数字音频压缩（ＡＣ－３）（五）（摘译）７．２比特指派７．２．１概述比特指派程序对在进行编码的音频信号，从掩盖效应分析它的频谱包络，以确定将需要的比特数分派给各变换系数的尾数。在编码器中，把所有声道作为一个整体，从一个公共比特区对它实行总的比特指派，没... Digital Audio Compression (AC-3) (V) (Excerpt) 7.2 Bit Assignment 7.2.1 Overview The bit assignment procedure analyzes the spectral envelope of the audio signal undergoing encoding from the masking effect to determine whether the The number of bits required is assigned to the mantissa of each transform coefficient. In the encoder, all the channels as a whole, from a common bit area to the implementation of its total bit assignment, no ...
