One of the most commonly-used audio production tools is the reverberator. Reverberators apply subtle or large echo effects to sound and are typically used in commercial audio recordings. Current reverberator interfaces are often complex and hard-to-understand. In this work, we describe Reverbalize, a novel and easy-to-use interface for a reverberator. Reverbalize uses crowdsourced data to create a 2-dimensional map of adjectives used to describe reverberation (e.g. "underwater'). Adjacent words describe similar reverberation effects. Word size correlates with agreement for the definition of a word. To use Reverbalize, the user simply clicks on the descriptive adjective that best describes the desired effect. The tool modifies the sound accordingly. A text search box also lets the user type in the desired word.
