vibr

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

Description

Easier-to-use user-controllable vibrato.

Syntax

kout vibr kAverageAmp, kAverageFreq, ifn

Initialization

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

Performance

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.

Examples

Here is an example of the vibr opcode. It uses the files vibr.orc and vibr.sco.
