How can I know the frame of an animation?

Hi all,
Someone could say me how can I know
the current frame of an animation being played?

I'm trying to imagine how could I do that
but it seems I'm quite stupid!

My goal is to play a sound in a specific frame
of the animation..

Thanks in advance!

regards,

This should help.
