ABSTRACT:
A lyrics adapter allows a standard cassette player to play tapes for karaoke that contain the lyrics to the music and timing data associated therewith that are recorded as audio tones on the tape. The adapter detects silent periods greater than a predetermined length on the audio signals from the cassette player and converts the subsequent audio tones into a digital signal. When an end of message (EOM) code is detected, the adapter connects the audio signals containing music to external speakers. As the music plays, a central processing unit (CPU) calculates the elapsed time from the EOM code and transfers the data corresponding to the lyrics that are to displayed at that time thereby displaying the lyrics in real time and in synchronization with the music as it is being played.
