APPARATUS AND METHOD FOR VISUALIZATION OF MULTICHANNEL AUDIO SIGNALS

摘要

Provided are an apparatus and method for visualizing multichannel audio signals. The apparatus includes a spatial audio decoding unit for receiving a downmix signal of a time domain, converting the downmix signal into a signal of a frequency domain to output a frequency domain downmix signal, and synthesizing a multichannel audio signal based on the spatial parameter and the downmix signal; and a multichannel visualizing unit for creating visualization information of the multichannel audio signal based on the frequency domain downmix signal and the spatial parameter.
