ABSTRACT:
An automatic timbre control method and apparatus detect a sub-code representing a music pattern from a signal reproduced from a compact disc, analyze the music pattern depending on the sub-code in a microcomputer, read out a timbre mode coefficient from a coefficient ROM table depending on the analyzed music pattern, and apply the timbre mode coefficient to a digital equalizer so that equalizing can be controlled automatically. Thus, users need not frequently operate an equalizer depending on the input music pattern, and are able to listen music with better timbre quality.
