33.3 Audio Player
=================

The following methods are used to create and use audioplayer objects.
These objects can be used to play back audio data stored in Octave
matrices and arrays.  The audioplayer object supports playback from
various devices available to the system, blocking and non-blocking
playback, convenient pausing and resuming and much more.

 -- : PLAYER = audioplayer (Y, FS)
 -- : PLAYER = audioplayer (Y, FS, NBITS)
 -- : PLAYER = audioplayer (Y, FS, NBITS, ID)
 -- : PLAYER = audioplayer (RECORDER)
 -- : PLAYER = audioplayer (RECORDER, ID)
     Create an audioplayer object that will play back data Y at sample
     rate FS.

     The optional arguments NBITS, and ID specify the bit depth and
     player device id, respectively.  Device IDs may be found using the
     audiodevinfo function.  Given an audioplayer object, use the data
     from the object to initialize the player.

     The signal Y can be a vector or a two-dimensional array.

     The following example will create an audioplayer object that will
     play back one second of white noise at 44100 sample rate using 8
     bits per sample.

          y = 0.25 * randn (2, 44100);
          player = audioplayer (y, 44100, 8);
          play (player);
