Description: 该代码仅计算了一个101×101尺寸的Gabor函数变换，得到均值和方差。代码采用两种卷积计算方式，从结果中可以看出，快速傅立叶变换卷积的效率是离散二维叠加和卷积的近50倍。
-The code is only the calculation of a 101 × 101 size Gabor function transformation, the mean and variance. Convolutional code using two methods of calculation can be seen from the results, fast Fourier transform convolution efficiency are two-dimensional discrete convolution superposition and nearly 50 times.

Description: Frequency Analyzer.
Whistle a melody and watch this program graph the pitch in real time. The Frequency Analyzer (download now) technically speaking performs a Fast Fourier Transform of the sound (you need a sound card and a microphone to use this program). What it means is that it analyzes your voice and splits it into its component frequencies. Watch patterns of speech, the harmonics of vowels and the noise of sibilants. The size of the program is only 148k! (zipped 74k) Can you believe that?! There are web pages that make you download more than that just to be able to look at them. Platform: |

Description: 吉他调弦，相当于ap guitar tuner-This article shows how to use a Fast Fourier Transform (FFT) algorithm to calculate the fundamental frequency of a captured audio sound. Also, we will see how to apply the algorithm to analyze live sound to build a simple guitar tuner: the code provides a solution to the problem of calculation of the fundamental frequency of the played pitch.
