Web audio is what we hear when we use our computer or phone to listen to music or other sounds on the internet.
It works kind of like a big puzzle. There are different pieces that need to fit together to make it work.
First, there is something called a web browser. That's the tool that lets us look at websites on our computer or phone.
Then, there is something called "JavaScript". That's a special computer language that web developers use to make things happen on websites.
Next, there is something called an "audio context". That's like a little world where the sounds are created and put together.
Finally, there are different "nodes" that make up the sound. Think of nodes like different Lego pieces that we put together to make a cool structure.
All those pieces work together to give us the web audio we hear when we listen to music or other sounds online!
