I'm developing an animal that can do three things:
- Memorization of sound
- Long-distance sound "teleportation."
How could my animal's abilities work in reality?
Memorization of sound
The animal (a bird, if you must know) needs to be able to "record" every sound it makes and hears. Every. Single. Sound. Think of it as a recorder. These birds have excellent hearing because of their sound manipulation (see below).
This means that the bird can mimic every sound it has ever heard (which is useful because it can remember every sound it has ever heard). It can talk using human voices, it can mimic tones and accents, speak different languages, etc. It is not intelligent enough to carry on an enlightened conversation, because it isn't good at connecting the dots between outside stimuli and words it says.
But it has one thing in its favor: it remembers every sound. Even if it can't understand. And these birds have great temporal sense, so you can get them to record sound from a specific time. They are usually trained with colored bands, with each combination and order of colors meaning a different command.
This makes them valuable. They are useful to police and to spies. They can be trained to repeat messages, even once. If you tell them a phrase, they can say it once and then not again or repeat it hundreds of times, depending on the command. Now imagine if they were messengers: but how would you get them to get to one specific person? Easy answer:
Long-distance sound "teleportation"
I want them to be able to send a message anywhere in the world. Obviously they can't communicate through a vacuum, but it should be easy for them to send sound through hundreds, even thousands of miles of stone or water. It should be relatively fast. Sound travels at $343m/s.$ (miles per second.) I'm willing to go transonic $(273−342m/s)$. Not subsonic $(\lt 273m/s)$.
Of course it will be hard to focus through sound and water -- that's why I'm giving my bird the power of raw force/vibration manipulation (which is what sound is.) It's not enough to create dramatic sonic weapons (to a limit). But it keeps the vibrations at the exact frequency and intensity throughout the journey.
If the bird is trained in some way to shift the message, it can relinquish this "coating" or "shield" and allow the sound to travel and disperse normally. This should be strong enough so that the mimicry is perfect and the sound-message can be "delivered" to a specific person, even in a crowd.
How would this work?
- The "sound shields"
- the specificity of the message & speed
- the mimicry
- the memorization
I need the sound shields to keep the sound intact and to work by manipulating the way vibrations spread. I need the specificity of the message to be able to target one person in a crowd from the other side of the Earth. I need the mimicry to be perfectly perfect, and the bird to memorize everything from a thunderclap to the sound of a pindrop, at the same time. The memory should record every sound through its entire life (around 60 years.) I'm wondering how to alter the brain/memory of the bird so it can do this.
