APPARATUS, METHOD AND ELECTROACOUSTIC SYSTEM FOR REVERBERATION TIME EXTENSION

摘要

An apparatus for reverberation time extension is provided. The apparatus includes a module for calculating wave field synthesis information, and a signal processor for generating a plurality of audio output signals for a plurality of loudspeakers based on the audio input signals that have been recorded by a plurality of microphones, and based on the wave field synthesis information. Further, the apparatus includes an operating unit for determining a virtual position of one or several virtual walls. The module for calculating wave field synthesis information is implemented to calculate the wave field synthesis information based on the virtual position of the one or several virtual walls. Further, the virtual position is adjustable by the operating unit for at least one of the virtual walls.
