       -V, --version
              Print version and exit

       -v, --verbose
              Increase verbosity level (may be used multiple times)

       -L, --list-supported
              list supported schemes and formats

       -i,--input=FILE_URI
              Input file URI

       -o,--output=FILE_URI
              Output file URI

       --input-format=FILE_FORMAT
              Force input file format

       --output-format=FILE_FORMAT
              Force output file format

       --frame-length=TIME
              Duration of the internal frames, TIME units

       -r,--rate=INT
              Output sample rate, Hz

       --resampler-backend=ENUM
              Resampler  backend   (possible  values="default",  "builtin",  "speex",  "speexdec"
              default=`default')

       --resampler-profile=ENUM
              Resampler profile  (possible values="low", "medium", "high" default=`medium')

       --profiling
              Enable self profiling  (default=off)

       --color=ENUM
              Set colored logging mode  for  stderr  output  (possible  values="auto",  "always",
              "never" default=`auto')

   File URI
       --input and --output options require a file URI in one of the following forms:

       • file:///ABS/PATH -- absolute file path

       • file://localhost/ABS/PATH -- absolute file path (alternative form; only "localhost" host
         is supported)

       • file:/ABS/PATH -- absolute file path (alternative form)

       • file:REL/PATH -- relative file path

       • file://- -- stdout

       • file:- -- stdout (alternative form)

       Examples:

       • file:///home/user/test.wav

       • file://localhost/home/user/test.wav

       • file:/home/user/test.wav

       • file:./test.wav

       • file:-

       The list of supported file formats can be retrieved using --list-supported option.

       If the --output is omitted, the conversion results are discarded.

       The --input-format and --output-format options can be used to force the  file  format.  If
       the  option  is  omitted, the file format is auto-detected. This option is always required
       for stdin or stdout.

       The path component of the provided URI  is  percent-decoded.  For  convenience,  unencoded
       characters are allowed as well, except that % should be always encoded as %25.

       For example, the file named /foo/bar%/[baz] may be specified using either of the following
       URIs: file:///foo%2Fbar%25%2F%5Bbaz%5D and file:///foo/bar%25/[baz].

EXAMPLES

       Convert sample rate to 48k:

          $ roc-copy -vv --rate=48000 -i file:input.wav -o file:output.wav

       Drop output results (useful for benchmarking):

          $ roc-copy -vv --rate=48000 -i file:input.wav

       Input from stdin, output to stdout:

          $ roc-copy -vv --input-format=wav -i file:- \
              --output-format=wav -o file:- >./output.wav <./input.wav
