<span><code>Encoding</code>类命名用于音频流的特定数据表示类型。</span>
<span>该编码包括除通道数，采样率，采样大小，帧速率，帧大小和字节顺序之外的声音格式的方面。</span>
<p> <span>一种普遍存在的音频编码类型是脉码调制（PCM），其仅仅是声波形的线性（比例）表示。</span> <span>使用PCM，每个样本中存储的数字与该时间点的声压的瞬时振幅成比例。</span> <span>数字可能是有符号的或无符号的整数或浮点数。</span> <span>除了PCM之外，其他编码还包括mu律和a律，它们是经常用于记录语音的声音振幅的非线性映射。</span> </p>
<p> <span>您可以通过引用此类创建的静态对象（如PCM_SIGNED或PCM_UNSIGNED）来使用预定义的编码。</span> <span>服务提供商可以创建新的编码，例如压缩的音频格式，并通过<code><a href="../../../javax/sound/sampled/AudioSystem.html" title="class in javax.sound.sampled"><code>AudioSystem</code></a></code>类使其<code><a href="../../../javax/sound/sampled/AudioSystem.html" title="class in javax.sound.sampled"><code>AudioSystem</code></a></code> 。</span> </p>
<p> <span><code>Encoding</code>类是静态的，所以具有相同编码的所有<code>AudioFormat</code>对象将引用相同的对象（而不是同一个类的不同实例）。</span> <span>这允许通过检查两个格式的编码相等来进行匹配。</span> </p>
