ABSTRACT:
Signal-reproduction method and apparatus receive a code string formed by coding a frequency-axial spectral signal obtained by performing the spectral transformation of a time-axial acoustic-waveform signal, and decode the received code string. Subsequently, the method and apparatus reproduce the acoustic-waveform signal by extracting part of the spectral signal, and performing the reverse-spectral-transformation of the extracted part.
