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 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.
-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.
