NAME
  atone	- Generate a sine wave to stdout

SYNOPSIS
  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.
