Yeah, you can access that data using get_post_meta, remember that almost everything in WordPress is a type of a post, an audio
its a wp_attachment
type, you just need the ID
, also you can make a shortcode
, this is an example:
function my_audio_func($atts) {
$audio_id = $atts['id']; //we need an ID as attribute
//we get the audio and the metadata
$metadata = get_post_meta($audio_id, "_wp_attachment_metadata");
echo "<pre>";
var_dump($metadata);
echo "</pre>";
//we get the post object to get the URL of the AUDIO
$audio = get_post($audio_id);
$audio_src = $audio->guid;//for object values is like this is an object
//
$attr = array(
'src' => $audio_src,
'loop' => '',
'autoplay' => '',
'preload' => 'none'
);
//display the audio player
echo wp_audio_shortcode($attr);
echo "<br/>";
//display the metadata ARTIST
echo $metadata[0]["artist"];//for metadata like this is an array
}
add_shortcode('my_audio', 'my_audio_func');
in your post use it like this:
[my_audio id="198"]
it will show like this:

this is all the metadata keys, the info you can get:
array(1) {
[0]=>
array(16) {
["dataformat"]=>
string(3) "mp3"
["channels"]=>
int(2)
["sample_rate"]=>
int(44100)
["bitrate"]=>
int(128000)
["channelmode"]=>
string(12) "joint stereo"
["bitrate_mode"]=>
string(3) "cbr"
["lossless"]=>
bool(false)
["encoder_options"]=>
string(6) "CBR128"
["compression_ratio"]=>
float(0.090702947845805)
["fileformat"]=>
string(3) "mp3"
["filesize"]=>
int(458918)
["mime_type"]=>
string(10) "audio/mpeg"

["length_formatted"]=>
string(4) "0:29"
["artist"]=>
string(6) "MY_ARTIST"
["album"]=>
string(5) "MY_ALBUM"
}
}
if you want the caption or name, that would be in the post object:
object(WP_Post)#587 (24) {
["ID"]=>
int(198)
["post_author"]=>
string(1) "1"
["post_date"]=>
string(19) "2017-09-26 15:54:30"
["post_date_gmt"]=>
string(19) "2017-09-26 15:54:30"
["post_content"]=>
string(38) ""My test audio"."
["post_title"]=>
string(35) "My test audio"
["post_excerpt"]=>
string(10) "MY_CAPTION"
["post_status"]=>
string(7) "inherit"
["comment_status"]=>
string(4) "open"
["ping_status"]=>
string(6) "closed"
["post_password"]=>
string(0) ""
["post_name"]=>
string(35) "my-test-audio"
["to_ping"]=>
string(0) ""

["post_parent"]=>
int(176)
["guid"]=>
string(97) "http://my_testsite.com/wp-content/uploads/sites/4/2017/03/my-test-audio.mp3"
["menu_order"]=>
int(0)
["post_type"]=>
string(10) "attachment"
["post_mime_type"]=>
string(10) "audio/mpeg"
["comment_count"]=>
string(1) "0"
["filter"]=>
string(3) "raw"
}
i commented in the shortcode how you can access values in the object and in the metadata array.
metadata
you talk about its the one for the audio shortcode, or for the audio file, everything hasmetadata
