Usage

 blurr [-sn struct<integer> | 
        -s struct<string> | 
        -sb struct<string> | 
        -cf centre frequency<real>]
       [-sf gaussian window factor<real>]

-s

Filter structure string, defined as a quad tree. See the module filtertree (CompileFiltStructTree) for a description of the structure.

-sb

Filterstructure string, defined as a binary tree. See the module filtertree (CompileFiltStructTreeFromBin) for a description of the structure.

-sn

Filter structure number, between 1 and 11 (default 4). See the module filtertree (BuildFiltStructTree) for a description of the structure.

-cf

Centre frequency which to tune the Gaussian lowpass filter to. Refer to Farshid Farrokhnia's Ph. D. dissertation for a description of the relationship between centre frequency and gaussian lowpass filter.

-d

Blurr a critically sampled filter output, as created by qmf -d .
