NAME
       gwavr - record a GSM compressed wave audio file

SYNOPSYS
       gwavr [ -f filename ] [ -r samplerate ] [ -d sampledepth ]
       [ -c numchans ] [-s l | m | c ]

DESCRIPTION
       gwavr will record a PCM encoded  WAV  file  from  /dev/dsp
       then  compress the data with the GSM algorithm leaving the
       file as small as 1/10th its usual size. 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, gwavr will output its usage.

OPTIONS
       -f filename
              Uses filename as the  name  of  the  recorded  wave
              file.  The  default  is  untitled.wav which will be
              used if -f is not given.

       -r samplerate
              Asks for samplerate to be used  as  the  number  of
              samples  per  second to be recorded.  Common values
              are 44100, 22050, 11025, 8000.  The  default  value
              is 8000.

       -d sampledepth
              Uses  sampledepth  as the number of bits to use for
              each sample. Valid values are 16 and 8.

       -c numchans
              Uses numchans channels in recording.  Valid  values
              are  2  for  a  stereo  recording, and 1 for a mono
              recording.

       -l length
              Records for length seconds then stops. This is  not
              a  required  option.  You may simply ^C the program
              and it will exit gracefully.

       -s m|l|c
              Sets the mixer to the appropriate recording source.
              l=line,  m=mic  and c=cdrom.  If a mixer is already
              running, it can be used to specify recording source
              and volume levels.
