Abstract: A method of encoding a multi-object audio signal and an encoding apparatus, a decoding method and a decoding apparatus, and a transcoding method and a transcoder are provided. A multi-object audio signal encoding apparatus may encode object signals obtained by excluding ForeGround Objects (FGOs) from a plurality of input object signals, and may encode the FGOs, thereby providing a listener with a satisfactory sound quality.

Abstract: Provided is a method and apparatus for encoding/decoding a multi-channel audio signal. The apparatus for encoding a multi-channel audio signal includes a frame converter for converting the multi-channel audio signal into a framed audio signal; means for downmixing the framed audio signal; means for encoding the downmixed audio signal; a source location information estimator for estimating source location information from the framed multi-channel audio signal; means for quantizing the estimated source location information; and means for multiplexing the encoded audio signal and the quantized source location information, to generate an encoded multi-channel audio signal.
