.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
program copies the audio devices to the named audiofile, or the standard
|
|
output if no file is named.
|
|
The output file will contain either a Sun/NeXT audio header (default), a
|
|
RIFF/WAVE audio header or no header at all. For Sun output files when
|
|
using a linear PCM encoding, we always output big-endian signed samples,
|
|
possibly after converting these from little-endian and/or unsigned
|
|
samples. For RIFF/WAVE files, we always use little-endian, signed
|
|
samples, also converting if necessary (there is no support for RIFX output.)
|
|
.Sh OPTIONS
|
|
The following options are available:
|
|
.Bl -tag -width 123456
|
|
.It Fl a
|
|
Append to the specified file, rather than overwriting.
|
|
.It Fl b
|
|
Set the balance to
|
|
.Ar balance .
|
|
This value must be between 0 and 63.
|
|
.It Fl F
|
|
Set the output header format to
|
|
.Ar format .
|
|
Currently supported formats are
|
|
.Dq sun ,
|
|
.Dq wav
|
|
and
|
|
.Dq none
|
|
for Sun/NeXT audio, WAV and no header, respectively.
|
|
.It Fl c
|
|
Set number of channels to
|
|
.Ar channels .
|
|
.It Fl d
|
|
Set the audio device to be
|
|
.Ar device .
|
|
The default is
|
|
.Pa /dev/sound .
|
|
.It Fl e
|
|
Set encoding to either
|
|
.Dq alaw ,
|
|
.Dq ulaw
|
|
or
|
|
.Dq linear ,
|
|
or any other value reported by
|
|
.Ic audioctl encodings .
|
|
The default encoding is
|
|
.Dq ulaw .
|
|
If the output format is
|
|
.Dq sun ,
|
|
the file will contain slinear_be samples, if it is
|
|
.Dq wav ,
|
|
then slinear_le, independent of the argument to
|
|
.Fl e .
|
|
Setting the argument to
|
|
.Fl e
|
|
still may be important since it is used in an
|
|
.Xr ioctl 2
|
|
call to the kernel to choose the kind of data provided.
|
|
.It Fl f
|
|
Force. Normally when appending to audiofiles using the
|
|
.Fl a
|
|
option, the sample rates must match. The
|
|
.Fl f
|
|
option will allow a discrepancy to be ignored.
|
|
.It Fl h
|
|
Print a help message.
|
|
.It Fl i
|
|
If the audio device cannot be opened, exit now rather than wait for it.
|
|
.It Fl m
|
|
Set the monitor volume.
|
|
.It Fl P
|
|
Set the precision. This value is the number of bits per sample, and is
|
|
normally either
|
|
.Dq 8
|
|
or
|
|
.Dq 16 ,
|
|
though the values
|
|
.Dq 4 ,
|
|
.Dq 24
|
|
and
|
|
.Dq 32
|
|
are also valid.
|
|
.It Fl p
|
|
Set the output port to
|
|
.Ar port .
|
|
The valid values of
|
|
.Ar port
|
|
are
|
|
.Dq speaker ,
|
|
.Dq headphone
|
|
and
|
|
.Dq line .
|
|
.It Fl s
|
|
Set the sampling rate. This value is per-second. Typical values are
|
|
8000, 44100 and 48000, which are the telephone, CD Audio and DAT Audio
|
|
default sampling rates.
|
|
.It Fl t
|
|
Sets the maximum amount of time to record. Format is [hh:]mm:ss.
|
|
.It Fl q
|
|
Be quiet.
|
|
.It Fl V
|
|
Be verbose.
|
|
.It Fl v
|
|
Set the volume (gain) to
|
|
.Ar volume .
|
|
This value must be between 0 and 255.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
program was first seen in SunOS 5. It was first made available in
|
|
.Nx 1.4 .
|
|
RIFF/WAVE support, and support for converting signed/unsigned and
|
|
big/little-endian samples was first made available in
|
|
.Nx 1.6 .
|
|
.Sh AUTHORS
|
|
The
|
|
.Nm
|
|
program was written by Matthew R. Green \*[Lt]mrg@eterna.com.au\*[Gt].
|
|
.Sh BUGS
|
|
WAV big-endian samples are converted to little-endian, rather than
|
|
a RIFX header being written.
