changereverberate

Changereverberate is a term used in audio processing to describe the operation of altering an existing reverberation effect. It typically refers to changing the characteristics of a reverb in real time or through automation within a digital audio workstation, a plugin, or a software synthesizer. The concept is to adapt the spatial and temporal qualities of the reverberation to suit a musical or sonic context.

Commonly adjusted parameters during changereverberate include decay time (the length of the reverb tail), room size, damping (high-frequency roll-off), pre-delay, diffusion, early reflections, and the wet/dry mix. Changes can be instant or smoothed over time, using envelopes, LFOs, or automated control data. In some systems, this also involves updating impulse responses or internal reverb state.

Applications include dynamic sound design for film and games, adaptive mixing in music production, and live performances where space or ambience shifts with scene or tempo. It enables scenes to become more intimate or expansive without changing the dry signal.

Practical considerations include potential artifacts from abrupt parameter changes, such as pops, clicks, or unnatural swells. Smoothing or ramping between states is common, and some reverb engines provide dedicated modulation options to minimize artifacts. Processing load and latency should also be considered in real-time contexts.
