Noise layering
Noise samples like vinyl crackle, tape hiss or electrical noise can help you layer mojo into a pristine mixdown. While a lot of analogue-emulation plugins can generate faux noise, you’ll find that adding noise via an audio stem is much more flexible. You can remove the noise completely when it’s not needed, ride the volume level to taste, or sidechain it against prominent mix elements such as the kick/ snare drum or bass. Processing your noise track with EQ will then help you restrict the noise’s frequencies and fit it in the mix.
