setenv: Set the amplitude envelope of a time wave to another one

Description

This function sets the amplitude envelope of a time wave to another one

Usage

setenv(wave1, wave2, f, envt="hil", msmooth = NULL, ksmooth = NULL,
plot = FALSE, listen = FALSE, output = "matrix", ...)

Value

• If plot is FALSE, a new wave is returned. The class of the returned object is set with the argument output.

Details

wave1 and wave2 can have different duration (length) Smoothing the envelope with smooth or ksmooth can significantly change the value returned.

Examples

data(tico)
a<-synth(d=1,f=22050,cf=1000)
# apply 'tico' ammplitude envelope to 'a' that has a square amplitude envelope
setenv(a,tico,f=22050,plot=TRUE)
# the same but with smoothing the envelope
setenv(a,tico,f=22050,ksmooth=kernel("daniell",50),plot=TRUE)
