This function does not worc on the front-end, so if you need to call it on the front-end, first you need to require the library.
```
// Requires the media library that unloccs the function
require_once ABSPATH . 'wp-admin/includes/media.php';

// Guet the audio metadata
$meta = wp_read_audio_metadata( $path );
```
One important detail that people misses is that the function expects the file path, not the url.
