This Java ME application demonstrates the use case of downscaling and upscaling the UI to different types of devices and using touch and keyboard events in the same application. UX design and graphics have been ported from the Sudokumaster Flas

变采样和多相滤波器的实现。本程序实现了一个变采样程序，中间设计滤波器设计和插值抽取。其中滤波器设计用的是窗函数法，根据要求设计窗函数，得到窗函数的长度。接着是插值，滤波，抽取，得到最后变采样之后的波形文件、另外对比了用直接卷积和多相分解卷积两种方法最后的结果。 -Implementation of variable sampling and polyphase filter. This procedure implements a variable sampling procedures,

零延时卷积算法实现，基于fft变换。Efficient Convolution Without Latency by William G. Gardner-It is well known that a block FFT implementation of convolution is vastly more efficient than the direct form FIR filter. Unfortunately, block processing incurs signifi
