sound player facility
real number, sampling frequency in sample per second (default value is 22050)
real number, number of bits (unused)
Only used on Unix systems it gives the name of the command to use for playing sound (wav) files. The default value is
aplay. If set
/dev/audiothen a 8 bits mu-law raw sound file is created and send to
sound(y,fs)plays the sound signal given by matrix
y (with sample frequency
fs). In fact this function is just a wrapper for
playsnd. Values in y are assumed to be in the
range -1.0 <= y <= 1.0. Values outside that range are truncated.
The number of rows of
y gives the number of channels.
sound(y) plays the sound at the default sample rate of 22050 sample per second.
sound(y,fs,nbits) plays the sound using
nbits bits/sample if
possible (it is in fact unused). Most platforms support bits=8 or 16.
// a two channel signal y=loadwave("SCI/modules/sound/demos/chimes.wav"); sound(y)
