Wavelet transform using the Daub4 basis.
The plug-in demonstrates the transform in the context of a filter; choose how many of the n basis elements to use in the reconstruction.
Original signal to effect
size of wavelet transform. Must be divisible by 64, the standard blocksize.
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.
