一个使用数学方法生成波形声音文件的源代码，可以载入预置数学公式，保存8位和16位单声道声音文件，可以设置振幅、频率、持续、采样等参数，可以调整波形斜面，回声。-Using mathematical method to generate a waveform audio file of the source code, you can load the preset mathematical formula holds the 8-bit and 16-bit mono sound file, y

TSSI positive slope, 1: positive, 0: negative u8 tssipos .

BOCU-1 encodes the code points of a Unicode string as a sequence of byte-encoded differences (slope detection), preserving lexical order.

Code, there are very complete notes and explanations Including Deng's correlation, absolute correlation, correlation of slope, improved absolute correlation, Conducted through virtual array DOA estimation.

Maximum Likelihood (ML) criteria and maximum a posteriori (MAP) criterion, Including orbital maneuvering simulation, initial orbit calculation, Including Deng's correlation, absolute correlation, correlation of slope, improved absolute correlation.
