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.
