一、数字声频文件格式数字声频文件的格式很多,通常分为两大类:波形声频文件和MIDI(乐器数字接口)文件。波形声频文件指的是直接记录了原始真实声音信息的数据文件,它又进一步分为压缩格式与非压缩格式两类。常见的非压缩格式声频文件是Wave(波形)文件(*.wav)、Voice文件(*.VOC);常见的压缩格式声频文件有MP3文件、ReatAudio文件(*.ra/*.rm)、WMA文件等。而MIDI文件则是一种乐器演奏指令序列,相当于乐谱,因此又称
First, the digital audio file format Digital audio files in many formats, usually divided into two categories: waveform audio files and MIDI (Instrument Digital Interface) files. Wave audio file refers to the direct record of the original real voice information data files, it is further divided into two types of compression format and non-compression format. Common uncompressed audio files are Wave files (* .wav), Voice files (* .VOC), and common compressed audio files are MP3 files, ReatAudio files (* .ra / *. Rm), WMA Documents and so on. The MIDI file, on the other hand, is a sequence of instrumental instrumental commands, which is equivalent to the score, so it is also called
