From the implementation of sincnet - there are 3 matmul functions (calculate low band, high band and conv1D)
For out_channel = 80, Filter_len=401, Input length = 24567 for 1.5s audio
Low & high band = 280401 ops (negligible) Conv1D = out_channelfilter_leninput_size = 788M or 525MOps/s
But is this calculation correct? It seems too high when sincnet was supposed to be more optimized.
