Silhouette is a specialized plugin that takes a track and replaces it entirely with noise shaped to the exact dynamic profile of the track- use it to tell if you have a beat or just an over-compressed mess. It’s not exactly a pure gate with regular noise underneath: it’s calibrated to give a sense of what the dynamics really are, so it exaggerates those dynamics somewhat. This effect is built into Ditherbox as a mix check, but the standalone plugin version is free.
