What you probably want is to use a PHP script that is masquerading as
the audio file. You can make a directory called 'my_song.wav', and have
an index.php inside that directory. At least with Apache, it will detect
the directory and instead load the index.php file. Your PHP code in that file can
introspect it's request with $PHP_SELF and find out what song was asked
for. Then, you can fopen() the real audio file (could be a sibling of
index.php, or in some other audio directory), and print it out to the
browser. Now your are in PHP, and you know that the request for the
song has been made. You won't be able to tell when the song
has finished, because there will be output buffering going on.
You may be able to do ob_start() before you print the .wav content,
then when you do ob_end_clean(), I would guess that when that statement
has finished you at least know that the server is done sending the
audio content. That still doesn't guarantee that the user has heard the
end of the song on their end however.
