(Windows)"><code>winsound</code></a> module provides access to the basic sound-playing machinery provided by Windows platforms. It includes functions and several constants.</p> <dl class="py function"> <dt class="sig sig-object py" id="winsound.Beep">
+<code>winsound.Beep(frequency, duration)</code> </dt> <dd>
+<p>Beep the PC’s speaker. The <em>frequency</em> parameter specifies frequency, in hertz, of the sound, and must be in the range 37 through 32,767. The <em>duration</em> parameter specifies the number of milliseconds the sound should last. If the system is not able to beep the speaker, <a class="reference internal" href="exceptions#RuntimeError" title="RuntimeError"><code>RuntimeError</code></a> is raised.</p> </dd>
+</dl> <dl class="py function"> <dt class="sig sig-object py" id="winsound.PlaySound">
+<code>winsound.PlaySound(sound, flags)</code> </dt> <dd>
+<p>Call the underlying <code>PlaySound()</code> function from the Platform API. The <em>sound</em> parameter may be a filename, a system sound alias, audio data as a <a class="reference internal" href="../glossary#term-bytes-like-object"><span class="xref std std-term">bytes-like object</span></a>, or <code>None</code>. Its interpretation depends on the value of <em>flags</em>, which can be a bitwise ORed combination of the constants described below. If the <em>sound</em> parameter is <code>None</code>, any currently playing waveform sound is stopped. If the system indicates an error, <a class="reference internal" href="exceptions#RuntimeError" title="RuntimeError"><code>RuntimeError</code></a> is raised.</p> </dd>
+</dl> <dl class="py function"> <dt class="sig sig-object py" id="winsound.MessageBeep">
+<code>winsound.MessageBeep(type=MB_OK)</code> </dt> <dd>
+<p>Call the underlying <code>MessageBeep()</code> function from the Platform API. This plays a sound as specified in the registry. The <em>type</em> argument specifies which sound to play; possible values are <code>-1</code>, <code>MB_ICONASTERISK</code>, <code>MB_ICONEXCLAMATION</code>, <code>MB_ICONHAND</code>, <code>MB_ICONQUESTION</code>, and <code>MB_OK</code>, all described below. The value <code>-1</code> produces a “simple beep”; this is the final fallback if a sound cannot be played otherwise. If the system indicates an error, <a class="reference internal" href="exceptions#RuntimeError" title="RuntimeError"><code>RuntimeError</code></a> is raised.</p> </dd>
+</dl> <dl class="py data"> <dt class="sig sig-object py" id="winsound.SND_FILENAME">
+<code>winsound.SND_FILENAME</code> </dt> <dd>
+<p>The <em>sound</em> parameter is the name of a WAV file. Do not use with <a class="reference internal" href="#winsound.SND_ALIAS" title="winsound.SND_ALIAS"><code>SND_ALIAS</code></a>.</p> </dd>
+</dl> <dl class="py data"> <dt class="sig sig-object py" id="winsound.SND_ALIAS">
+<code>winsound.SND_ALIAS</code> </dt> <dd>
+<p>The <em>sound</em> parameter is a sound association name from the registry. If the registry contains no such name, play the system default sound unless <a class="reference internal" href="#winsound.SND_NODEFAULT" title="winsound.SND_NODEFAULT"><code>SND_NODEFAULT</code></a> is also specified. If no default sound is registered, raise <a class="reference internal" href="exceptions#RuntimeError" title="RuntimeError"><code>RuntimeError</code></a>. Do not use with <a class="reference internal" href="#winsound.SND_FILENAME" title="winsound.SND_FILENAME"><code>SND_FILENAME</code></a>.</p> <p>All Win32 systems support at least the following; most systems support many more:</p> <table class="docutils align-default"> <thead> <tr>
+<th class="head"><p><a class="reference internal" href="#winsound.PlaySound" title="winsound.PlaySound"><code>PlaySound()</code></a> <em>name</em></p></th> <th class="head"><p>Corresponding Control Panel Sound name</p></th> </tr> </thead> <tr>
