MP3作为Internet上最流行的音乐格式,已经得到了广大音乐爱好者的青睐。它利用MPEG Audio Layer3的技术,以44.1KHz频率立体声取样的数码音频加以编码压缩的档案格式。MP3的压缩比例可高达1∶10至1∶12,相当于以128Kbps至112Kbps的位元速率传送立体声信号。因此,一张70分钟的CD,经过压缩制作成MP3格式的音乐,可以存放70多首歌,且人耳觉察不出音质的损失,这真正地作到了价廉物美,怎么不令音乐爱好者心动。
MP3 as the Internet’s most popular music format, has been the majority of music lovers of all ages. It uses MPEG Audio Layer3 technology to encode compressed file formats with digital audio sampled at 44.1 kHz stereo. MP3’s compression ratio can be as high as 1:10 to 1:12, which translates to stereo signals at bit rates of 128Kbps to 112Kbps. Therefore, a 70-minute CD, compressed to make MP3 format music, can store more than 70 songs, and the human ear can not detect the loss of quality, which really made cheap, why not make music lovers Heartbeat.
