System and method of extracting supplement information from acoustic signal

The present invention relates to a system and method for extracting to extract the additional information from the sound signals, the system to insert the additional information in accordance with the present invention divides the sound signal into the frame divided, the sub-frame to the frame divided into a plurality of frames to sub-frame divided, the Fourier transform unit for the Fourier transform for each sub-frame, the Fourier-transformed sub-band division, the additional information for the plurality of subbands for the acoustic signal for dividing the sub-frame to sub-band music, audio books and having a insertion to insert by adjusting the energy of the telephone calls, the speaker of the street, and various public transport and public places, such as by passing by inserting the relevant additional information on the acoustic signal when all of the sound signal is transmitted by being extracted to obtain additional information by using the wireless device and the like from the sound signal output from it it is possible to enjoy the enhanced mobile.
