摘要： A signal processing apparatus and method thereof are disclosed. The present invention includes receiving a low frequency downmix signal including a multi channel signal, phase shift information and spatial information corresponding to parameter band of the low frequency downmix signal, generating the multi channel signal by applying the spatial information based on the parameter band to a whole frequency downmix signal, generating estimated phase shift information of a parameter band by using the phase shift information, and generating a phase shift multi channel signal by shifting a phase of the multi channel signal based on the phase shift information and the estimated phase shift information. Accordingly, it is able to efficiently reproduce a phase or delay difference, which is difficult to be efficiently reproduced by a decorrelator, in a manner of shifting a phase of a decoded audio or speech signal based on phase shift information. And, a phase shift is enabled to fit each parameter band of a multi channel signal with raised coding efficiency.
