Rum offers a sophisticated simulation of various room environments, ranging from acoustically treated studio booths to everyday home spaces. This plug-in emulates the experience of recording an audio source in stereo from across the room, a technique often used to add natural ambiance and depth to acoustic instrument recordings. By recreating these spatial characteristics, Rum injects life and realism into otherwise dry sound sources, enhancing their presence and warmth in any mix.

The plug-in features ten meticulously multi-recorded rooms, each with six different microphone setups that can be combined for unique tonal results. It includes advanced stereo spread algorithms and modulation options, providing extensive control over the spatial image. These tools allow users to craft a wide range of immersive and dynamic reverberation effects, adapting to various production needs.

Rum also integrates a built-in ducker to manage transient peaks on the wet signal, ensuring clarity and balance without overwhelming the original audio. Additional controls such as tempo-synced pre-delay, low cut and high cut filters, and a comprehensive library of factory presets make it a practical and creative solution for adding natural room ambiance to any track.
