DIRECTIONAL CODING CONVERSION

摘要

A directional coding conversion method and system includes receiving input audio signals that comprise directional audio coded signals into which directional audio information is encoded according to a first loudspeaker setup and extracting the directional audio coded signals from the received input audio signals. The method and system further includes decoding, according to the first loudspeaker setup, the extracted directional audio coded signals to provide at least one absolute audio signal and corresponding absolute directional information and processing the at least one absolute audio signal and the absolute directional information to provide first output audio signals coded according to a second loudspeaker setup.
