In laymen terms, sidechain helps your leading elements stand out while ducking the volume of other sounds that get played at the same time. Sidechaining works a little bit differently, by making sure a particular sound is compressed, relative to other sounds or channels in your mix. Generally speaking, most compressors work on their own and focus on controlling the output of a single channel in your mix. So no matter what genre of music you listen to, your favourite songs are sure to use some sort of compression. Compression is one of the most popular tools used in professional audio recording, producing, and performances.
