Usage: $program_name [GENERAL OPTIONS] [FORMAT OPTIONS] FILE [EFFECT]...
Play/record sound files to/from unix style sound devices.

GENERAL OPTIONS:

General options should only be specified one.

  -d, --device=DEVICE          use DEVICE for input/output
  -V, --verbose                print verbose information
  -h, --help                   display this help and exit
      --version                output version information and exit

FORMAT OPTIONS:

File options can be specified for each filename.  Multiple filenames can
be specified when playing audio files but they must all be of
the data type and sample rates.

  -c, --channels=CHANNELS      specifies the number of sound channels in FILE
  -f, --format=FORMAT          specifies bit format of sample
                               FORMAT is either s, u, U, A, a, or g
  -r, --rate=RATE              sample rate in hertz of FILE
  -s, --size=SIZE              interpret size of sample
                               SIZE is either b, w, l, f, d, or D
  -t, --type=TYPE              specifies file format of FILE
  -v, --volume=VOLUME          change amplitude
  -x, --xinu                   reverse bit order of sample
                               (only works with 16-bit and 32-bit integer data)
      --file=FILENAME          specify filename

EFFECTs are one or more of the following:  avg, band, chorus, copy, cut, 
deemph, echo, echos, flanger, highp, lowp, map, mask, phaser, pick,
polyphase, rate, repeat, resample, reverb, reverse, split, stat, vibro.

See sox man page for detailed information on supported file types, data
formats, and effect options."
