Apparatus of generating multi-channel sound signal

摘要

An apparatus of generating a multi-channel sound signal is provided. The apparatus may include a sound separator to determine a number (N) of sound signals based on at least one of a mixing characteristic and a spatial characteristic of a multi-channel sound signal when receiving the multi-channel sound signal, and to separate the multi-channel sound signal into N sound signals, the sound signals being generated such that the multi-channel sound signal is separated, and a sound synthesizer to synthesize N sound signals to be M sound signals.

1. An apparatus of processing a multi-channel signal, the apparatus comprising:
a sound separator to receive a multi-channel signal and to determine a first number (N) of channel signals based on at least one of a mixing characteristic and a spatial characteristic of the multi-channel signal, and to separate the multi-channel signal into the first number (N) of channel signals, the first number (N) of channel signals being generated such that the multi-channel signal is separated; and a sound synthesizer to synthesize the first number (N) of channel signals to be a second number (M) of channel signals, wherein the sound separator comprises: a panning coefficient extractor to extract a panning coefficient from the multi-channel signal; and a prominent panning coefficient estimator to extract a prominent panning coefficient from the extracted panning coefficient using an energy histogram, and to determine a number of the prominent panning coefficients as N.
