NAME
       pcmplay - play PCM files	on audio device

SYNOPSIS
       pcmplay [ -un ] [ -d dev	] [ -b size ] [	-s bits	] [ -f freq ] [	-c num
       ] [ -g gain ] file ... |	-

DESCRIPTION
       pcmplay reads one or more files (or standard input if ``-''  is	speci-
       fied)  and  plays  them	on  the	audio device.  file is assumed to be a
       headerless (``raw'') PCM	audio file.

OPTIONS
       pcmplay options may be either the traditional POSIX one letter options,
       or the GNU style	long options.  POSIX style options start with a	single
       ``-'', while GNU	long options start with	``--''.

       -u, --unsigned
	      The audio	data is	assumed	to be unsigned.	 The default is	signed
	      data.

       -n, --network
	      The  audio  data	is  assumed  to	be in network byte order (also
	      called ``big-endian'').  The default is intel byte order (``lit-
	      tle-endian'').  This option only applies to 16 bit samples.

       -d device, --device dev
	      Specify the audio	device to use.	The default is /dev/dsp.

       -b size,	--buffer size
	      Use  an  audio  output  buffer of	size Kbytes, the default is 32
	      Kbytes.  If you experience short hangs in	the audio output,  you
	      might try	to reduce or enlarge the buffer	with this option.

       -s bits,	--bits bits
	      Specify the number of bits per sample.  This must	be either 8 or
	      16 (the default is 16).

       -f freq,	--frequency freq
	      Specify the sampling frequency in	Hertz (Hz).   The  default  is
	      44100 Hz.

       -c num, --channels num
	      Specify the number of channels.  This must be either 1 (mono) or
	      2	(stereo).  The default is 2.

       -g gain,	--gain gain
	      Set audio	hardware output	gain (default: don't change).

OPERANDS
       The following operands are supported:

       file(s) The path	name(s)	of one or more input files.  If	a  dash	 ``-''
	       is  specified,  PCM  data will be read from the standard	input.
	       Input data is assumed to	be appropriate PCM audio files.	  How-
	       ever,  since  they  are headerless (raw), it is not possible to
	       recognize invalid files,	so it is possible to specify any  type
	       of file.

       BE  CAREFUL: Playing inappropriate data at a too	high volume can	damage
       your audio hardware and speakers!  Turn the volume down before  playing
       anything	 with  this  program, unless you are absolutely	sure that your
       equipment can handle it.	 Use this program at your own risk!

NOTES
       If you don't use	any options, input data	is assumed to be  linear  PCM,
       44.1  kHz,  signed  16  bit stereo in intel byte	order (little-endian).
       This is the format of CD	audio tracks.

       pcmplay does not	perform	any data conversion.  Use sox(1) if  you  need
       to convert sample rates,	number of channels or other parameters.

       Your  soundcard must support the	specified type of audio	data.  For ex-
       ample, you cannot play 16 bit samples on	an 8 bit soundcard.

BUGS
       Yes.  This is an	alpha version.
