Description: 观测实时模拟信号（语音）的频谱
用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图。

Description: Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1] or [2] for more detail about the algorithm.

Description: Udo Zolzer2002年编写的《Digital Audio Effects》，由Jonh Wiley & Sons公司出版。
作者从应用工程师的角度阐述数字音效处理技术，用大量图片代替了枯燥的公式推导，是一本难得的音频工程应用参考书。这本书的第二版也已于2008年出版，名字为<Digital Audio Signal Processing>。-A fully updated second edition of the excellent Digital Audio Signal Processing
Well established in the consumer electronics industry, Digital Audio Signal Processing (DASP) techniques are used in audio CD, computer music and multi–media components. In addition, the applications afforded by this versatile technology now range from real–time signal processing to room simulation.
Digital Audio Signal Processing, Second Edition covers the latest signal processing algorithms for audio processing. Every chapter has been completely revised with an easy to understand introduction into the basics and exercises have been included for self testing. Additional Matlab files and Java Applets have been provided on an accompanying website, which support the book by easy to access application examples.
