摘要： Disclosed are an apparatus and a method for separating sound sources capable of learning distributions of corresponding sound sources based on the assumption that specific sound sources have specific distributions based on interchannel correlation parameter in audio signals providing space perception through a plurality of channels to separate an amount corresponding to energy contribution of the corresponding sound sources from mixture signals. Exemplary embodiments of the present invention can more precisely predict the channel distributions of the specific sound sources included in the input mixture signals and more accurately separate sound sources than a method for separating a sound source based on the channel according to the related art, under conditions that general channel distribution information of the specific sound sources are approximately modeled.

摘要： A method for compressing and decompressing a multi-channel signal using virtual source location information (VSLI) on a semicircular plane is provided. VSLI, rather than inter channel level difference (ICLD), is used as spatial cue information, thereby minimizing loss caused by quantization of spatial cue information, improving sound quality of a decompressed audio signal, and reproducing an excellent audio signal by reducing distortion upon decompression of an original signal at a decoder spectrum.
