wavelet

This is the same sound transformed by a different type of wavelet.

这是用上幅图中同样的声音信号经过另外一种形式的小波变换而形成的声图。

It is then subject to such mathematical indignities as wavelet decomposition, multi-resolution Fourier analysis, polyphase filtering and discrete cosine transformation.

接下来它还要经过一些数学处理程序，比如小波分解，多重分辨率傅立叶分析，多相过滤，离散余弦变换等。

This is the same sound as led to the previous image, but Fischer has chosen a different type of wavelet to perform the transform and has played around with the result to produce a floral effect.

这是上幅图中同样的声音信号形成的声图，但是菲舍尔用了另外一种不同形式的小波进行变换，而且在声图上玩了一些花样，得到了这样花朵锦簇的效果。
