Digital audio

Hey buddy! Have you ever heard a song on your tablet or phone? That's digital audio! It's how we listen to music and other sounds using electronic devices.

So, let's get into what digital audio is. Remember when you played with your toy drum or xylophone, and how the sound vibrated through the air to reach your ears? In the same way, music or sound waves can be produced using real instruments like a guitar, drums, or voice. These waves then go through a microphone, which changes them into an electrical signal.

The electrical signal is then transformed into a stream of numbers that represent the original sound. These numbers can be stored in a computer, CD, or other electronic devices as a digital file. This file then gets played back by another electronic device, which converts the numbers back into an electrical signal.

Finally, this signal gets turned back into soundwaves through the speakers or headphones, and ta-da! You can listen to your favorite song or podcast.

In summary, digital audio is a process of turning real-life sounds into numbers that can be stored and listened to with electronic devices. It's amazing how electrical signals can be transformed into something we can hear and enjoy!
