class:: WaveletDaub
summary:: decomposition into Daub4 wavelets, and reconstruction
related:: Classes/WalshHadamard
categories:: UGens>Analysis
Description::
Wavelet transform using the Daub4 basis.
The plug-in demonstrates the transform in the context of a filter; choose how many of the strong::n:: basis elements to use in the reconstruction.
Classmethods::
method::ar
argument::input
Original signal to effect
argument::n
size of wavelet transform. Must be divisible by 64, the standard blocksize.
argument::which
Basis elements whose indices are below this number will be zeroed. The default 0 means the identity transform, all basis elements will be used in the reconstruction.
Examples::
code::
{var n= 1024; WaveletDaub.ar(SoundIn.ar, n, MouseX.kr(0,n))}.play
{var n= 1024; WaveletDaub.ar(Saw.ar(MouseY.kr(50,10000, 'exponential'),0.5), n, MouseX.kr(0,n))}.play
