Abstract: A binaural decoder for an MPEG surround stream, which decodes an MPEG surround stream into a stereo 3D signal, and a decoding method thereof. The method includes dividing a compressed audio stream and head related transfer function (HRTF) data into subbands, selecting predetermined subbands of the HRTF data divided into subbands and filtering the HRTF data to obtain the selected subbands, decoding the audio stream divided into subbands into a stream of multi-channel audio data with respect to subbands according to spatial additional information, and binaural-synthesizing the HRTF data of the selected subbands with the multi-channel audio data of corresponding subbands

Abstract: An audio correction apparatus and an audio correction method. The audio correction method includes: receiving audio data, which may be input by a user and/or an instrument uttering sounds; detecting onset information by analyzing harmonic components of the received audio data; detecting pitch information of the received audio data based on the detected onset information; comparing the audio data with reference audio data and aligning the two based on the detected onset information and the detected pitch information; and correcting the aligned audio data to match the reference audio data.
