Fischer prefers to use a less common mathematical process known as the wavelet transformation , which represents the sound in terms of short , discrete components known as wavelets .
菲舍尔更喜欢一种比较不常用的数学方法小波变换,这种方法可以将声音分解成比较短的离散的小波成分。
But tensor product wavelets has a number of drawbacks .
张量积小波有其自身的缺点。
When a puff of wind ruffles the surface , wavelets disturb the surface and the reflections disappear .
一阵风掠过水面,微波打乱了水面,倒影也不见了。
Small trees in leaf begin to sway ; crested wavelets form on inland waters .
有叶的小树摇摆,内陆的水面有微波。
In essence , we need a way to change scale at various points , and scale is at the heart of wavelets .
