• Do you mean that the second URL works and you just want a way to edit the first string so that is matches? - You could do something like $string = str_replace( 'domain', 'sub.domain', $string); – Q Studio Commented Dec 21, 2020 at 12:55
• Or check out this filter - developer.wordpress/reference/hooks/wp_get_attachment_url – Q Studio Commented Dec 21, 2020 at 12:58
• I do not know how to please embed in my code – sa eu Commented Dec 21, 2020 at 13:16

$mp3Link = wp_get_attachment_url($mp3_file_id);
$mp3Link = str_replace( 'example', 'sub.example', $mp3Link ); 
<a class="w3-black" href="'.$mp3Link.'" rel="nofollow" >mp3</a>

replace example with your actual domain - it's not the most elegant solution, but might work.
