readWave: Reading Wave files

Description

Reading Wave files.

Usage

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

Value

An object of class Wave or WaveMC

or a list containing just the header information if header = TRUE. If the latter, some experimental support for reading bext chunks in Broadcast Wave Format files is implemented, and the content is returned as an unprocessed string (character).

Arguments

filename: Filename of the file to be read.
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.
toWaveMC: If TRUE, a WaveMC-class object is returned. If NULL (default) or FALSE and a non-extensible Wave file or an extensible Wave file with no other than the “FL” and “FR” channels is found, a Wave-class object is returned, otherwise a WaveMC-class object.

Examples

Run this code

Wobj <- sine(440)

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