Abstract

The present invention relates to a method for generating and playing a music file and a computer-readable recording medium carrying the music file, which records all events executed at the same time in individual event fields and corresponds to A single time field makes the music file have a smaller file length. When reading the music file, read the time field and one or more corresponding event fields.

Description

technical field [0001] The present invention relates to a method for generating music files, especially a method for using the time field and event field format of the digital interface of the Music Association as the method for generating the time field and event field of music files, and the music file The playback method and the computer-readable recording medium containing the music file. Background technique [0002] In the field of playing music, MIDI (Music Instrument Digital Interface) music file format has always been a very popular standard. Among them, the MIDI music file format can be divided into SMF (Standard Music Association Digital Interface Format, standardMIDI format) and SMAF (Synthetic music mobile application format, Synthetic music Mobile Application Format). As shown in Figure 1, the SMF area is divided into three parts: one is the time field 11, which is used to record the corresponding time; the other is the status field 12, which is used to record...
