Abstract
The present invention relates to an apparatus and a method for processing an audio signal, and more particularly, to an apparatus and a method for efficiently rendering a higher order ambisonics signal. To this end, provided are an audio signal processing apparatus, including: a pre-processor configured to separate an input audio signal into a first component corresponding to at least one object signal and a second component corresponding to a residual signal and extract position vector information corresponding to the first component from the input audio signal; a first rendering unit configured to perform an object-based first rendering on the first component using the position vector information; and a second rendering unit configured to perform a channel-based second rendering on the second component and an audio signal processing method using the same.
