Your examples are not carrier waves (which are used by FM) but simple
AM. Bird songs do all those things. You can also look at the songs of
the humpback whales which convey a lot of information, just we do not
understand it all. I would postulate that the more complex the organism,
the more complex will be the song or language. Sort of fits with the
central processor: the more ram, the more it can do.
There is nothing stopping a song from being a short burst and the
receptor able to decipher those bursts. I believe some bats do that, but
will gladly bow to those more knowledgeable. In essence, I think we
already have what you are looking for all around us. Except FM carrier
waves. Too complex and too difficult to encode and decode.
