Multiband Sidechain Compression

Mulitband sidechain compression is where you use one audio signal to compress a certain range of frequencies of another. Why do this? Two situations where this can help you the most are trying to make a kick drum and bass guitar sit together and also getting vocals and guitars to sit well in the mix. The basic idea is to make the competing frequencies "duck" out of the way of each other so one doesn't mask the other. For example, we can make it so every time the lead singer is singing, the sidechain compression on the mid range of the guitars that shares similar frequencies get triggered to make way for the vocal. This way you can have guitars and vocals that are both in your face but aren't battling for space. Take a look at the video below to see how we achieve this.



You could even take this one more step further, by using the EQ8 and an audio effects rack you could split the signal into mid/side and have it only compress the mono data. But that's another video :)
