NAME
       sine_sound - generate a sine wave directly to the sound card

SYNOPSIS
       sine_sound [-d device] [-i infilename] [-v]

DESCRIPTION
       Sine_sound is for generating a sine wave directly to the sound card.

       The  program  uses a sine lookup table to efficiently generate the sine
       wave using integer arithmetic.

       The sine wave frequency, and optional amplitude, is read from stdin, as
       a  single  whitespace  delimited  record,  frequency  followed  by  the
       optional amplitude. The amplitude must be greater than zero,  and  less
       than or equal to unity; unity is 0 dBFS.

       The default, for a null record, is a 997 Hz., -15 dBFS, sine wave.

OPTIONS
       -d device
	      sound device, (/dev/dsp).

       -i infilename
	      Input filename, (stdin).

       -v     Print the version and copyright banner of the program.
