SIGNAL PROCESSING APPARATUS AND METHOD FOR PROVIDING SPATIAL

摘要

PURPOSE: A signal processing device and a method thereof are provided to reduce a memory demand by applying echo effects to a sound source. CONSTITUTION: An echo effect applying unit(201) combines original signals corresponding to sound source locations. The echo effect applying unit applies an echo effect to the combined signal. A correlation removing unit(202) removes a correlation from an FDN(Feedback Delay Network) receiving the echo effect. The correlation removing unit extracts echo signals corresponding to one or more sound source locations.
