Abstract

The present invention discloses an audio file export method and device, relating to the technical field of audio. The method comprises a step of periodically obtaining the tone data of the first audio file corresponding to a predetermined number of sampling points until all tone data of the first audio file is obtained, and a step of generating a second audio file with a predetermined format corresponding to the first audio file according to all tone data of the first audio file, wherein, the format of the first audio file is a musical instrument digital interface (MIDI) format. The time of exporting a music file by using a MIDI audio file can be shortened greatly, and the exporting efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to a method and device for exporting audio files. Background technique [0002] MIDI (Musical Instrument Digital Interface) is a digital interface for musical equipment. As a general communication protocol, the MIDI protocol can enable communication between electronic musical instruments and electronic musical instruments, electronic musical instruments and computers. What MIDI transmits is not a sound signal, but instructions such as notes and control parameters. It instructs the MIDI device what to do and how to do it, such as which note to play and how loud it is. Most modern music is synthesized using MIDI plus sound banks. [0003] In the prior art, the process of converting an audio file in MIDI format into music usually needs to obtain the data corresponding to each note in the MIDI audio file from the tone library, which is equivalent to playing the entire...
