Examples

## NOT RUN
# data(tico)
# listen(tico,f=22050)
# listen(tico,f=22050,from=0.5,to=1.5)
# listen(noise(d=1,f=8000,Wave=TRUE))
## change f to play the sound a different speed
# data(sheep)
## normal
# listen(sheep,f=8000)
## two times faster
# listen(sheep,f=8000*2)
## two times slower
# listen(sheep,f=8000/2)
