Imperial Delay from Boz Digital is a delay plug-in that provides complete control over every nuance of a delay, while simultaneously being easy to use. The list of controls is comprehensive and each function can be adjusted with a single knob, but the unit also features advanced controls where deeper adjustments are required. The delays times can be free running, synced to host tempo, or entered using tap tempo.

The left and right delays have separate controls along with pitch shifting of the delays. Built-in ducking is available, where the direct signal brings down the level of the delay effect to avoid "overcrowding". Dynamic feedback has two levels of feedback, level-dependent on the loudness of the input signal. Smear provides a low-pass filter effect for placing the delay signal deeper into the background, with the effect applied progressively with each feedback pass.
