In this paper we put forward a method to estimate the audio masking threshold.
本文提出了一种估计听觉掩蔽门限的算法。
Calculating masking threshold of every critical band by auditory masking model, then quantization steps are controlled by masking threshold and value of audio carrier of the embedding points.
依据听觉掩蔽模型计算每个临界频带的掩蔽阈值，再根据水印嵌入点处的掩蔽阈值和音频载体值的大小共同控制量化步长。
Because of considering the temporal masking effects to set up a threshold and the valid hop size of transient points, this method is very suitable for perceptual audio coding.
由于考虑了时域掩蔽效应来设置检测门限和有效瞬态点间隔，非常适用于感觉音频编码。
