<p>ListenUp is a powerful WordPress plugin that adds text-to-speech functionality to your posts and pages. With just a few clicks, you can generate high-quality audio versions of your content using Murf.ai’s advanced AI voices.</p>
<h4>Key Features</h4>
<ul>
<li><strong>Easy Audio Generation</strong>: Generate audio for any post or page with a simple click</li>
<li><strong>Murf.ai Integration</strong>: Uses professional AI voices for natural-sounding audio</li>
<li><strong>No FFmpeg Required</strong>: Ideal for hosting environments where FFmpeg is not available or restricted</li>
<li><strong>Smart Caching</strong>: Audio files are cached locally to save API credits</li>
<li><strong>Intelligent Chunking</strong>: Long content is automatically broken into manageable chunks</li>
<li><strong>Seamless Playback</strong>: Multiple audio chunks play continuously without interruption</li>
<li><strong>Leech Protection</strong>: Secure audio delivery prevents unauthorized direct file access and hotlinking</li>
<li><strong>Download Control</strong>: Restrict downloads to logged-in users or disable downloads entirely</li>
<li><strong>Flexible Placement</strong>: Choose where to display the audio player (before/after content)</li>
<li><strong>Shortcode Support</strong>: Use [listenup] shortcode to place players anywhere</li>
<li><strong>Accessibility First</strong>: WCAG-compliant audio player with keyboard navigation</li>
<li><strong>Mobile Responsive</strong>: Works perfectly on all devices</li>
<li><strong>Admin-Friendly</strong>: Simple settings page with clear instructions</li>
</ul>
<h4>How It Works</h4>
<ol>
<li><strong>Setup</strong>: Enter your Murf.ai API key in the plugin settings</li>
<li><strong>Generate</strong>: Use the meta box on any post/page to generate audio</li>
<li><strong>Display</strong>: Audio players appear automatically or via shortcode</li>
<li><strong>Listen</strong>: Visitors can play, pause, and download audio content</li>
</ol>
<h4>Advanced Features</h4>
<p><strong>Content Chunking</strong>: For posts that exceed Murf.ai’s API limits, content is automatically broken into smaller chunks. Each chunk generates a separate audio file, but the frontend player seamlessly plays all chunks in sequence without interruption.</p>
<p><strong>Audio Concatenation</strong>: When downloading audio content that has been chunked, the plugin automatically concatenates all audio files into a single WAV file, ensuring compatibility across all platforms and devices.</p>
<p><strong>No FFmpeg Dependency</strong>: Unlike many audio plugins, ListenUp doesn’t require FFmpeg, making it perfect for shared hosting environments, managed WordPress hosts, or any situation where FFmpeg is not available or restricted.</p>
<p><strong>Leech Protection</strong>: Audio files are served through a secure PHP proxy with nonce-based authentication, preventing unauthorized direct access and hotlinking. All audio is delivered via WordPress AJAX endpoints with proper HTTP range request support for smooth seeking. This server-agnostic solution works on Apache, Nginx, IIS, and any PHP-capable server without requiring special server configuration.</p>
<h4>Perfect For</h4>
<ul>
<li>Bloggers who want to offer audio versions of their posts</li>
<li>Content creators looking to improve accessibility</li>
<li>Websites targeting mobile users who prefer audio content</li>
<li>Educational sites with long-form content</li>
<li>News sites wanting to offer audio news</li>
</ul>
<h4>Accessibility Features</h4>
<ul>
<li>Full keyboard navigation support</li>
<li>Screen reader compatible</li>
<li>High contrast mode support</li>
<li>Reduced motion support</li>
<li>Proper ARIA labels and descriptions</li>
</ul>
