## What is Rum?

RUM simulates different kinds of rooms – from acoustically 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 acoustic instruments in order to breathe life into a dry sound source.
In addition to the ten multi-recorded rooms (with different mic settings and characters that can be cross combined) there’s an advanced stereo spread and modulation unit for even more tweakability.
This plug-in also comes with low cut and high cut filters, pre-delay (with tempo sync), a full set of factory presets and a built-in ducker making it easy to tame transients on the wet signal.
Feature list:
• 10 different rooms with 6 variants each
• 3 different types of stereo spread algorithms
• Modulation
• Ducker (compression) for the wet signal
• Pre-delay with tempo synchronization
• Low cut and high cut filters
• Plenty of factory presets
