摘要

The player/recorder has an electronic interface to transmit/receive digital data, where output level of a signal source is indirectly measured by a measurement of a preamplification degree required to process signal, while recording. Measured value is digitalized together with the signals and stored in a folder. Comments are entered in text form to the source to process digital data, and are recorded with digital audio signal.
