Hello. I use FMOD and there''s function FSOUND_SetFrequency(channel,frequency); How do I correctly calculate the frequency to play engine sound? Assuming I know at what RPM the engine run in the sample. I tried juct some factor: frequency = factor*current_RPM. Does it affect at what is the wav file''s sample rate? How to get that in FMOD?


If I know sample_rate:

Assuming I know:
sample_rate, sample_RPM, current_RPM

Would that be: 
sample_rate/sample_RPM = frequency/current_RPM =>
frequency = sample_rate * current_RPM/sample_RPM;

Is this right? But how to get sample frq?
