Recorder, recording/reproducing music method, broadcast and instrumental ensemble system

Abstract

A user records a part of a piece of music performed on the composite audio system into and reproduces the performance from a floppy disc in ensemble with another part of the piece of music; while a compact disc player is producing an audio signal from audio data codes, the composite audio system produces event codes representative of local peaks in the audio signal for timing control, and stores these event codes together with event codes representative of note events and duration data codes in the floppy disc; while the composite audio system and compact disc player are reproducing the parts of the piece of music, the time intervals among the tones are prolonged and shrunk by using the event codes for timing control and actual local peaks so that the tones in one of the parts are produced synchronously with the tones of the other part.

Description

technical field [0001] The present invention relates to a recording and playback technology, and in particular to a recorder, a method for recording music, a player, a method for such music, and an overall system. Background technique [0002] Compact discs are popular with music lovers. Music is recorded on compact discs and reproduced by compact disc players. While the musician is playing the music, the pitch is converted to an analog audio signal from which discrete values ​​are sampled. The discrete values ​​are converted into binary values ​​which are stored in the optical disc in the form of digital codes from the beginning of the performance together with control data codes representing the passage of time. In the following explanations, the digital codes representing discrete values ​​and the control data codes representing the passage of time are referred to as "audio data code" and "time data code", respectively, and the term "disc dat...

AI Technical Summary

Problems solved by technology

However, the optical disc players currently on the market do not have any signal output port from which the time data code is output to the outside, nor any signal input port for receiving the duration data code.

Also, CD players and MIDI instruments don't have any software to control recording and playback based on another kind of time data
