A scalable conferencing system can include a set of conferencing devices configured to be placed on a surface (such as, a table), mounted on a ceiling, or attached to a wall. The conferencing devices can be configured to be positioned in a room and pick up and/or reproduce audio in the room. Depending on the configuration and/or characteristics of the room (such as, dimensions, geometry, acoustical properties, furnishings, or the like), a plurality of conferencing devices of a particular type can be deployed in the room and/or conferencing devices of another particular type may not be deployed. The conferencing system can be used for audio and/or video conferencing.
