MP3是一种数字音频格式,MP3是技术术语MPEG-1AudioLayer-3的缩写,就是动态影像压缩处理小组的意思。MP3由于采用了高比率的数字压缩技术(压缩比率可达到12:1),经过MP3编码软件进行编码后,容量为640MB的普通CD盘(就是你买的MP3音乐光盘)就能存储十几个小时的声音文件,每分钟声音的MP3文件只有1MB左右大小,这样每首歌的大小只有数兆字节。然后使用MP3播放工具对MP3文件进行实时的解压缩(解码),把还原后的声音信号输出到扬声器上,高品质的MP3声音就播放出来了。
MP3 is a digital audio format, MP3 is the abbreviation of the technical term MPEG-1AudioLayer-3, is the meaning of the dynamic image compression processing group. MP3 as a result of a high rate of digital compression technology (compression ratio up to 12: 1), encoded by the MP3 encoding software, the capacity of 640MB ordinary CD (you buy MP3 music CD) can store a dozen Hour audio files, MP3 files per minute sound only about 1MB size, so that the size of each song is only a few megabytes. Then use the MP3 player tool for real-time decompression MP3 files (decoding), the restored sound signal output to the speaker, high-quality MP3 sound to play out.
