Glue Compression
Definition
Light, transparent compression applied to a group bus or mix bus to make individual elements feel cohesive and unified, as though they share the same acoustic space.
In Simple Terms
Light compression on a group of tracks that makes them feel like a single, unified sound instead of separate recordings. It's the difference between instruments playing in the same room versus pasted together from different sessions.
In Practice
A 2:1 ratio bus compressor with moderate attack and release applied to the drum bus glues the individual kit microphones into a single, coherent instrument.
Common Confusion
Glue compression is not about loudness or punch — it is about cohesion. The gain reduction is gentle (1–3 dB), the ratio is low (1.5:1–2:1), and the goal is to make separate elements feel like they share the same room and the same air. If you can hear it working, you have already gone too far.
