I need a microphone to record a 20-to 200Hz (especially around 100Hz I need a decent resolution of about 1Hz)
It should be small, pick up signal in shotgun pattern (or it really doesn’t matter, I’ll record from about 1inch away from the source)

I’ll use it to measure the resonance frequency of rubber belts (timing belts)
the enviroment: near the timing belt of an egine (a stopped, cold engine) – should be small enough

I’ll plug it into a computer, than measure with a program the frequency (and from the frequency I’ll work out the tension in the belt)
(I’ll calibrate my program first.. i cannot assume that the microphone is well adjusted.. so I’ll use a diapason to tune it. )
I tried with a 3$ cheap genius microphone.. it really sucks (even if for voice on skipe works great) – on low frequencies such as 100hz (is not so low) and with very little intensiti of the sound (maybe up to 30db) it poses a bit of a challenge..I’m looking for mics under 100$, and small enough (room around an engine is not great). I thought there are specialized microphones (there are some automotive SDVs for this operation.. very expensive)
