•
-l
= Generate long (32 bit) integer sound samples.
•
-f
= Generate floating point samples.
•
-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.
•
-S integer
= Indicate at which sample to start to mix in the next input file.
•
-T fpnum
= Indicate at which time (in seconds) to start to mix in the next input file.
•
-1
= Mix in channel 1 from next sound file.
•
-2
= Mix in channel 2 from next sound file.
•
-3
= Mix in channel 3 from next sound file.
•
-4
= Mix in channel 4 from next sound file.
•
-^ intx inty
= Mix in channel x from next sound file as channel y in the output.
•
-v
= Verbose mode.
•
-R
= Continually rewrite the header while writing soundfile (WAV/AIFF).
•
-H integer
= Show a "heart-beat" to indicate progress, in style 1, 2 or 3.
•
-N
= Alert call (usually ringing the bell) when finished.
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.
