adding sounds to pdf

I can understand the back compatibility requirements.
So the way things are: to insert an mp3 sound I have to use the "Insert
sound" technique in Rich Media.
As far as I can see this uses a video display window while playing the
sound. I am afraid this appears (to me) a little tacky.
I can cover up the video display before it plays with a "poster" - say an
image of a speaker.
But then the display still turns to an empty black video screen when the
sound is played.

What I would like is to enable the reader to play a sound file when
clicking on or hovering over an invisible window over the title of what
would be played.
I can do this using the button technique - but this only uses wav files and
my pdf will rapidly grow to gigabyte size.

Many thanks. I am a neophyte in these things.
What you say works - I shall need to set up a poster image to use with the
sound. In the advanced options I can set the sound to turn off when the
page is turned
I also found the following video which inserts a (wav) sound with a button.
This allows me to set up the button (border and fill) within Adobe. Its
suggestion is to turn off the sound by playing a silence wav file.
