  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 significant input/output latency which is undesirable for real-time applications. A hybrid method is proposed for doing convolution by combining direct form and block FFT processing. The result is a zero latency convolver that performs significantly better than direct form methods.)
