Description: FFT and IFFT for 16-bits wave, you can
use this instead of convolution calculate, input samples must be 2^n.
If its not 2^n samples just stuff zero
in last array.
I already make it to C++ class you can
new a calss and do it easy,FFT and IFFT for 16-bits wave, you can use this instead of convolution calculate, input samples must be 2 ^ n.If its not 2 ^ n samples just stuff zeroin last array.I already make it to C++ Class you cannew a calss and do it easy Platform: |

Description: 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. Platform: |
