DESCRIPTION
       pacat  is  a  simple  tool  for	playing back or capturing raw or encoded audio files on a
       PulseAudio sound server.

OPTIONS
       -h | --help
	      Show help.

       --version
	      Show version information.

       -r | --record
	      Capture audio data and write it to the specified file or to STDOUT if none is spec-
	      ified. If the tool is called under the name parec this is the default.

       -p | --playback
	      Read  audio data from the specified file or STDIN if none is specified, and play it
	      back. If the tool is called under the name pacat this is the default.

       -v | --verbose
	      Enable verbose operation. Dumps the current playback time to  STDERR  during  play-
	      back/capturing.

       -s | --server=SERVER
	      Choose the server to connect to.

       -d | --device=SINKORSOURCE
	      Specify the symbolic name of the sink/source to play/record this stream on/from.

       -n | --client-name=NAME
	      Specify the client name paplay shall pass to the server when connecting.

       --stream-name=NAME
	      Specify the stream name paplay shall pass to the server when creating the stream.

       --volume=VOLUME
	      Specify  the  initial playback volume to use. Choose a value between 0 (silent) and
	      65536 (100% volume).

       --rate=SAMPLERATE
	      Capture or play back audio with the specified sample rate. Defaults to 44100 Hz.

       --format=FORMAT
	      Capture or play back audio with the specified sample format.  Specify  one  of  u8,
	      s16le,  s16be, s32le, s32be, float32le, float32be, ulaw, alaw, s32le, s32be, s24le,
	      s24be, s24-32le, s24-32be. Depending on the  endianness  of  the	CPU  the  formats
	      s16ne,  s16re,  s32ne,  s32re,  float32ne,  float32re,  s32ne, s32re, s24ne, s24re,
	      s24-32ne, s24-32re (for native, resp. reverse endian)  are  available  as  aliases.
	      Defaults to s16ne.

       --channels=CHANNELS
	      Capture  or play back audio with the specified number of channels. If more than two
	      channels are used it is recommended to use the --channel-map option below. Defaults
	      to 2.

       --channel-map=CHANNELMAP
	      Explicitly  choose a channel map when playing back this stream. The argument should
	      be a comma separated list of channel names: front-left, front-right,  mono,  front-
	      center, rear-left, rear-right, rear-center, lfe, front-left-of-center, front-right-
	      of-center, side-left,  side-right,  top-center,  top-front-center,  top-front-left,
	      top-front-right,	top-rear-left,	top-rear-right, top-rear-center, or any of the 32
	      auxiliary channel names aux0 to aux31.

       --fix-format
	      If passed, the sample format of the stream is changed to the native format  of  the
	      sink the stream is connected to.

       --fix-rate
	      If  passed,  the	sampling  rate of the stream is changed to the native rate of the
	      sink the stream is connected to.

       --fix-channels
	      If passed, the number of channels and the channel map of the stream is  changed  to
	      the  native number of channels and the native channel map of the sink the stream is
	      connected to.

       --no-remix
	      Never upmix or downmix channels.

       --no-remap
	      Never remap channels. Instead of mapping channels by their  name	this  will  match
	      them solely by their index/order.

       --latency=BYTES
	      Explicitly  configure  the  latency, with a time specified in bytes in the selected
	      sample format. If left out the server will pick  the  latency,  usually  relatively
	      high  for  power	saving reasons. Use either this option or --latency-msec, but not
	      both.

       --latency-msec=MSEC
	      Explicitly configure the latency, with a time specified in miliseconds. If left out
	      the server will pick the latency, usually relatively high for power saving reasons.
	      Use either this option or --latency, but not both.

       --process-time=BYTES
	      Explicitly configure the process time, with  a  time  specified  in  bytes  in  the
	      selected	sample	format.  If  left  out the server will pick the process time. Use
	      either this option or --process-time-msec, but not both.

       --process-time-msec=MSEC
	      Explicitly configure the process time, with a time  specified  in  miliseconds.  If
	      left  out  the  server  will  pick  the  process	time.  Use  either this option or
	      --process-time, but not both.

       --property=PROPERTY=VALUE
	      Attach a property to the client and stream. May be used multiple times

       --raw  Play/record raw audio data. This is the default if this program is invoked as pacat
	      , parec or pamon

       --file-format[=FFORMAT]
	      Play/record encoded audio data in the file format specified. This is the default if
	      this program is invoked as paplay and parecord

       --list-file-formats
	      List supported file formats.
