APPARATUS AND METHOD FOR ENCODING AND DECODING MULTI-CHANNEL AUDIO SIGNAL |
摘要 |
Disclosed is an apparatus for encoding and decoding a multi-channel audio signal. The apparatus for encoding the multi-channel audio signal groups channels of a multi-channel audio signal, eliminates redundant information between channels using a mixing matrix including phase information, converts a frequency of the signal, and encodes the signal. |

1. An apparatus encoding a multi-channel audio signal, the apparatus comprising:
a channel grouping unit to group channels based on a channel characteristic of the multi-channel audio signal; a signal converter to eliminate redundant information between the group of channels and to convert a frequency of the multi-channel audio signal to produce a frequency-converted multi-channel audio signal; a quantization unit to quantize the frequency-converted multi-channel audio signal to produce a quantized multi-channel audio signal; and an encoder to encode the quantized multi-channel audio signal. |
