Create a WordPress Template

I am in the middle of making a Wordpress site. On this page: [login to view URL] I have generated media players for multiple mp3 files in each media-page post—which are attached via a custom field group (using the plugin "Advanced Custom Fields Pro"). The players are ok except that you can't download the mp3 files and the client would like users to be able to download the mp3 files. What I would like to do is add a download icon to the right of each player, something like what I did on this (non-Wordpress) page: [login to view URL]~audreyvardanega/media/[login to view URL] The download link needs to download the mp3 file directly, NOT open a new page or popup with the default mp3 player from which you can right-click to download. It has to be a one-step click operation. This is the code that is being used to generate the players: <ul> <?php while( have_rows('mp3_files') ): the_row(); ?> <li> <h4 class="trackTitle"><?php echo get_sub_field('mp3_title'); ?></h4> <?php $audio = '[audio src="'.get_sub_field('mp3_file').'"]'; echo do_shortcode($audio); ?> </li> <?php endwhile; ?> </ul> So what I need is a direct download link that can access the mp3 files from the same source.
