<p>PURPOSE:To surely detect the interval of music with a simple constitution by detecting and using inter-music information included in a subcode at the time of recording a digital audio signal. CONSTITUTION:Subcode data is outputted together with a digital audio signal from a CD player which regenerates the audio signal recorded with a digital signal, and inter-music information is obtained from a P code, which is included in the subcode and indicates the intervals of music, in a digital sound recorder (DAT recorder) where sound are recorded in a form of digital signal. The subcode is decoded to detect the intervals of music in such a manner. Thus, the intervals of music are surely detected with the simple constitution.</p> |
