音频

The third audio signal is convolution of the first audio signal and the environment channel impulse response.

第三音频信号为第一音频信号与环境信道脉冲响应的回旋积分。

Experimental results show that the two schemes can preserve inaudibility and they are robust enough to against the different signal processing operations. In addition, very large watermarking information can be embedded into the original audio signal. Furthermore, it can resist the cropping and MP3 compression attacks.

仿真实验结果表明，两种算法都具有较强的鲁棒性和不可感知性，水印嵌入容量大，提取水印时不需要原始音频信号的参与，并且对裁剪、时间伸缩等攻击具有较强的稳健性，是可行的数字音频水印算法。

Thefrequency analysis of the psychoacoustic model can give the inaudible, redundanelements of audio. In this paPer we employ it to gUarantee the inaudibility of theembedded watermark.

心理声学模型的时频域分析主要用于音频数据的压缩编码，这里主要考虑将其用于音频水印算法中去，以便从理论的角度来考虑嵌入水印的不可感知性。

The experimental results show the two practical algorithms can preserve inaudibility and they are robust enough to against the different signal processing operations. In addition, the watermarking information can be embedded into the original audio signal adaptively, which also doesnt require the use of the original audio signal for detection. Furthermore, it can resist the different attacks, such as lossy compression (MP3), filtering, resampling and requantizing, etc.

仿真实验结果表明，两种方法都具有较强的鲁棒性和不可感知性，水印嵌入容量的自适应性，提取水印时不需要原始音频信号的参与，且对包括MP3有损压缩、低通滤波、重采样/重量化等多种攻击性试验具有较强的稳健性，是可行的数字音频水印算法。

But realization of inaudibility for audios is much more difficult than realizing invisibility for images, the reason for this is that audio signals are represented by much less samples per time interval compared with images and video.

但是由于人耳听觉系统(Human Auditory System，简称HAS)比人眼视觉系统(Human Visual System，简称HVS)灵敏、以及音频作品的采样点数较少等缘故，使得音频数字水印实现不可感知性比较困难。

It builds audio cutter and audio joiner in one software.

它建立的音频刀具和音频joiner在一个软件。

According to our analysis, except for Ladd's 'overall' tone raising, there should also be 'partial' tone raising.

在我们的语料中，除了音频整体上扬，我们还观察到音频有时也会有部份上扬的情形。

There is provided a playback method for decode-processing and playing back coded audio data which is transmitted with necessary stereo process information required for a stereo process intermittently multiplexed into coded information of a monaural audio signal.

本发明提供了一种再生方法和设备，用于对与立体声处理所需的被间歇复用在非立体声音频信号的编码信息中的立体声处理必需信息一起传输的编码音频数据进行解码处理和再生。

Good power distribution system is essential to the proper operation of the audio system. Professional audio systems just don′t work well with normal extension cords running hundreds of feet to a stage.

优良的电源分类连接系统是音频系统正确实施的基本要点，专业音频系统最好不要与其他设备一起使用同一个电源。

Audio processing support - built in DirectSound, basic audio processing (preamp, remove left/right channel, channel swap etc.), advanced video processor equalizer, echo, pitch, normalizer, true bass, treble etc.

音频处理支持-建于D irectSound的，基本的音频处理（前置，排除左/右通道，通道互换等），先进的视频处理器（均衡器，回声，音调，正规化，真正的低音，高音等

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
