Linux 2.6 - man page for scale (linux section 1)

SCALE(1)			  The Canonical Csound Reference			 SCALE(1)

NAME
       scale - Scale the amplitude of a sound file. .

DESCRIPTION
       Takes a sound file and scales it by applying a gain, either constant or variable. The
       scale can be specified as a multiplier, a maximum or a percentage of 0db.

SYNTAX
	   scale [OPTIONS ... ] infile

INITIALIZATION
       Flags:

       o   -A = Generate an AIFF outout file.

       o   -W = Generate an WAV outout file.

       o   -h = Generate an outout file with no header.

       o   -c = Generate 8-bit signed_char sound samples.

       o   -a = Generate alaw sound samples.

       o   -u = Generate ulaw sound samples.

       o   -s = Generate short integer sound samples.

       o   -l = Generate long (32 bit) integer sound samples.

       o   -f = Generate floating point samples.

       o   -F arg = Specifies the gain to be applied. If arg is a floating point number that gain
	   is applied uniformly to the input. Alternatively it could be a file name which
	   specifies a breakpoint file for varying the gain for different periods.

       o   -M fpnum = Scales the input so the maximum absolute displacement is the value given.

       o   -P fpnum = Scales the input so the maximum absolute displacement is the pencentage
	   given of 0db.

       o   -R = Continually rewrite the header while writing soundfile (WAV/AIFF).

       o   -H integer = Show a "heart-beat" to indicate progress, in style 1, 2 or 3.

       o   -N = Alert call (usually ringing the bell) when finished.

       o   -o fname = output file name (default: test.wav)

EXAMPLES
	       scale -s -W -F 0.96 -o out.wav sound.wav

       This creates a new sound file with a constant gain of 0.96. It is particularly useful if
       the input file is in floating point format.
