nd then records the remaining information in an efficient manner. 樣例文本 B ? The use in MP3 of a lossy pression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original unpressed audio for most listeners. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11 the size[note 1] than the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality. ? The pression works by reducing accuracy of certain parts of sound that are considered to be beyond the auditory resolution ability of most people. This method is monly referred to as perceptual coding.[13] It uses psychoacoustic models to discard or reduce precision of ponents less audible to h
