USER'S TASTE COMPENSATION TYPE IN PSYCHOLOGICAL SOUND MODEL

摘要

Disclosed is a psychology acoustic model for compensation of user's appetite within a high definition television(HDTV) or a digital audio compressor. The model comprises a maximum value detector(21), a frequency analyzer(22), an user's appetite applier(25), a frequency distribution deformer(26), a hearing characteristic applier(23) and a bit assigner(24). The user's appetite applier(25) outputs a frequency distribution deforming coefficient according to an user's appetite input. The frequency distribution deformer(26) processes the audio signal whose frequency is according to the frequency distribution deforming coefficient. Thereby, the voice signal can be coded according to the user's individual appetite.
