function rsc_import_images( $meta, $post, $is_update ) {
  $audioFiles = $meta['cfs_audio_file'];

  //directory to import audioFiles to
  $artDir = 'wp-content/uploads/audio_file/';

  //if the directory doesn't exist, create it
  if(!file_exists(ABSPATH.$artDir)) {
    mkdir(ABSPATH.$artDir);
  }
  require_once(ABSPATH . 'wp-load.php');
  require_once(ABSPATH . 'wp-admin/includes/image.php');
  global $wpdb;

    //let's get the image file name
    $new_filename = end(explode(".", $audioFiles));
   
    //move the file to our custom import folder
    if (!@fclose(@fopen($audioFiles, "r"))) { //make sure the file actually exists
      $siteurl = get_option('siteurl');
      @$auduploadfile =  basename( $audioFiles );
      $audfilename = basename( $auduploadfile );
    $audFileType = pathinfo($audfilename,PATHINFO_EXTENSION);
      $wp_filetype = wp_check_filetype(basename($audfilename), null );
     
      //create an array of attachment data to insert into wp_posts table
      $artdata = array(
        'post_author' => 1,
        'post_date' => current_time('mysql'),
        'post_date_gmt' => current_time('mysql'),
        'post_title' => sanitize_file_name($audfilename),
        'post_content' => sanitize_file_name($audfilename),
        'post_status' => 'inherit',
        'comment_status' => 'closed',
        'ping_status' => 'closed',
        'post_name' => sanitize_title_with_dashes(str_replace("_", "-", sanitize_file_name($audfilename))),
        'post_modified' => current_time('mysql'),
        'post_modified_gmt' => current_time('mysql'),
        'post_type' => 'attachment',
        'guid' => $siteurl.'/'.$artDir.$audfilename,
        'post_mime_type' => $wp_filetype['type']
      );
      
      $uploads = wp_upload_dir();
      $save_path = $uploads['basedir'].'/audio_file/'.$audfilename;

      //insert the database record
      $attach_id = wp_insert_attachment( $artdata, $save_path );
      
      $meta['cfs_audio_file']= $attach_id;
      
      
    }
  

  return $meta;
