shcodec ver 1.0.1 - a fast and efficient Huffman coder. Using only 1280 bytes to 574 bytes of encoding and decoding is very fast. shcodec use an effective method for packaging the code tree and can easily be integrated with your program. This package

1280点fft变换，改变传统的需2046点FFT的情况。-1280 point FFT，radix 4 and radix 5

傅里叶级数变化，进行信号的分析预处理，同时完成基本的傅里叶变化，对信号处理有很多作用-Fourier series change, the analysis of the signal preprocessing, while completing the basic Fourier transform, there are many effects on signal processing
