmm.dll")]
static extern Int32 mciSendString(string command, StringBuilder buffer, int bufferSize, IntPtr hwndCallback);
</code></pre>

In the above function, the key is first parameter command. As long as you call two functions with a separate command name, they will play separately/simultaneously. This is what I did in one of my C# programs:

<pre><code>private void PlayWorker()
{
 StringBuilder sb = new StringBuilder();
 mciSendString("open \"" + FileName + "\" alias " + this.TrackName, sb, 0, IntPtr.Zero);
 mciSendString("play " + this.TrackName, sb, 0, IntPtr.Zero);
 IsBeingPlayed = true;
}
</code></pre>

EDIT: Added link to a working example.

You could do this:

<code>SoundPlayer</code> supports WAV Stream. You could

<ul>
<li>MIX samples you play 'by-hand' and,</li>
<li>Fake (get the WAV header from somewhere, it's not complicated).</li>
</ul>

And provide such stream as a parameter to <a href="http://msdn.microsoft.com/en-us/library/ms143770.aspx" rel="nofollow">the <code>SoundPlayer</code> constructor</a>.

That way you won't have to use somehow complicated DirectSound libraries, and still have mixing (multiple sounds at once).

blocks|key|217551|text|我猜在您的WAV事件(或您正在使用的任何东西)中，您正在使用接受WAV文件路径的构造函数创建一个新的SoundPlayer实例，然后调用它的Play方法。从理论上讲，这应该不会导致您遇到的“单声道”效果，因为Windows从Windows+98开始就能够同时播放多个WAV文件。我认为你听到的(基于我自己对这个类的使用)不是在第二个声音开始时第一个声音的中断，而是从磁盘加载WAV文件时整体播放暂停导致的小故障。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|217552|与其在每次按键时加载一个新的SoundPlayer实例，不如尝试创建一个类作用域的SoundPlayer对象数组，并在窗体的Load事件中从磁盘预加载它们。然后只需在按键时调用每个SoundPlayer的Play方法。这可能会解决你的问题，尽管我认为你仍然会以这种方式偶尔遇到问题。|217553|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I'm guessing that in your KeyPress event (or whatever you're using) you're creating a new instance of SoundPlayer using the constructor that takes a path to the WAV file, and then calling its Play method. In theory this shouldn't cause the "mono" effect that you're encountering, since Windows has been capable of playing multiple WAV files simultaneously since Windows 98. What I think you're hearing (based on my own use of this class) is not a cutoff of the first sound when the second starts, but actually a glitch that results from overall playback pausing as the WAV file is loaded from disk.

Instead of loading up a new instance of SoundPlayer on each key press, try creating an array of class-scoped SoundPlayer objects and pre-loading them from disk in your form's Load event. Then just call each SoundPlayer's Play method when the key is pressed. This may fix your problem, although I think you will still get occasional glitches this way.

I'm making a sampler program where each key from 1 to 9 will make a different sound.
Everything works fine, but when I press two (or more) sounds at the same time, the second one "kills" the first one.

I'm playing the sounds from .WAV files, using <code>SoundPlayer</code>. How can I solve this?

我正在制作一个采样器程序，其中从1到9的每个键都会发出不同的声音。一切正常，但当我同时按下两个(或更多)声音时，第二个声音会“杀死”第一个声音。我使用SoundPlayer播放.WAV文件中的声音。我该如何解决这个问题呢？
