vibr — Easier-to-use user-controllable vibrato.


Easier-to-use user-controllable vibrato.


kout vibr kAverageAmp, kAverageFreq, ifn


ifn -- Number of vibrato table. It normally contains a sine or a triangle wave.


kAverageAmp -- Average amplitude value of vibrato

kAverageFreq -- Average frequency value of vibrato (in cps)

vibr is an easier-to-use version of vibrato. It has the same generation-engine of vibrato, but the parameters corresponding to missing input arguments are hard-coded to default values.


Here is an example of the vibr opcode. It uses the file vibr.csd.
