pcmplay reads one or more
files (or standard input if - is specified)
and plays them on the audio device.
file is assumed to be a headerless (raw) PCM
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
-n, --network |
The audio data is assumed to be in network byte order
(also called big-endian). The default is intel byte order
(little-endian). This option only applies to 16 bit
-d device, --device dev
Specify the audio device to use. The default is
-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: dont change).
The following operands are supported:
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!
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. However,
since they are headerless (raw), it is not possible to
recognize invalid files, so it is possible to specify
any type of file.
If you dont 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
pcmplay does not perform any data conversion. Use
if you need to convert sample rates, number of channels
or other parameters.
Your soundcard must support the specified type of audio
data. For example, you cannot play 16 bit samples on
an 8 bit soundcard.
