audio masking

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。

Simultaneous masking which is an important research content of psychoacoustic, have a wide range of applications in audio coding, speech enhancement and so on.

同时掩蔽是心理声学的重要研究内容，在音频压缩编码、语音增强等方面有着广泛的应用。

Audio signal was segmented into frames and the masking thresholds of all sub-bands were estimated by psychoacoustic analysis.

算法将音频信号分帧进行心理声学模型分析，估计频域中各子带的最小掩蔽阈值；

Based on human auditory model and audio masking effects, an audio digital watermarking algorithm based on wavelet and cepstrum transform is proposed.

结合人耳听觉模型，利用人耳掩蔽特性，提出了一种基于小波分解和复倒谱变换的音频数字水印算法。

An Audio Digital Watermarking Algorithm Based on Auditory Masking Effect

一种基于听觉掩蔽效应的音频数字水印算法

The watermark embedded in this algorithm is a significant binary image and adaptively embedded according to frequency masking threshold of audio signal. The watermark can be extracted by hypothesis test.

嵌入的水印为视觉可辨的二值图像，水印能根据音频信号的频域掩蔽阈值进行自适应调整，水印的提取采用假设检验的方法。
