3.15Khz modulated by 6.66667Hz at 1% 
this is should be synchronous to a turntable rotating at 33.3333rpm

3.15Khz modulated by 6.69444Hz at 1%  
this is should be asynchronous to a turntable rotating at 33.3333rpm

3.15Khz modulated by 6.66667Hz at 0.1% 
this is should be synchronous to a turntable rotating at 33.3333rpm

3.15Khz modulated by 6.94444Hz at 0.1%  (a better frequency stab at asynchronous)
this is should be asynchronous to a turntable rotating at 33.3333rpm

3.15Khz no modulation at all, this is a reference 0.0% tone generated by the same system as the above tones.  This is really just for completeness.

Flavio from pink fish media requested the following for audible use, to listen to in other words.

3.15Khz modulated by 6.66667Hz at 0.05% 
this is should be synchronous to a turntable rotating at 33.3333rpm

3.15Khz modulated by 50Hz at 0.1% 
this is should be asynchronous to a turntable rotating at 33.3333rpm
