SYNTAX
	   mixer [OPTIONS ... ] infile [[OPTIONS... ] infile] ...

INITIALIZATION
       Flags:

       o   -A = Generate an AIFF output file.

       o   -W = Generate an WAV output file.

       o   -h = Generate an output 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 to the following input file. 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   -S integer = Indicate at which sample to start to mix in the next input file.

       o   -T fpnum = Indicate at which time (in seconds) to start to mix in the next input file.

       o   -1 = Mix in channel 1 from next sound file.

       o   -2 = Mix in channel 2 from next sound file.

       o   -3 = Mix in channel 3 from next sound file.

       o   -4 = Mix in channel 4 from next sound file.

       o   -^ intx inty = Mix in channel x from next sound file as channel y in the output.

       o   -v = Verbose mode.

       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
       The default values are

	       mixer -s -otest -F 1.0 -S 0

       For example

	       mixer -F 0.96 in1.wav -S 300 -2 in2.aiff -S 300 -^4 1 in3.wav -o out.wav

       This creates a new sound file with a constant gain of 0.96 from in1.wav with the second channel of in2.aiff mixed in after 300 samples and
       channel 4 of in3.wav outpout as channel 1 after 300 samples.
