DESCRIPTION
       pacat is a simple tool for playing back or  capturing  raw  or  encoded
       audio files on a PulseAudio sound server. It understands all audio file
       formats supported by libsndfile.

OPTIONS
       -h | --help
	      Show help.

       --version
	      Show version information.

       -r | --record
	      Capture audio data and write it to the specified file or to STD‐
	      OUT  if  none is specified. 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 playback/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.

       --monitor-stream=INDEX
	      Record from the sink input with index INDEX.

       -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	 chan‐
	      nels.  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 mil‐
	      liseconds. 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.

LIMITATIONS
       Due  to a limitation in libsndfile paplay currently does not always set
       the correct channel mapping for playback	 of  multichannel  (i.e.  sur‐
       round)  audio  files, even if the channel mapping information is avail‐
       able in the audio file.
