Reverb is a classic mixing tool for adding width, but also that third dimension to your mix: depth.
By adding depth to your stereo image, you’re also expanding the stereo image as a whole. Reverb will give you more room for every sound to breathe and settle into the mix.
There are many different ways to use reverb and add space to your mix, but any reverb technique will add some degree of depth and spaciousness to your mix. And there are many types of reverb. Each is capable of adding a distinct vibe and depth to your mix.
Choosing the perfect type of reverb to give that extra space without drastically changing your audio’s character will take some practice. But when it comes to width, Hall reverb is a good place to start.
Don’t stop there though… all types of reverb can do wonders for adding three-dimensionality depending on your mix and production style. It can be useful to experiment with different reverbs for different tracks in the mix, or alternate dry tracks with reverb treated tracks. With small amount of effect, that can add unpredictable and variable spaciousness during the final mix.
Hot Tip: Using reverb with a short decay time will add a subtler reverb effect. It’s great for when you want to add width and depth without changing the overall character of a sound.
