This command is only available with the Demos installation option.
Refer to for information on how to install optional software.
record copies audio data from the audio device to a named audio file.
The output file will be prefixed by an audio file header. The encoding
information in this header is taken from the configuration of the audio
device. If no filename is present, or if the special filename `-' is
specified, output is directed to the standard output stream.
Recording begins immediately and continues until a SIGINT signal (CTRL-
C) is received. If the -t option is specified, record stops when the
specified quantity of data has been recorded.
If the audio device is unavailable (that is, another process currently
has read access), record prints an error message and exits immediately.
-a Append the data on the end of the named audio file. The
audio encoding of the file must match the audio device con-
-f Force. When the -a flag is specified, the sample rate of the
audio file must match the device configuration. If the -f
flag is also specified, sample rate differences are ignored,
with a warning message printed to the standard error.
-d dev Specify an alternate audio device from which input should be
taken. If the -d option is not specified, /dev/audio is used
as the default audio device.
-i info The `information' field of the output file header is set to
the string specified by the info argument. This option may
not be specified in conjunction with the -a argument.
-t time The time argument specifies the maximum length of time to
record. Time may be specified as a floating-point value,
indicating the number of seconds, or in the form:
hh:mm:ss.dd, where hour and minute specifications are
-v vol Specify the recording gain. vol is an integer value between
0 and 100, inclusive. If this argument is not specified, the
input volume will remain at the level most recently set by
-? Help: Print a command line usage message.
