MonoStereo: Converting (extracting, joining) stereo to mono and vice...

In tuneR: Analysis of music and speech

Description

Functions to extract a channel from a stereo Wave object, and to join channels of two monophonic Wave objects to a stereophonic one.

Usage

mono(object, which = c("left", "right", "both"))
stereo(left, right)

Arguments

object	Object of class Wave.
which	Character, indicating whether the “left” or “right” channel should be extracted, or whether “both” channels should be averaged.
left	Object of class Wave containing monophonic sound, to be used for the left channel.
right	Object of class Wave containing monophonic sound, to be used for the right channel (if missing, the left channel is duplicated). If right is missing, stereo returns whether left is stereo (TRUE) or mono (FALSE).

Details

For objects of WaveMC-class, a mono channel can be created by simple matrix indexing, e.g. WaveMCobject[,2] selects the second channel.

Value

An object of class Wave.

If argument right is missing in stereo, a logical values is returned that indicates whether left is stereo (TRUE) or mono (FALSE).
