feed forward comb filter

available since version: 0.9.1

---

information

Frequency response of a comb filter consists of a series of regularly spaced notches, giving the appearance of a comb Structure of a feedforward comb filter may be described by the following difference equation: y[n] = x[n] + α[n−K] where K is the delay length (measured in samples), and α is a scaling factor applied to the delayed signal

arguments:

• A scaling factor of delayed signal
  type: float
  

methods:

• reset reset filter state
  

properties:

• @a Get/set scaling factor of delayed signal
  type: float
  range: -1..1
  default: 1
  

• @active Get/set on/off dsp processing
  type: bool
  default: 1
  

• @osc (initonly) Get/set OSC server name to listen
  type: symbol
  

• @id (initonly) Get/set OSC address id. If specified, bind all properties to /ID/flt_ff_comb/PROP_NAME osc address, if empty bind to /flt_ff_comb/PROP_NAME.
