<h1>audio_exists</h1>
<p>This function returns whether a sound exists (<tt>true</tt>) or not (<tt>false</tt>). Note that if the index you search for has not been initialised previously, this function will cause an error as it is searching for non-existent asset indices. The
sound to check can either be a single instance of a sound (the index for individual sounds being played can be stored in a variable when using the <a href="audio_play_sound.htm"><tt>audio_play_sound()</tt></a> or <a href="audio_play_sound_at.htm"><tt>audio_play_sound_at()</tt></a> functions)
or a sound asset.</p>
<p> </p>
<h4>Syntax:</h4>
<p class="code">audio_exists(index);</p>
<table>
<tbody>
<tr>
<th>Argument</th>
<th>Description</th>
</tr>
<tr>
<td>index</td>
<td>The index of the sound to check the existence of.</td>
</tr>

<h4>Returns:</h4>
<p class="code">Boolean</p>
<p> </p>
<h4>Example:</h4>
<p class="code">if audio_exists(global.Music)<br/> {
<br/> audio_play_sound(global.Music, 0, true);<br/> }
</p>
<p>The above code checks to see if a sound exists. If it does it is set to play in a loop.</p>
