<p>This plugin adds the <code>loading=lazy</code> attribute to <code>iframe</code> elements coming from oEmbeds. In WordPress 5.5, <code>loading=lazy</code> is added to images per <a href="https://core.trac.wordpress.org/ticket/44427" rel="nofollow ugc">#44427</a>, and in 5.7 it is being added to iframes as well per <a href="https://core.trac.wordpress.org/ticket/50756" rel="nofollow ugc">#50756</a>.</p>
<p>This plugin will be obsolete by the time WordPress 5.7 is released. When that happens, this plugin will do nothing.</p>

<p>This plugins adds possibility to place audio files into posts and pages using the oEmbed technology used by WordPress for other purposes (YouTube videos etc). Audio files are embeded using HTML5 audio tag, with Flash-based backup player for MP3 format for browsers that don’t support either HTML5 or MP3 format (Internet Explorer up to version 8.0, Firefox and Opera).</p>
<p>To put audio file into a post, simply enter the URL link to the audio file as separate paragraph. The plugin will convert it into the player on the page. See screenshots.</p>

<h4>The new Shortcode:</h4>
<p>I’ve added a simple Shortcode to give you the full control of your HTML5 Audio:</p>
<pre><code>[audio id="your-css-id" class="pb-html5-audio-element" mp3="audio.mp3" ogg="audio.ogg" wav="audio.wav" autoplay="on" loop="on" preload="on" controls="on" flash_fallback="on" hidden="off"]
</code></pre>
<p>All Parameters are optional, but you need to specify at least one Audio Source: mp3, ogg or wav.</p>
<p>Defaults:</p>
<ul>
<li>id (optional, will be auto generated by the plugin if you not provide an ID)</li>
<li>class = pb-html5-audio-element</li>
<li>autoplay = off</li>
<li>loop = off</li>
<li>preload = on</li>
<li>controls = on</li>
<li>flash_fallback = on</li>
<li>hidden = off</li>
</ul>
<p>Please note: The Flash Fallback works only with mp3 files!</p>
<p>Since version 2.3 you can use the Generator below your Editor in Posts and Pages.</p>
<h4>Use the Shortcode in your Theme</h4>
<p>If you want to place an Audio-Tag Player in your Theme, you can use the Shortcode via PHP:</p>
<pre><code><?php
echo do_shortcode('[audio mp3="audio.mp3" ogg="audio.ogg" wav="audio.wav" autoplay="on" loop="on" preload="on" controls="on" flash_fallback="on" hidden="off"]');
?>
</code></pre>
