Standard audio compressors implement ballistics (attack/release) that define how compression behaves in time. Likewise, the HDR bus has user controls for the release time and shape, which let you define how the HDR window releases to a lower value. Figure 29.9, “HDR release: 0, 0.5 exponential, 0.5 linear, 1 exponential, 1 linear” shows various release times and modes. Adjust it to minimize artifacts such as pumping. Note however that there is no control for attack time, because the attack of an HDR system has to be instantaneous, like an audio limiter.
