No look where freqmul is obtained.

	unit->mFreqMul = unit->mRate->mSampleDur;

freqmul is set to mSampleDur which is 1/sampleRate.
Thus if freq is 600 and sample rate is 48000, then freq * freqmul will 
be 1/80. in other words it will take 80 samples to complete a cycle. 
48000 samples per second / 80 samples per cycle = 600 cycles per second.
