+<p>{{ domxref("AudioContext") }} 接口的<code>suspend()</code> 方法暂停音频上下文对象中的进度，并暂时剥离进程对音频设备硬件的访问权限, 减少CPU和电池的使用。 当程序在一段时间内不会使用音频上下文对象时，这个方法对减少硬件资源占用是非常有用的。</p>
+
+<p>若对{{domxref("OfflineAudioContext")}} 调用此方法，将会抛出 <code>INVALID_STATE_ERR</code> 错误。</p>

+<p>The following snippet is taken from our <a href="https://github.com/mdn/audiocontext-states/settings">AudioContext states demo</a> (<a href="http://mdn.github.io/audiocontext-states/">see it running live</a>.) When the suspend/resume button is clicked, the {{domxref("AudioContext.state")}} is queried — if it is <code>running</code>, <code>suspend()</code> is called; if it is <code>suspended</code>, {{domxref("resume")}} is called. In each case, the text label of the button is updated as appropriate once the promise resolves.</p>
