CX (noise reduction)

Okay kiddo, you know how sometimes when you're trying to talk on the phone or listen to music, there's a lot of noise around you that makes it hard to hear what's happening? Well, there are special tools that can help with that! One of them is called "cx" or noise reduction.

This tool is kind of like a special filter for sound. It works by listening to all the noises around you and then choosing which ones are important (like the voice of the person you're talking to or the music you're trying to listen to) and which ones are not important (like background noises or other people talking).

Once it decides which noises to keep and which to get rid of, it makes those important noises louder and the other ones quieter. That way, you can hear what's important without getting distracted or annoyed by all the other sounds around you.

Think of it like a magic wand that can separate the good sounds from the bad sounds and make them easier to hear. Pretty cool, huh?
