The quality of digital audio is characterized by the sampling rate, the quantization interval and the number of channels 数字音频的质量可以用抽样频率、量化电平和声道数来表征。
The quantization interval, or the difference in value between two adjacent quantization levels, is a function of the number of bits per sample and determines the dynamic range 量化阶距,即两个相邻的量化电平之间的差值,是每个抽样的比特数的函数,它决定了动态范围。
