When you listen to music or other sounds, sometimes you can tell what they are without seeing them. For example, if you hear the sound of a bird chirping, you can guess that it's a bird making the sound. This is called "semantic audio."
Semantic audio is like a special language that computers use to understand the meaning of sounds. Just like how you learn words and what they mean, computers can learn to recognize sounds and figure out what they are.
To do this, computers use something called "machine learning." This means that they study lots of different sounds and figure out patterns in the sounds that match what we know about those sounds. Then, when they hear a new sound, they can compare it to what they've learned and make a good guess about what it is.
Semantic audio is really useful for things like music recognition or automatic transcription of speech. It can also help people with hearing problems understand what's going on around them by converting sounds into words or descriptive text.
