How Does Reverb Actually Work?

[00:00:00]How does reverb actually work? When you hear a sound, it goes straight to your ears, but it also bounces off everything around it. This collection of delayed reflections is what we call reverb. This tells our brain how big the space is, how far away the sound is, and even what the room is made of. That's why a clap sounds bright in a bathroom, but huge in a cathedral.

[00:00:23]In the digital world, a plugin makes thousands of tiny copies of your sound and delays and shapes each one of them to simulate a space. Some reverbs simulate real spaces, and others, like plate reverbs, simulate large sheets of metal that vibrate when sound goes through them. Those vibrations are then captured by microphones, creating a smooth, dense sound. Just like this.

[00:00:46]Love this effect? You can get a free plate reverb along with seven other world-class UAD plugins with Universal Audio's Explore Bundle. Nice.
