.SH DESCRIPTION
.B wavr
will record a
.I PCM
encoded wav file from
.I /dev/dsp.
The sample format, length and source of the recording can all be supplied at
the command line. If a mixer program is running, it can be used to set the
recording source and volume levels of that source. Without arguments,
.B wavr
will output a short message describing its usage.
.SH OPTIONS
.TP
.B \-f filename
Uses
.I filename
as the name of the recorded wave file. The default is
untitled.wav which will be used if
.I \-f
is not given.
.TP
.B \-r samplerate
Asks for
.I samplerate
to be used as the number of samples per second to
be recorded. Common values are
.B "44100"
,
.B "22050"
,
.B "11025"
,
.B "8000"
. The default value is 8000.
.TP
.B \-d sampledepth
Uses
.I sampledepth
as the number of bits to use for each sample. Valid
values are
.B "16"
, and
.B "8"
\.
.TP
.B \-c numchans
Uses
.I numchans
channels in recording. Valid values are
.B 2
for a stereo recording, and
.B 1
for a mono recording.
.TP
.B \-l length
Stops recording after
.I length
seconds. This is not required as you can simply press ^C to stop recording and
the program will exit gracefully.
