PROBLEM TO BE SOLVED: To accurately monitor an arbitrary electric signal through hearing for a long time. SOLUTION: This system is equipped with a signal input means 10 which digitally inputs a time-series electric signal and generates a digital electric signal, an encoding means 14 which converts the digital electric signal into MIDI(musical instrument digital interface) codes and outputs them to a code sending-out means 12, a music storage means 16 which stores arbitrary music data in MIDI codes, a code modulating means 18 which modulates the MIDI codes stored in the music storage means 16 according to the digital signal and outputs the modulated codes to the code sending-out means 12, a system switching means 20 which performs ON/OFF control over the outputs to the encoding means 14 and the code sending-out means 12 of the code modulating means 18, and a receiving and decoding means 22 which receives the MIDI codes outputted from the code sending-out means 12 and reproduces music by using a MIDI sound source. |
