Abstract:
Paper proposes optimization of calculation of frequency masking of speech signal for use in real time applications. The complexity of circular convolution is shown for iterative Toom-Cook algorithm with length 4 and an algorithm based on the FFT. The conclusion about the efficiency of the proposed solutions is drawn on computation complexity and memory.
Keywords:speech signal, frequency masking, circular convolution, optimization.
