SBCONV(1)                USER COMMANDS                  SBCONV(1)



NAME
     sbconv - convert sound file format

SYNOPSIS
     sbconv [options] input_filename  output_filename

DESCRIPTION
     sbconv reads the specified input_filename, converts the data
     to  the  specified  output  format  and  saves  the  data in
     output_filename.  The input_filename must be stored in  Sony
     sound(4) format.

OPTIONS
     For specifying the compressed output file format:

          -mulaw    specifies mu-law (default).

          -alaw     specifies  A-law.

          -strpcm   specifies straight PCM.

          -adpcm1   specifies the Sony format ADPCM.

          -adpcm2   specifies CD-ROM mode 2; user data ADPCM.

          NOTE
          Because the -adpcm1 and -adpcm2 options  are  function-
          ally  identical, it is recommended that you use -adpcm1
          option because it does  not  include  redundant  header
          information.  The -adpcm2 option is provided for direct
          playback of CD-ROM sector data.

     For specifying the number of channels:

          -mono     specifies monaural (default).

          -stereo   specifies stereo.

     For specifying the number of quantifier bits (data width):

          -4        specifies 4-bit quantization (ADPCM default).

          -8        specifies 8-bit  quantization  (straight  PCM
                    default).

          -16       specifies 16-bit quantization.

     For specifying emphasis (ADPCM only):

          +emphasis specifies use emphasis.

          -emphasis specifies do not use emphasis (default).



                                                                1





SBCONV(1)                USER COMMANDS                  SBCONV(1)



     For specifying the sampling frequency:

          -8000     specifies 8 kHz (default).

          -9450     specifies 9.45 kHz.

          -18900    specifies 18.9 kHz.

          -37800    specifies 37.8 kHz.

     Multiple options can be specified.  For example, to  specify
     Sony  format  ADPCM,  monaural,  no  emphasis,  at 18.9 kHz,
     enter:

          % sbconv -adpcm1 -mono -18900 infile outfile

     In addition, the format can be  specified  interactively  on
     standard input/output when the -interactive option is used.

     NOTE
     Execution of this command can take a comparatively long time
     depending on the input and output formats.
