<span>此类允许您查询和访问系统上安装的混音器。</span>
<span><code>AudioSystem</code>包括用于在不同格式之间转换音频数据以及用于在音频文件和流之间进行转换的多种方法。</span>
<span>它还提供了一种从<code><a href="../../../javax/sound/sampled/Line.html" title="interface in javax.sound.sampled"><code>Line</code></a></code>直接获取<code>AudioSystem</code>而不用混合器<code>AudioSystem</code>处理的方法。</span>
<p> <span>属性可用于指定特定行类型的默认调音台。</span> <span>考虑系统属性和属性文件。</span> <span>该<code>sound.properties</code>性文件从具体实现的位置读取（通常它是<code>lib</code>在Java安装目录的目录）。</span> <span>如果属性既作为系统属性又在属性文件中存在，则系统属性优先。</span> <span>如果没有指定，则在可用设备中选择合适的默认值。</span> <span>属性文件的语法在<code>Properties.load</code>中<a href="../../../java/util/Properties.html#load-java.io.InputStream-">指定</a> 。</span> <span>下表列出了可用的属性键和哪些方法考虑：</span> </p>

<p> <span>如果指定了提供程序类，并且可以从已安装的提供程序成功检索，则可以从提供程序<code>Mixer.Info</code>对象的列表。</span> <span>否则，或者当这些混音器不提供后续匹配时，该列表将从<a href="../../../javax/sound/sampled/AudioSystem.html#getMixerInfo--"><code>getMixerInfo()</code>检索</a>到包含所有可用的<code>Mixer.Info</code>对象。</span> </p>
<p> <span>如果指定了混音器名称，则会搜索所得到的<code>Mixer.Info</code>对象的列表：第一个具有匹配名称的对象，其<code>Mixer</code>提供相应的行界面将被返回。</span> <span>如果找不到匹配的<code>Mixer.Info</code>对象，或者未指定混合器名称，将返回提供相应行界面的结果列表中的第一个混合器。</span> <span>例如，财产<code>javax.sound.sampled.Clip</code>一个值<code>"com.sun.media.sound.MixerProvider#SunClip"</code>将产生以下后果时<code>getLine</code>被称为请求<code>Clip</code>实例：如果类<code>com.sun.media.sound.MixerProvider</code>在安装的混频器提供者列表存在，则第<code>Clip</code>从第一混频器与名<code>"SunClip"</code>将被退回。</span> <span>如果无法找到，第<code>Clip</code>从指定的供应商的第一混频器将被退回，无论名称。</span> <span>如果没有，第<code>Clip</code>从第一<code>Mixer</code>名称为<code>"SunClip"</code>在所有混合器（如返回列表<code>getMixerInfo</code> ）将被退回，或者，如果没有找到，第<code>Clip</code>第一<code>Mixer</code> ，可以在找到返回所有混音器的列表。</span> <span>如果失败，也会抛出一个<code>IllegalArgumentException</code> 。</span> </p>
