1. a method for processing signals, comprising:

  • The signal of at least one receiving spatial information and comprise in the first signal and secondary signal, wherein, described spatial information comprises at least one in the differential information of channel sound (CLD), Channel Prediction Coefficient (CPC), Inter-channel Correlation information (ICC) and downward conversion gain information (DMG);

    Receiving mode information and modified logo information, described pattern information represents one in the first decoding scheme and the second decoding scheme, and described modified logo information indicates whether to revise described first signal;

    When described pattern information represents described first decoding scheme, described first decoding scheme is used to decode to described first signal;

    When described modified logo information instruction have modified described first signal, then obtain instruction for adjusting the amendment reconfiguration information of the value of the length of the window being applied to described first signal;

    The length of described window is adjusted by using described amendment reconfiguration information;

    By the length of the window of Use Adjustment, described first signal is decoded;

    When described pattern information represents described second decoding scheme, described second decoding scheme is used to decode to described secondary signal;

    Based on extend information determination expansion base signal, described expansion base signal is corresponding with the subregion of the signal of decoding;

    Generate the downward mixed frequency signal of expansion, the downward mixed frequency signal of described expansion has the bandwidth that when using described expansion base signal and described extend information by utilizing, m-expansion and extraction carry out reconstructed high frequency regional signal and expand,WhereinDescribed first decoding scheme corresponds to audio coding scheme, andDescribed second decoding scheme corresponds to speech decoding scheme.
