Audio signal record format applicable to memory chips and the reproducing method and apparatus therefor

摘要

An audio signal record format includes a first region for recording an audio signal having an accompaniment signal recorded in accordance with musical instrument digital interface (MIDI) format and having a first determination bit, and for recording a digitized vocal signal including a second determination bit, and a second region for recording index information with respect to the recorded audio signal. The first and second determination bits permit separation of the accompaniment and vocal signals during simultaneous readout thereof so as to facilitate production of analog signals and decoding, respectively. The record format is compatible with integrated circuit memories. A method employing the record format and a corresponding player are also described.
