sound - sound player facility
sound(y,fs) sends the signal in vector y (with sample frequency fs) out to the speaker. Values in y are assumed to be in the range -1.0 <= y <= 1.0. Values outside that range are ugnored. Stereo sounds are played, on platforms that support it, when y is an N-by-2 matrix. sound(y) plays the sound at the default sample rate of 8192 Hz. sound(y,fs,nbits) plays the sound using nbits bits/sample if possible. Most platforms support bits=8 or 16.
