Examples

if (FALSE) {
# Play an audio file:
data('speechEx', package = 'soundgen')
playme(speechEx, from = 1, to = 2)
playme('pathToMyAudio/audio.wav')

# Create and play a numeric vector:
f0_Hz = 440
sound = sin(2 * pi * f0_Hz * (1:16000) / 16000)
playme(sound, 16000)
playme(sound, 16000, from = .1, to = .5)  # play from 100 to 500 ms

# Set default player for the current R session
# "play" (SoX library, default on Linux)
options(soundgen.player = 'play')
# "afplay" (ALSA, default on MacOS)
options(soundgen.player = 'afplay')

options(soundgen.player = "C:\\Program Files\\VideoLAN\\VLC\\vlc.exe")
