Small caliber guns have higher magnitude at higher frequencies and larger caliber guns have higher(adsbygoogle = window.adsbygoogle || []).push({});

magnitude at lower frequencies. is this true ? because I am not see this in my test:

that is the fft of a 9MM gun,

As one can see there are low magnitudes at low frequencies and higher magnitudes at higher frequencies.

Also the peck frequencies are around 807 Hz. A 9MM handgun is a Small caliber gun.

that is an fft of a larger caliber gun and the magnitudes are higher at high frequencies ...

am I missing something ?
