I never had any luck with the documented Spiricom tones, as you said they do not sound right. What I did discover is a program called audio mulch. A demo version is free to use for 30 days. I used the 10 harmonic mixer with a base frequency of 102hz in my early optical Spiricom experiments. The sound is much closer to what is heard on Spiricom recordings.

I'm attaching a screen shot of the software in operation. The adjustment of the 10 harmonic levels is critical. I found optimum adjustment is by trying to make as flat a line as possible in the waveform monitor box. This is not as easy as it sounds, the adjustments interact with one another.
