ABSTRACT:
Components include: an audio input, an audio output, a signal processor, a buffer memory, an interface, a command input, a display, and a controller. When a record command is input, the controller detects a non-sound section of the audio signal input, generates time data corresponding to the non-sound section, forms a data transmission block using the time data and sound data, records the result into an IC memory card, and registers a list of the newly recorded content at a content table. When a reproduction command is input, the controller reads the start/end address of a selected musical piece with reference to the TOC which is loaded into the buffer memory from the IC memory card, accesses the corresponding audio data from the IC memory card, and controls the system according to a reproduction operation. Silence sections are only stored at the beginning of a musical piece.
