ENCODING APPARATUS AND METHOD FOR ENCODING SOUND CODE, DECODING APPARATUS AND METHDO FOR DECODING THE SOUND CODE

摘要

A decoding device comprises: a sound code input unit which receives a sound code outputted from an encoding device through a sound wave receiving device; a frame division unit which divides the sound code into a plurality of frames according to predetermined time intervals; a frequency identification unit which identifies a frequency which corresponds to each frame through frequency analysis for each frame; and an information generation unit which generates information which corresponds to the sound code based on part information which corresponds to each identified frequency.
