Details

If abs(pan)<50, mixtures of the two channels of s are used for the left and the right channel of the returned Sample object, so that they appear closer to the center. For pan=0, both sounds are completely in the center.

If pan<0, the left and the right channel are interchanged afterwards.

See Also

mirror for pan=-50, left and right for access to single channels of the sample.

Examples

if (FALSE) {
s <- stereo(Sine(440,1),Sine(330,1))
play(s)
play(panorama(s,30))  # now right and left tones are closer to the center
play(panorama(s,10))  # now even closer
play(panorama(s,0))   # now both at the center, the same as setChannels(s,1)
play(panorama(s,-30)) # again wider, but both sides switched
play(panorama(s,-50)) # the same as mirror(s)
}
