      atone	[-freq frequency] [-power power] [-phase phase]	[-peak peak] [-time
      time]

    DESCRIPTION

      atone	generates a sine wave tone on stdout in	MU255 format.  atone | aplay
      is a useful command pipeline.

    OPTIONS

      [-freq]

           Specifies the frequency in Hz.  Defaults	to 1000.0.

      [-power]

           Specifies the power level in dB,	relative to the	digital	milliwatt.
           Defaults	to -10.0.

      [-phase]

           Specifies the initial phase of the sine wave.  Legal values are in the
           range 0 to 1024 - which represent the cycle divided into	1024 parts.
           Defaults	to 0.

      [-peak]

           Specifies the peak integer value	corresponding to the digital clipping
           level.  Defaults	to 8031.  Don't	change this one.

      [-time]

           Generates so many seconds of tone.  Default is infinite.
