[R] Playing a music file in R

Hello vahid.borji,

Wave files, and probably a few other formata, can be loaded, saved and manupulated with (a.o.)  these packages:

library(signal)  
library(seewave)
library(tuneR)


In addition, to play a wave file, a small Unix file is necessary, called "play".
It must be attached by the following line:

	setWavPlayer("/Library/Frameworks/R.framework/Versions/3.6/Resources/bin/play")   # path depends on your R version etc.


Then, a simple script like the following will do:


	inname = file.choose()
	ywave=readWave(inname)
	ster=ywave using stereo
	srate=ywave using samp.rate
	play(ywave)


Hoping this helps, I remain
With best regards,
