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.
摘要:
A method and apparatus to encode and decode an audio/speech signal is provided. An inputted audio signal or speech signal may be transformed into at least one of a high frequency resolution signal and a high temporal resolution signal. The signal may be encoded by determining an appropriate resolution, the encoded signal may be decoded, and thus the audio signal, the speech signal, and a mixed signal of the audio signal and the speech signal may be processed.

摘要:
Disclosed is an apparatus for encoding and/or decoding an audio signal having a variable bit rate (VBR). A target bit rate is determined in accordance with characteristics of an audio signal, and a weighted linear predictive transform coding is performed in accordance with the determined target bit rate.
摘要:
An apparatus and a method to encode and decode a speech signal using an encoding mode are provided. An encoding apparatus may select an encoding mode of a frame included in an input speech signal, and encode a frame having an unvoiced mode for an unvoiced speech as the selected encoding mode.
摘要:
An apparatus for encoding/decoding a multichannel signal. The apparatus for encoding/decoding a multichannel signal processes phase parameters for phase information among a plurality of channels constituting the multichannel signal in consideration of the characteristics of the multichannel signal. The apparatus generates an encoded bit stream for the multichannel signal using the processed phase parameters and the mono signal extracted from the multichannel signal.
