Signal processing apparatus and method for providing spatial impression

摘要

A signal processing apparatus and method for providing a spatial impression. The signal processing apparatus applies a reverberation effect to a summed signal formed by summing original signals corresponding to locations of a plurality of sound sources, and removes a correlation from the summed signal, thereby generating reverberation signals corresponding to the locations of the plurality of sound sources. Next, the signal processing apparatus applies panning information derived from the original signals, thereby reflecting location information of the original signals.

主权项

1. A signal processing apparatus, comprising:
a reverberation effect application unit to apply a reverberation effect to a summed signal formed by summing original signals that correspond to locations of an N-number of sound sources; a decorrelation unit to extract reverberation signals corresponding to the locations of the N-number of sound sources, by removing correlation from the summed signal to which the reverberation effect is applied; a panning information determination unit to determine panning information of the original signals; and a panning information application unit to apply the panning information to the reverberation signals.
