WAVPLAY WAVPLAY

Usage

Plays a linear PCM set of samples through the audio system.  This
function is only available if the portaudio library was available
when FreeMat was built.  The syntax for the command is one of:

   wavplay(y)
   wavplay(y,sampling_rate)
   wavplay(...,mode)

where y is a matrix of audio samples.  If y has two columns, then
the audio playback is in stereo.  The y input can be of types 
float, double, int32, int16, int8, uint8.  For float and 
double types, the sample values in y must be between -1 and
1.  The sampling_rate specifies the rate at which the data is 
recorded.  If not specified, the sampling_rate defaults to 11025Hz.
Finally, you can specify a playback mode of 'sync' which is synchronous
playback or a playback mode of 'async' which is asynchronous playback.
For 'sync' playback, the wavplay function returns when the playback is
complete.  For 'async' playback, the function returns immediately (unless
a former playback is still issuing).
