摘要：
A method for determining a number of bits for encoding an audio signal comprising a core audio signal portion and a residual audio signal portion is described that comprises selecting, from the residual audio signal portion, a reference residual audio signal portion and at least one candidate residual audio signal portion; comparing the reference residual audio signal portion with the candidate residual audio signal portion; and determining the number of bits for encoding the audio signal depending on the result of the comparison.
摘要（中）：
一种用于确定用于编码包括核心音频信号部分和残余音频信号部分的音频信号的比特数的方法，其包括从残留音频信号部分中选择参考残差音频信号部分和至少一个候选残差 音频信号部分; 将所述参考残差音频信号部分与所述候选残留音频信号部分进行比较; 以及根据比较结果确定用于编码音频信号的比特数。
