writeWave: Writing Wave files

In tlevine/tuneR: Analysis of music and speech

Description

Writing Wave files.

Usage

writeWave(object, filename, extensible = TRUE)

Arguments

object	Object of class Wave or WaveMC to be written to a Wave file.
filename	Filename of the file to be written.
extensible	If TRUE (default), an extensible Wave format file is written. If FALSE, a non-extensible Wave file is written.

Details

It is only possible to write a non-extensible Wave format file for objects of class Wave or for objects of class WaveMC with one or two channels (mono or stereo).

If the argument object is a Wave-class object, the channels are automatically chosen to be “FL” (for mono) or “FL” and “FR” (for stereo).

The channel mask used to arrange the channel ordering in multi channel Wave files is written according to Microsoft standards as given in the data frame MCnames containing the first 18 standard channels.

The function normalize can be used to transform and rescale data to an appropriate amplitude range for various Wave file formats (either pcm with 8-, 16-, 24- or 32-bit or IEEE_FLOAT with 32- or 64-bit).

Value

writeWave creates a Wave file, but returns nothing.
