See how much level you can raise before a signal clips at 0 dBFS.
Headroom is the distance from your hottest peak to the zero full-scale ceiling, and the max boost shows how far the target ceiling allows. A true peak ceiling of -1 dBFS prevents inter-sample clipping, so headroom planning keeps loud masters from distorting on playback.
