针对语音信号或音频信号的量化方法以及解码方法和设备
Abstract:
提供了一种针对语音信号或音频信号的量化方法以及解码方法和设备。提供了一种量化设备，包括：量化路径确定器，在输入信号的量化之前，基于标准从包括不使用帧间预测的第一路径和使用帧间预测的第二路径确定路径作为输入信号的量化路径；第一量化器，如果第一路径被确定为输入信号的量化路径，则对输入信号进行量化；第二量化器，如果第二路径被确定为输入信号的量化路径，则对输入信号进行量化。
Abstract(English):

A quantizing apparatus is provided that includes a quantization path determiner that determines a path from a first path not using inter-frame prediction and a second path using the inter-frame prediction, as a quantization path of an input signal, based on a criterion before quantization of the input signal; a first quantizer that quantizes the input signal, if the first path is determined as the quantization path of the input signal; and a second quantizer that quantizes the input signal, if the second path is determined as the quantization path of the input signal.
