AB  - A block FFT implementation of convolution is vastly more efficient than the direct form FIR filter. Unfortunately, block processing incurs significant input/output delay which is undesirable for real-time applications. A hybrid convolution method is proposed which combines direct form and block FFT processing. The result is a zero delay convolver that performs significantly better than direct form methods.
