KLEVGRAND Rum Room Simulator

Welcome
This is the user manual for Rum, a room simulator effect plug-in available for iPad (AUv3) and Mac & Windows (AU/VST3/AAX). It has been designed and developed by Klevgrand, a small studio in Stockholm, Sweden. Rum simulates different kinds of rooms – from acoustic treated studio booths to spaces found in an ordinary home. One can think of this plug-in as if the audio source was recorded in stereo from the other side of the room, a common technique for recording many acoustic instruments to breathe life into a dry sound source.
In addition to the 10 multi-recorded rooms (with different mic settings and characters that can be cross combined) there’s an advanced stereo spread and modulation unit for more tweakability. This plug-in also comes with a built-in ducker making it easy to tame transients on the wet signal, low cut and high cut filters, pre delay (with tempo sync) and a full set of factory presets.
