Witrynaﬁlterbank. In contrast to a common gammatone ﬁlterbank, our ﬁl-ters are restricted to 2 ms length to allow for low-latency process-ing. Inspired by the encoder learned by Conv-TasNet, in addition to the logarithmically spaced ﬁlters, the proposed ﬁlterbank holds mul-tiple gammatone ﬁlters at the same center frequency with varying WitrynaThe algorithm is an implementation of an idea proposed in [2]. The design of the gammatone filter bank can be described in two parts: the filter shape (gammatone) …
