In this study, we propose a new type of complex wavelet, named Motion Wavelet. The shape of the Motion Wavelet is changed according to a certain reference signal, and its variable wavelet transforms another target signal, which is therefore picked out the variable frequency elements according to the reference signal. These relational transforms can be applied to making new entertainment sounds. For example, if we adopt a voice of a speaking as the reference signal and many kind of signals -such as cries of animals, sounds of musical instruments and other nature sounds- as the target signal, we can get interesting and illusionary entertainment sounds which sound as if the animals spoke human words, the musical instruments sang a song and so on.
