comb~
Apply a comb filter effect
Description
Use the comb~ object to apply the classic comb filtering effect to an audio input. The comb~ object mixes the current input sample with earlier input and/or output samples, according to the formula:
yn = axn + bxn-(DR/1000) + cyn-(DR/1000)
where R is the sampling rate and D is a delay time in milliseconds.
Arguments
delayTime [auto]
Sets the delay time in ms.
gain [auto]
Sets the filter gain.
ffGain [auto]
The feedforward coefficient.
fbGain [auto]
The feedback coefficient.
Inlets
x [auto]
The signal to be filtered.
delayTime [auto]
Sets the delay time in ms.
gain [auto]
Sets the filter gain.
ffGain [auto]
The feedforward coefficient.
fbGain [auto]
The feedback coefficient.
Outlets
out1 [signal]
The filtered signal.
Dynamic Attributes
These attributes can be modified in the code during execution using the set object
delayTime [auto]
Sets the delay time in ms.
fbGain [auto]
The feedback coefficient.
ffGain [auto]
The feedforward coefficient.
gain [auto]
Sets the filter gain.
reset [bang] (default: 0)
Banging this attribute will reset the object to its default state.
x [auto]
The signal to be filtered.
