WaveIO: Reading and writing Wave files

Description

Reading and writing Wave files.

Usage

readWave(filename, from = 1, to = Inf, 
    units = c("samples", "seconds", "minutes", "hours"), header = FALSE)
writeWave(object, filename)

Arguments

filename

Filename of the file to be read or written.

from

where to start reading (in order to save memory by reading wave file piecewise), in units.

to

where to stop reading (in order to save memory by reading wave file piecewise), in units.

units

units in which from and to is given, the default is samples, but can be set to time intervals such as seconds, see the Usage Section above.

header

if TRUE, just header information of the Wave file are returned, otherwise (the default) the whole Wave object.

object

Wobj <- sine(440, bit = 16)

tdir <- tempdir()
tfile <- file.path(tdir, "myWave.wav")
writeWave(Wobj, filename = tfile)
list.files(tdir, pattern = "\.wav$")
newWobj <- readWave(tfile)
newWobj
file.remove(tfile)
