Arguments

inToneVector	a 12 elements vector representing the amplitude for each tone "C", "C#", "D", ... in the tone complex (0 = no tone, 1 = full amplitude).
inDuration	the duration (in s). If empty or not specified, 1 is used by default.
inSampleFreq	the desired sample frequency for the output signal (in Hz) if empty or not specified, 22050 is used by default.
inPhaseFlag	for choosing whether random phase has to be used or not (1 to use random phase, 0 otherwise). If empty or not specified, 1 is used by default.
