savewav: Save a .wav file

Description

Save sound data as .wav file

Usage

savewav(wave, f, channel = 1, filename = NULL, rescale = NULL, ...)

Arguments

wave

an R object.

f

sampling frequency of wave (in Hz). Does not need to be specified if embedded in wave.

channel

channel of the R object, by default left channel (1).

filename

name of the new file. (by default the name of wave).

rescale

a numeric vector of length 2 giving the lower (negative value) and upper (positive value) amplitude limits of the .wav file to be exported.

...

other arguments to be passed to writeWave

.

Author

Jerome Sueur , Ethan C. Brown for the argument 'rescale'

Details

This function uses three functions from the package tuneR: Wave, normalize and writeWave.

Examples

require(tuneR)
a<-synth(f=8000,d=2,cf=2000,plot=FALSE)
# the name of the file is automatically the name of the object
# here: "a.wav"
savewav(a,f=22050)
unlink("a.wav")
# if you wish to change the name, use the 'file' argument
savewav(a,f=22050,file="b.wav")
unlink("b.wav")
# if you wish to change the amplitude of the file, use the argument 'rescale'
# this will turn down the volume of a 16 bit sound
# which amplitude was originally ranging between -2^15 and +2^15
savewav(a, f=22050, file="c.wav", rescale=c(-1500,1500))
unlink("c.wav")
