Not sure exactly what your situation is, but here are some potential instructions.


First, put both the data wave file and tacho wave file into input basket:





Go to Time Data Selection worksheet and press "Replace". Both the data and tacho file are available, but separate.  Select <ALL> to see both files.





Highlight the wave file with the tacho, and press the button with the blue arrow on it.  The tacho channel can be moved to the data file:




Assuming the rpm is in a pulse format, the TACHO_TO_RPM_PULSE function in Time Signal Calculator can be used to convert the pulses to a rpm trace.




Press the "Save As" button to store the data and rpm trace together.  Then in Audio replay, the order filter can be used.


Hope that helps!
