摘要
We have already proposed a new type of wavelet, named the "motion wavelet", whose mother wavelet is varied according to a certain reference signal, and at the same time, transforms another target signal. The wavelet allows variable frequency elements to be picked out from the target signal according to the reference signal. This motion wavelet can also be applied to making entertainment sounds. However, it generates only monaural sound and its effect is simple. In this paper, we propose a new type of motion wavelet having double the modulation performance by the real and imaginary parts of its complex mother wavelet varied according to two different reference signals. Furthermore, we introduce a fast calculation method for it and one of its applications to entertainment sounds.
