- 转换图像文件程序(方形,为音乐的最高120x120像素)文件(*. WAV和噪音)。你可以看在音乐谱图隐藏的图像 - 过程被称为声音隐秘。 -Program converts image file (square shape, maximum 120x120 pixels) into music file (*.wav, noise). You can watch the hidden image in spectrogram of music- process called sound s
MATLAB
- 数字电子琴的功能 电子琴的每个音阶均对应一个特定频率的信号,通过调用数字信号发生器产生一系列指定的频率的声音,从而达到虚拟的电子琴的功能,界面中包含A、B、…、O共 15 个琴键,鼠标按下时即发声,松开时发声停止。 同时能够产生正弦波、方波、三角波等常见的波形的数字信号,并且提供了图形界面用于选择波形、频率、幅值与相位。能够根据用户指定的波形和参数产生相应的数字信号,然后将数字信号写入声卡的缓冲区,最后由声卡播放出相应的声音。 -Digital electronic keyboar

- 本文简要介绍了语音信号采集与分析的发展史以及语音信号的特征、采集与分析方法,并通过PC机录制自己的一段声音,运用Matlab进行仿真分析,最后加入噪声进行滤波处理,比较滤波前后的变化。-This paper introduces the voice signal acquisition and analysis of the history and characteristics of speech signals, sampling and analysis methods, and thro
soundsignal
- 将声音文件在时间轴上分割成几段,分别将段的秩序及某些段内的秩序颠倒,从而实现了对声音文件的加密。首先,先读取一个声音信号,对信号做1024点FFT变换,取完点之后,分成四个向量,四个向量组成一个矩阵,再对每一个向量进行转置,再重新整合,从而就实现了回密的过程。-Sound files on the timeline will be divided into paragraphs, each paragraph of the order and reversed the order of some

VirtualSound
- 用头相关传输函数卷积合成虚拟声的方法,我们将利用没有方位信息的单通道声音信号(可以是一段标准语音,也可以是音乐等其他类型的声音),通过信号处理的方法赋予其方位感。 人能听到声音是声音在空间中传播的结果,声音从声源到人耳鼓膜传播过程中发生了变化,这种变化可以看成是人双耳对声音的滤波作用,因此我们将声音从自由场传到鼓膜处的传输函数定义为头相关传输函数(HRTF, Head Related Transfer Function),其对应的时域响应称为头相关冲激响应(HRIR, Head Relat
